Answer 1

The lithosphere is the moving part of the surface of Planet Earth. It consists of the continental crust, oceanic crust, and the upper part of the mantle, called the asthenosphere. The uppermost part is crispy, and this is where brittle deformation happens, like faults, and damage from earthquakes. The lower part is warmer, since things get hotter going towards the interior of the planet, and this is where ductile deformation happens, like folding of rocks. The movement is steered by convection in the mantle, which helps push some tectonic plates together, while separating others.

The lithosphere is very important because we humans live here, and we have to interact with it. When plates come together, one result is volcanoes, which supply water, atmosphere, and new land. Understanding where the danger spots are is vital. Additionally, movement of the lithosphere is what provides us land to live on. Without tectonic uplift, erosion would have long since wiped out all dry land, and we would not be here.
