The right answer for the question that is being asked and shown above is that: "the same age as the other rock layers." the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes is that the same age as the other rock layers<span>

The ocean floor and its depth vary a lot from place to place. Maybe it is expected that the central parts of the oceans would be the deepest parts of them, while the closer the ocean floor is to the land it will be shallower, but that is not the case.
The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges. There is constant propelling of magma, and as the magma cools off quickly it creates new crust. This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.
The further away we move from the mid-ocean ridges, or rather being closer to the oceanic margins, the depth actually increases. The reason for this is the erosiove power of the water, but also the subduction zones. The erosion manages to flatten the ocean floor, thus making it deeper, while the subduction zones are the places where the oceanic plate is moving downward toward the mantle, and it create ocean trenches which are very deep, in fact the deepest parts of the oceans.

Answer:
Potassium argon dating
Explanation:
Potassium argon dating is a method used in determining the origin of a rock. I is done by comparing the ratio of radioactive argon to radioactive potassium in the rock. This method is used to date rocks that are thousands of million years old.
the assumptions made when using the Potassium argon dating include :
- no argon was left after formation of the rock
- no argon has either entered or escaped the sample since it was formed.
A natural resource is a resource that exists without any actions of humankind. This includes all valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land along with all vegetation, and animal life.To provide care for natural resources we can plant more trees, save electricity, go paperless or use less paper, quit smoking. There’s many ways to care for natural resources.
