Answer:

less than 200 million years old

Explanation:

The oceanic crust is composed essentially of basalt, formed by magnesian silicates (hence formerly called sima). It is 5 to 10 km thick and is denser than the continental crust because it contains more iron. Seismic waves have a speed of 7 km / s.

Ocean dorsals are geologically young relief forms, so none of the existing dorsals are more than 200 million years old, which can be considered very little compared to the 4.6 billion years that Earth has.

Vinil7 [7]

A fact is a statement that is true and can be verified objectively, or proven. In other words, a fact is true and correct, no matter what. An opinion, however, is a statement that holds an element of belief; it tells how someone feels. An opinion is not always true and cannot be proven.

Are all forms of segregation negative? Is affinity segregation helpful or harmful to an ethnic group? Explain your position.

zhuklara [117]

Answer:

Segregation between races is wrong, but can sometimes be a good thing. Allow me to explain:

Explanation:

During the Jim Crow era a lot of white people would use hate speech and just be mean to African Americans all the time. By keeping them separate, African Americans wouldn’t be harassed by them. However there shouldn’t be segregation because people shouldn’t be practicing hate speech. Segregation wouldn’t be tackling the problem, it would be deflecting it.
