The most ancient rocks of the Grand Canyon formed during which geologic period?
A
Permian
B
Devonian
C
Cambrian
D
Precambrian
Answer: hi there your answer is D
Precambrian
Explanation: Grand Canyon’s excellent display of layered rock is invaluable in unraveling the region’s geologic history. Extensive carving of the plateaus allows for the detailed study of the Earth's movements. Processes of stream erosion and vulcanism are also easily seen and studied.
The Colorado River has carved the Grand Canyon into four plateaus of the Colorado Plateau Province. The Province is a large area in the Southwest characterized by nearly-horizontal sedimentary rocks lifted 5,000 to 13,000 feet above sea level.
The Plateau’s arid climate produced many striking erosional forms, culminating in the Grand Canyon. The Canyon’s mile-high walls display a largely undisturbed cross section of the Earth’s crust extending back some two billion years.

Three “Granite Gorges” expose crystalline rocks formed during the early-to-middle Proterozoic Era (late Precambrian). Originally deposited as sediments and lava flows, these rocks were intensely metamorphosed about 1,750 million years ago.
Magma rose into the rocks, cooling and crystallizing into granite, and welding the region to the North American continent.
Beginning about 1,200 million years ago (late Proterozoic), 13,000 feet of sediment and lava were deposited in coastal and shallow marine environments. Mountain building about 725 million years ago lifted and tilted these rocks. Subsequent erosion removed these tilted layers from most areas leaving only the wedge-shaped remnants seen in the eastern Canyon.
Rock layers formed during the Paleozoic Era are the most conspicuous in the Grand Canyon’s walls. Coastal environments and several marine incursions from the west between 550 and 250 million years ago deposited sandstone, shale and limestone layers totaling 2,400 to 5,000 feet thick.
Layers from the Cambrian, Devonian, Mississippian, Pennsylvanian and Permian periods are present. Erosion has removed most Mesozoic Era evidence from the Park, although small remnants can be found, particularly in the western Grand Canyon.

Nearby rock outcrops suggest 4,000 to 8,000 feet of sedimentary layers from the “Age of Dinosaurs” once covered the Grand Canyon area. Cenozoic Era (the “Age of Mammals”) layers are limited to the western Grand Canyon and terraces near the river itself. A few sedimentary deposits formed in lake beds, but the most spectacular recent deposits are the lava flows and cinder cones on the Shivwits and Uinkaret plateaus. Volcanic activity began about six million years ago and has continued to within the last several thousand years. Spectacular lava cascades down the Canyon walls have helped date the Grand Canyon’s carving.
The Grand Canyon itself is a late Cenozoic feature, characteristic of renewed erosion during this time. Vigorous cutting by the snow-fed Colorado River
Precambrian is the geologic period, is the most ancient rocks of the Grand Canyon formed. Hence, option D is correct.
What is the concept of the passage?Understanding the geologic history of the area is made possible by the superb display of stratified rock at Grand Canyon. The plateaus' extensive carving has made it possible to examine the Earth's movements in great detail. It is also simple to observe and study vulcanism and stream erosion processes.
Four plateaus of the Colorado Plateau Province were formed out of the Grand Canyon by the Colorado River. The Province is a sizable region in the Southwest distinguished by sedimentary rocks that are virtually horizontal and elevated 5,000 to 13,000 feet above sea level.
The Grand Canyon is the culmination of numerous remarkable erosional structures formed by the arid climate of the Plateau. The Canyon's mile-high walls show a cross section of the Earth's crust that dates back about two billion years and is remarkably untouched.
Thus, option D is correct.

Millions of years ago, the ancestors of the modern horse were small
animals, only about 0.61 meters tall. We know this because
Answer:
Explanation:
The evolutionary lineage of the horse is among the best-documented in all paleontology. The history of the horse family, Equidae, began during the Eocene Epoch, which lasted from about 56 million to 33.9 million years ago. During the early Eocene there appeared the first ancestral horse, a hoofed, browsing mammal designated correctly as Hyracotherium but more commonly called Eohippus, the “dawn horse.” Fossils of Eohippus, which have been found in both North America and Europe, show an animal that stood 4.2 to 5 hands (about 42.7 to 50.8 cm, or 16.8 to 20 inches) high, diminutive by comparison with the modern horse, and had an arched back and raised hindquarters. The legs ended in padded feet with four functional hooves on each of the forefeet and three on each of the hind feet—quite unlike the unpadded, single-hoofed foot of modern equines. The skull lacked the large, flexible muzzle of the modern horse, and the size and shape of the cranium indicate that the brain was far smaller and less complex than that of today’s horse. The teeth, too, differed significantly from those of the modern equines, being adapted to a fairly general browser’s diet. Eohippus was, in fact, so unhorselike that its evolutionary relationship to the modern equines was at first unsuspected. It was not until paleontologists had unearthed fossils of later extinct horses that the link to Eohippus became clear.

