While I don't have a diagram based on my knowledge krill are omnivorous.
you have carried out radiometric analysis on four igneous rocks uncovered at several sites you are exploring. from the percent lead you determine in each case, what is the approximate age of the rock?
lead is extracted from uranium to create lead ore. A system might go through a geological process that removes lead, leaving the resultant system devoid of uranium.
Rocks are frequently dated using lead isotopes, which offer some of the best proof of the Earth's age. The activities producing lead isotopes must satisfy all four requirements of a natural clock—an irreversible process, a uniform rate, a starting condition, and a final condition—in order to be utilised as a natural clock to determine the age of the world. This approach ultimately influenced the creation of isochrons, which plot two isotopes against one another to determine the age of the mineral or rock.
Scientists can establish how long the parent isotope has existed by comparing the relative levels of the two isotopes and understanding the rate of decay.

The constitution is the supreme law of the land how can this be seen by looking at the organization of the constitution itself
The Constitution's structure shows that it is the Supreme Law of the land by explicitly stating that it is the supreme law of the land.
What does the Constitution say?In Article VI, Clause 2, which is also known as the "Supremacy Clause," the Constitution states that it is the "Supreme Law of the Land." And along with it, all federal laws that are made based on the constitution are also supreme to all other laws in the United States.
What this meant was that no law in the United States was to be contrary to the Constitution. This included laws by states, and even laws by the federal government. If a law was found to be unconstitutional, it was to be struck down. This is how the structure of the Constitution enforces it's supremacy.

What are the two independent methods used in dating events in earth's history? select all that apply.
Radioactive Decay and Relative Dating are the two independent methods used in dating events in earth's history.
What is the process of Radioactive Decay ?1) The spontaneous breakdown of an atom's unstable nucleus is known as radioactive decay.
2) The particle or photon emission.
One such instance of radioactive decay is alpha decay, in which an atomic nucleus generates an alpha particle (helium nucleus).
3) Typically, a more stable element with a smaller atomic number is the end outcome.
For instance, in alpha decay, an atom changes into an atom with a lowered atomic number of two and a reduced mass number of four. For instance, nuclear fission is a type of radioactive decay in which a significant quantity of energy is produced as an atom's nucleus breaks into smaller pieces.

Geologists determine absolute age by comparing the amounts of radioactive and nonradioactive elements in Igneous Rock.
Igneous rocks from the Latin word for fire form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface.
Igneous rocks are defined as types of rocks that are formed when molten rock liquefied by intense heat and pressure cools to a solid state. Lava is molten rock flowing out of fissures or vents at volcanic centers when cooled, they form rocks such as basalt, rhyolite, or obsidian.

in which ways does the movement of the solar equator affect precipitation in the tropics and subtropics
The intertropical convergence zone corresponds to the solar equator, where the intensity of the Sun's energy causes evaporation and air movement that boosts precipitation.
The area where the northeast and southeast trade winds converge is known as the Intertropical Convergence Zone sometimes referred to as the doldrums or the calms by sailors due to its repetitively windless conditions. It rounds the planet close to the thermal equator, however the exact location changes with the seasons. It is known as the near-equatorial trough when it is located close to the geographic Equator.

What is the name for a small earthquake that occurs prior to a major earthquake?
Foreshock is the name for a small earthquake that occurs prior to a major earthquake.
An earthquake known as a foreshock occurs prior to a major shock and is geographically and temporally related to it. Aftershocks are smaller earthquakes that take place in the same general area days to years following a larger occurrence or "mainshock." They occur prior to the resumption of the background seismicity level and within 1-2 fault lengths of one another.
Within three days following an earthquake anywhere in the world, a large earthquake is likely to happen nearby in more than 6% of cases. This means that there is a 94% likelihood that a given earthquake is not a foreshock. For instance, in California, foreshocks were present in around half of the greatest earthquakes, but not in the other half.

Why is there a need for our water supply to be managed and distributed?
There is a need for our water supply to be managed and distributed because it delivers water from the treatment facility to the consumer. Additionally, distribution systems might offer storage in addition to adequate flow and pressure for fire protection.
A water supply system provides services essential to the operation of industrialized society as well as essential for emergency preparedness and post-disaster recovery. It transports water from sources to customers (e.g., earthquakes). A water distribution system is a component of the water supply network that transports potable water from a centralized treatment facility or wells to consumers to meet their needs for household use, business use, industrial use, and firefighting. The majority of the water in urban and suburban areas is piped in from a central water supply. A river, a lake that formed naturally, a reservoir created by a dam, or a number of deep wells could serve as the water source. Aqueducts are used to transport water from distant reservoirs to numerous large cities.

does total runoff occur over a longer or shorter time span after an area has been urbanized? runoff occurs over a time after urbanization
Runoff occurs over a shorter time after urbanization.
Under natural conditions, runoff velocities are lower than in built-up areas and runoff occurs over a longer period of time. Also, the pre-development peak runoff rate is much lower than the post-development peak runoff rate due to attenuation and absorption by soil and vegetation.
Impermeable surfaces with urbanization reduce infiltration, increase surface runoff, and alter the pathways by which water reaches urban streams. Temperature, wind speed and humidity are the main meteorological factors affecting runoff. They affect the rate of evaporation and transpiration, thus affecting soil moisture content and infiltration rates, and ultimately runoff.
