Question

Explicação
## Step 1The question is asking us to identify which subsystem of Earth is responsible for the creation and destruction of Earth's topography, particularly in the context of volcanic eruptions. The options provided are the atmosphere, geosphere, biosphere, and hydrosphere.## Step 2The atmosphere is the layer of gases surrounding the Earth. It does not directly contribute to the creation or destruction of Earth's topography.## Step 3The biosphere refers to the part of the Earth where life exists. This includes all living organisms and their habitats. While volcanic eruptions can impact the biosphere, it is not the primary subsystem responsible for the creation and destruction of Earth's topography.## Step 4The hydrosphere includes all the water on Earth, such as oceans, lakes, and rivers. While volcanic eruptions can impact the hydrosphere, it is not the primary subsystem responsible for the creation and destruction of Earth's topography.## Step 5The geosphere is the solid part of the Earth, including the crust, mantle, and core. This is where volcanic eruptions occur, as magma from the Earth's interior rises to the surface, creating new landforms and altering existing ones. Therefore, the geosphere is the subsystem of Earth that is responsible for the creation and destruction of Earth's topography, particularly in the context of volcanic eruptions.
