Question

Lee knew that certain events occur to create new material in the process of sea-floor spreading. Rearrange the steps into the correct order by placing the event that happens first at the top. Place the event that occurs last at the bottom.

Answer 1

Answer:

Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.

Answer 2

The correct order for in a breach in the Earth's crust, molten material pours upward is (2), (3) and (4).

What is the earth's crust?

The Earth's Crust is the planet's outermost layer. The Crust is a portion of the lithosphere that lies above the mantle and comprises tectonic plates that provide a platform for all land on Earth.

We have:

Lee knew that certain events occur to create new material in the process of sea-floor spreading.

The correct order for in a breach in the Earth's crust, molten material pours upward:

• The molten material hardens into solid strips of rock on both sides of the crack.

• The ocean floor on both sides of the crack moves farther away from the mid-ocean ridge.

• The ocean floor gradually becomes wider.

Thus, the correct order for in a breach in the Earth's crust, molten material pours upward is (2), (3) and (4).
