New land is formed when rivers enter the ocean
Answer:
The landform that will form is a mid-ocean ridge.
Explanation:
When tectonic plates move away from each other they form a divergent plate boundary. At this type of boundary, as the plates move away, a gap starts to open up gradually. This gap becomes wider and wider over time and the crust is made much less thick, which in turn presents a good opportunity for the magma to come out on the surface.
Because the crust is weaker and thinner, the magma manages to rise through it and rich the surface relatively easily. As it does, the magma reaching the surface, or rather the bottom of the ocean, it solidifies in the water and as more and more magma comes out it piles up. By piling up and constantly creating new rock an underwater mountain chain starts to form and this type of mountain chain is known as a mid-ocean ridge.
The Andes have formed as a result of a subduction zone while the Himalayas have formed as a result of a convergent plate boundary.
Answer:
Greenhouse affect - atmosphere traps heat
Ice age - coldest phase of climate cycle
Sun's output - can vary
Greenhouse gases - atmosphere traps even more heat
For continental U.S. the answer is never. Since the earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the su, one would have to be less than 23.5 degrees above or below the equator to have the sun pass direclty overhead
