the law of uniformitarianism, states that the laws of nature may change with time and that the rates at which things happen on earth today are different than they were in the past.
true
false
which of the following is a reliable way to date the age of the earth?
mountain ranges
meteorites
deep sea trenches
old rocks made on earth

Explanation:

• For the first question: Earth materials are constantly cycled, so dating Earth - formed rocks is difficult.
• For the second question: The law of uniformitarianism states that the laws of nature are constant (not changing), so the statement is false.
• For the third question: Meteorites are from space and not affected by Earth's geological cycling, so they are a reliable way to date Earth.

Answer:

1. True
2. False
3. Meteorites
