Question

2. Explain why, in the past 100 years, the continents seem to be relatively unchanged.

Answer 1

We now understand that the continents are supported by enormous rock slabs known as tectonic plates. Plate tectonics is the name of the process in which the plates are constantly moving and interacting. Even now, the continents are continuously shifting. Seafloor spreading zones and enormous rift valleys are some of the most active tectonic regions.

Step-by-step explanation:

They've basically just slowed down.

Answer 2

because continental drift is slower/slow?
