Answer 2

Structure of the Earth's Crust

The Earth's lithosphere is the solid, rocky outer shell of the Earth. It consists of the Earth's crust and the upper part of the mantle, known as the asthenosphere. The lithosphere is divided into large blocks called lithospheric plates, which move relative to the more plastic asthenosphere. The thickness of the lithosphere varies from 5 to 80 kilometers or more. The Earth's crust can be classified into two types: continental crust and oceanic crust. The continental crust is thicker and more solid compared to the oceanic crust. Geologists are the scientists who study the lithosphere and its structure.

Based on the provided text, we can determine the structure of the Earth's crust by looking at the following sentences:

1. "The lithosphere is the solid, rocky outer shell of the Earth." 2. "It consists of the Earth's crust and the upper part of the mantle (up to the asthenosphere)." 3. "The lithosphere is divided into large blocks called lithospheric plates." 6. "The Earth's crust can be classified into two types." 7. "The continental crust is thicker and more solid compared to the oceanic crust."

Therefore, the sentences that help determine the structure of the Earth's crust are 1, 2, 3, 6, and 7.
