The Earth has a long history that stretches back over 4.6 billion years ago when bodies of rock began to collide together and form larger rocks in the process. The Earth was the product of these rock collisions, and when the Earth was formed into a planet it was extremely hot for several reasons.

Internal pressure helped to raise temperatures from the gravitational contact of these large rock collisions. There were also large amounts of radioactive elements early in the history of our planet that released heat through radioactive decay. The other reason is tied into the first, with multiple rocks and asteroids were colliding with Earth and these large bodies traveled at tremendous speeds through space which created immense heat on impact with Earth.

Which of the following statements is true?
dolphi86 [110]

Answer:

C. There is more usable freshwater below the earth's surface than there is above it.

Explanation:

A. Most of earth's freshwater is found in lakes and rivers.

Although lakes and river are one of the surface water that house the highest percentage of fresh water (about 0.3%) but most of the earths fresh water are not found in lakes and rivers but are found in ground water and ice caps and glaciers. This statement is definitely not true.

B. Almost half of the water in the U.S. is used for mining and industry.

According to USGS(US geological survey) most water usage in the US is for thermoelectric power and irrigation followed by public supply before the use for mining and industry comes in. The statement is wrong to say almost half of the water in the US is used for mining and industry.

C. There is more usable freshwater below the earth's surface than there is above it.

Fresh water in ground water constitute about 30.1 % fresh water found in the earth. In fact some of the fresh water found on surface water bodies like rivers migrated from ground water. Groundwater is the largest reservoir of usable fresh water. The statement is correct and it is true.

D. Water is called the "universal solvent" because it dissolves in most other liquids.

Water is regarded as a universal solvent because it dissolves more substances than any other liquid not because it dissolve in most other liquids.

What is the positive solution to the eqution 0=1/3x^2-3
Nuetrik [128]
It's 3...
First you add 3 to both sides.(1/3x^2=3)
Then multiply both sides by 3. (x^2=9)
Then take the square root of both sides. (x=+-3)
Finally since it is asking for the positive solution, you can remove the negative sign and so the answer is 3.

Question 5 1 pts Which statement about science an religion is NOT true? Science is limited to the natural world, whereas many re
mash [69]

Answer:

The best answer to the question: Which statement about science and religion is NOT true? Would be: No scientists are religious.

Explanation:

Basically that would be the one WRONG statement because it would require for us to know that in truth all scientists are not religious, which is not possible. This statement first arises from the conclusion that science and religion are two completely incompatible areas, and therefore, any person who belongs to one cannot belong to the other. Although it is true that in many ways it seems as if science and religion do not coincide, it must be remembered that it was religious belief, and the desire to explain why the world worked the way it did, what inspired first philosophers like Aristotle, Plato, Saint Augustine, to name a few, to observe and investigate the natural world around them. Also, historically speaking, there have been many men who were religious and who became vital to the development of scientific tenets and fields of study. For all these reasons, the statement that No scientis are religious, is false.