Many internees at Manzanar objected to anyone who chose to work for the government by making war materials. Which statement most likely characterizes their opposition? They believed that internees should not help in the war effort because the internment of the Japanese was unjust. They believed that internees should not help in the war effort because their work would harm Japan and their Japanese family members. They believed that internees should not help in the war effort because they were not being paid fairly.
Answer:
They believed that internees should not help in the war effort because the internment of the Japanese was unjust.
Explanation:
With the attack on Pearl Harbor during the Second World War, the war in America began to form internally. The Axis powers in which japan was a part of in conflict with the Allied Powers, which included the United States. And as such, action was taken against the Japanese- Americans living/ settling in America.
As it was the Axis powers (Japan) that attacked an American military base, the United States' government began to order the internment of its Japanese-American citizens just because of their physical connection to the enemy. With the attack deemed as a huge threat to the national security of America, every Japanese descent American was ordered to move to the internment camps, leading to a massive round-up. Though it was never a case of trying to 'punish' them for what their home country had done to their adopted country, it was evident that the move was to 'isolate' any Japanese man and restrict any chance of an 'informer' or 'secret agent'.
So, in protest to this order, the internees objected to anyone who chose to work for the US government because the internment was an unjust and unfair act in itself to the Japanese people.
Many internees at Manzanar objected to anyone who chose to work for
the government because they believed that they should not help in the
war effort because the internment of the Japanese was unjust.
Who are Internees?An internee is an individual which is imprisoned due to military or political
reasons. In this case, Japanese-Americans were imprisoned as a result of
the attack on their camp by Japanese who they shared the same ethnicity.
In the real sense. the Japanese-Americans were isolated were isolated to
prevent further security breach and not as a form of punishment.

24. What is the purpose of all constitutions? (1 point)
Oto list the rights of citizens
Oto create a system of checks and balances
Oto establish federal authority over state governments
O to establish rules that a government must follow
The purpose of constitutions is to establish a framework of rules and principles that a government must follow. Hence option D is correct .
What is the purpose of all constitutions?These rules can cover a wide range of topics, such as the rights of citizens, the structure of government, and the limitations on governmental power.
One key purpose of constitutions is to protect the rights of citizens. Constitutions can outline individual rights such as freedom of speech, religion, and assembly. By establishing these rights, constitutions provide a framework for citizens to hold their government accountable and to protect themselves against potential abuses of power.
Another important purpose of constitutions is to create a system of checks and balances. This helps to prevent any one branch of government from becoming too powerful and ensures that each branch has a specific role to play in governing.
Additionally, constitutions can establish federal authority over state governments, as is the case in the United States. This helps to ensure that the federal government can act in the best interest of the nation as a whole, rather than just individual states.
Overall, the purpose of all constitutions is to provide a set of rules and principles that a government must follow, in order to protect the rights of citizens and prevent abuses of power.

In the twentieth century, conflicts such as the two world wars and the Cold War occurred on a global scale. Develop an argument that evaluates the extent to which global conflicts led to cultural or social changes during this period.
The correct answer to this open question is the following.
In the twentieth century, conflicts such as the two world wars and the Cold War occurred on a global scale.
These global conflicts led to cultural or social changes during this period and marked social divisions that lasted for many years, affecting foreign relations on one side, and internal societal changes, on the other.
The two world wars left an imprint of pain and suffering in the collective memory of Europe. Foreign relationships changed and the partition f power in the world changed too.
Soviet leader Joseph Stalin opted to keep the occupied countries and instilled Communism. We are talking about East Germany, Romania, Albania, Hungary, Poland, and Czechoslovakia. The USSR supported the spread of Communism all over the world and the United States applied the policy of containment, trying to stop the spread of that political and economic ideology.
Both countries supported their respective sides in the Korean War and the Vietnam War. They also competed in the arms race and years later, in the space race.
These issues created too much tension and the world was on the brink of another war in the times of the Cuban missile crisis.
The extent to which global conflicts led to cultural or social changes during this period is analysed thus:
There was the spread of communismThere was increased patriotism in some countriesThis period ushered in industrializationThe two World Wars and the Cold War fought between the Soviet Union and the United States over communism and its spread led to various changes, both societal and cultural.
This brought about increased patriotism as the people were ready and willing to be taxed so that their military programs would be upgraded.
