2. Which components of the Earth's systems MOST CORRECTLY matched with their related topics?

Bisphere:plate tectonics

Cyrosphere:earth’s mantle

Geosphere:glacier thickness

Hydrosphere:ocean currents

Hydrosphere:ocean currents

Explanation:

Earth's biosphere has to do with the parts of the earth where life exists. The biosphere includes portions of the earth such as the lithosphere (the outer part of the earth), the atmosphere, the hydrosphere(the region of the earth's water resources).

Cyrosphere refers to those portions of the earth in which water is in solid form or frozen, such as sea ice, lake ice,glaciers and frozen ground. For example, the waters in the Arctic and in Antarctica. Related topics includes glacier thickness.

Geosphere is made up of the solid part of the earth; its rocks, minerals and surface and interior landforms. Related topics in the geosphere include plate tectonics, mountain formation, ocean ridges, earth's mantle. etc.

Hydrosphere refers to all the regions where water is found on the earth. It includes, surface water, underground water, ice as well as water vapor. A related topic is ocean currents.
