Answer:

1. Radiometric dating

2. Relative dating is used to determine the age of fossils or rock layers by by comparing it to similar rocks and fossils of known ages.

3. The youngest rock layers are at the top and the oldest are at the bottom, which is according to the law of superposition.

4. Tribolite and Pecten fossils

Fossils are used to determine the ages of rock layers. Index fossils are the most useful in determining relative aging. Index fossils are of organisms that lived for a short period of time. An index fossil allows a scientist to determine the age of the rock it is in. So if they are found in a particular age, it means they belong in that age.

5. Scientists commonly use radioactive dating methods by using radioactive decay cloak of certain elements such as potassium or carbon to date fossils or rocks.

6. Law of superposition because in terms of finding the age of the rock as an object, all that needs to be identified are the layers of the rock.

7. The nuclear decay of radioactive elements are a process that behaves in a clock-like fashion which makes it a useful tool for determining the exact age of fossils or rocks.

Ocean ridges form at convergent boundary true or false
zaharov [31]

Answer:

True!

Explanation:

Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
