The brittle lithosphere cracks under pressure from the moving asthenosphere.
|
|
|
The lithosphere cracks and deforms under the weight of the continents.
|
|
|
Earthquakes form cracks in the lithosphere that grow larger over time, creating new plates.
|
|
|
Shortly after Earth formed, the lithosphere cooled, causing it to contract and crack.

Detailed explanation-1: -Which statement best explains why earths lithosphere is broken into tectonic plates? The brittle lithosphere cracks under pressure from the moving asthenosphere.
Detailed explanation-2: -Answer and Explanation: The type of stresses that broke the Earth’s lithosphere into plates are the tectonic forces. Tectonic forces come from the movement of the mantle and core, where the hot, liquid rock will tend to rise and the cool, liquid rock sink.
Detailed explanation-3: -The system of ideas behind plate tectonics theory suggests that Earth’s outer shell (lithosphere) is divided into several plates that glide over the Earth’s rocky inner layer above the soft core (mantle).
Detailed explanation-4: -The correct answer is Crust and Upper mantle. It is the outer solid part of the earth, including the crust and uppermost mantle.
