Explanation:

The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act, carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates, have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air.How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are:

Riding a bike or walking instead of driving.

Taking a bus or carpooling.

Buying a car that has greater fuel efficiency.

Turning off lights and appliances when they are not in use.

Using energy efficient light bulbs and appliances.

Buying fewer things that are manufactured using fossil fuels.

Answer:

The United States Constitution refers to the powers of the President and the powers of the US Congress. Regarding foreign policy, the President of the United States is the chief diplomat of the United States. He can sign international treaties that later can be ratified by Congress. On the other hand, Congress discusses and comments those treaties and trade agreements and sent it to the President to sign them. Another important function of Congress regarding foreign policy is that only the US Congress can declare war to other nations.

Answer:

A.warmer than present

Explanation:

During most of the Mesozoic Era, the Earth was warmer than present.

This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.

This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.

Answer:

Universal gas constant (which could also refer to molar gas constant, universal gas constant, or ideal gas constant) is essentially the units of energy of temperature. Since all energy is just heat, the universal gas constant, at least to my knowledge, it just a theorem to describe the heat of the temperature.

Answer:

(a) check the explanation

(b) the possible values of b is 6i or -29

Explanation:

Given function;

16x⁴ - 4x³– 4b²x² + 7bx + 18

(a)

factor of the given function = 2x + b

then, 2x + b = 0

x = -b/2

substitute the value of b into the given function;

16x⁴ - 4x³– 4b²x² + 7bx + 18

[tex]16(\frac{-b}{2} )^4 -4(\frac{-b}{2})^3-4b^2(\frac{-b}{2})^2 +7b(\frac{-b}{2})+18=0\\\\b^4+\frac{b^3}{2} -b^4-\frac{7b^2}{2} +18=0\\\\\frac{b^3}{2} -\frac{7b^2}{2} +18=0\\\\multiply\ through \ by \ "2"\\\\b^3-7b^2+36 =0 \ (shown)[/tex]

(b)

b³ - 7b² + 36 = 0

b²(b - 7) + 36 = 0

b²(b - 7) = -36

b² = -36                or b - 7 = -36

b = √(-36)             or  b = -36 + 7

b = √(-1) x √(36)   or  b = -29

b = 6i       or   -29              

Answer:

When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens

Explanation:

There was the main difference of the acid and the normal rain. The acid rain was the slowly dissolves rocks and the normal rain are not the dissolves of the rock.

The rock, according to geology, is a part of the solid surface. The rock is the collection of these cemented mineral grains. The rocks are small and bigger. The small rocks are also known as pebbles. The type of natural resource is rock. The rocks are used for making the building.

The influence on the rock differs depending on whether it is acid rain or ordinary rain. Acid rain degrades rocks gradually as a result of chemical interactions between the acids and the ions in the stone. Pure water has a moderately acidic pH of 5.6, whereas acid rain has a pH around 4.2 and 4.4.

As a result, the normal rain from acid rain are the based on the rock breaks.

Answer:

True

Explanation:

Answer:

P=43

Explanation:

As, the both angles are linear, so if we add them, we will get 180°.

So, p+7 + 3p+1 = 4p + 8

So, 4p + 8 = 180

So, 4p = 180 - 8

4p = 172

P= 172/4

P = 43

So p+7 + 3p+7 = 43 + 7 + ( 3x43 + 1) = 180

Therefore, p = 43

Answer: The three primary methods are: Radiation Measurement. Stratigraphic Superposition. The Fossil Record.

Explanation:

Answer:

The three primary methods are: Radiation Measurement. Stratigraphic Superposition. The Fossil Record.

Explanation:

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.

The correct answer is B. A supply of inexpensive labor

Explanation:

Manufacturing most products in Mexico is cheaper than doing this in the U.S. The main reason for this is that in Mexico labor (workers needed for production) is cheaper than in the U.S. This factor is related to the fact the currency in Mexico has less value than the currency in the U.S. and the social, economic, cultural conditions are different. Besides this, production can be easily controlled in Mexico because this borders the U.S. According to this, one factor that makes some American companies locate factories in Mexico is the supply of inexpensive labor.

Answer:

Uplift raised the level of a piece of crust.

Mountains eroded.

Basaltic lava flowed from cracks in the crust.

Explanation:

A plateau can form in several different ways. It can form because of volcanic activity, the collision of plates, uplift of crust, and erosion.

Uplift that has raised a piece of crust can easily form this plateau. If the crust that is moving up is relatively flat at the top, then it will stick out in the surrounding area like a mountain will, but it will have a relatively flat top, thus making a plateau.

Erosion is very often a factor that creates plateaus. If there is a very large piece of crust that is much more solid than its surroundings, it will erode at a much slower rate. This will result in the crust around it to erode while it remains close to its initial form, thus sticking out as a higher relief form.

In the areas where there is or has been volcanic activity, it is common that plateaus as the one on the image are found. When the lava flows it fills in the valleys, cracks, holes, and when it solidifies it creates solid masses of igneous rocks. These rocks erode very slowly, so while all of the surroundings erode faster and lower down, it remains largely the same in the form of a plateau.
