The boundary of the north american plate and the african plate in the atlantic ocean is an example of which type of plate boundary?

Divergent plate boundary

Explanation:

A divergent plate boundary can be simply defined as a contrasting plate boundary where two distinct lithospheric plate move away from one another. This results in the creation of new crust and these new materials are added along the mid oceanic ridge. This type of plate boundary is commonly observed in different locations on earth.

For example, the North American plate shares a divergent plate boundary with the Eurasian and the African plate, in the Atlantic ocean.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
