List the parts of Earth's crust in order of generally increasing density: (a) oceanic crust, (b) continental crust, (c) asthenosphere, (d) lithosphere.

Answer: Parts of the Earth Crust been arranged in order of increasing density;

- Continental Crust

- Oceanic Crust

- Lithosphere

- Asthenosphere

Explanation:

The Continental Crust takes up a space of between 20km - 70km i. e it's thickness, it has a density of about 2.7 grams per cubic centimeter.

The Oceanic Crust with less thickness has about 3.0 grams per cubic centimeter. The lithosphere is about 100km thick while the Asthenosphere is about 100km - 200km below Earth surface.
