Question

■ plate tectonics
match each type of boundary with its description.
transform
convergent
divergent
boundary
description
c. plates slide past each other
b. plates collide and one may sink under another
a. plates move apart and new crust forms

Explanation:

• Divergent Boundary: At divergent boundaries, tectonic plates move apart. As they separate, magma rises from the mantle to fill the gap, creating new crust. This is described by "Plates move apart and new crust forms".
• Convergent Boundary: At convergent boundaries, plates collide. In some cases, one plate (usually the denser oceanic plate) sinks (subducts) beneath the other plate (either continental or less - dense oceanic). This matches "Plates collide and one may sink under another".
• Transform Boundary: At transform boundaries, plates slide past each other horizontally. There is no creation or destruction of crust, just lateral movement. This corresponds to "Plates slide past each other".

Answer:

• Divergent: A. Plates move apart and new crust forms
• Convergent: B. Plates collide and one may sink under another
• Transform: C. Plates slide past each other
