Question

Why is the lithosphere rigid while the asthenosphere is not? Choose one: There are more plates making up the lithosphere. The pressure in the asthenosphere is lower than the lithosphere so the rock is softer. There are more rigid minerals in the lithosphere than in the asthenosphere. The temperature in the asthenosphere is higher than the lithosphere so the rock is softer.

Answer 1

Option D is the correct choice.

Step-by-step explanation:

• Lithosphere, the universe's strong, rocky outer portion, composed of the upper mantle's crust as well as the firm outer edge surface. This reaches an average distance of 60 miles. It splits into around a dozen different, stiff frames, or frames.
• Lithosphere crystals or formation are "rigid" which means they could flex and they can't quite float.

The other given options are not related to the given circumstances. So that Option D is the correct choice.
