The sphere of Earth that includes all living things.

They all depend on each other to function; an impact to one sphere usually affects another.

All spheres of Earth are interrelated of interdependent. This means:

Biosphere and lithosphere interaction.

When an animal dies and decomposes, its nutrients are absorbed into the soil. Plants use these nutrients to live and grow. This is an example of:

Hydrospher and atmosphere interaction

You live on the beach, which always seems to be humid, especially on hot, sunny days. But, that's because when the ocean heats up, some of its water evaporates into water vapor, making the air thick and slightly "wet". This interaction is an example of:

Hydrosphere, lithosphere and biosphere interaction

Colossal Cabe was formed years ago by underground running water. Today, it is the home to many animals, like bats. These interactions are an example of:


Which sphere is dependent on all the other spheres in order to exist?

Step 1

Rock Cycle
Rock is broken down into Regolith by weathering.

Step 2

Rock Cycle
Regolith is transported or eroded by rain or wind.

Step 3

Rock Cycle
Regolith is dumped into some type of reservoir, usually water, by deposition.

Step 4

Rock Cycle
Layers deposited begin to compact and cement together to form sedimentary rock.

Step 5

Rock Cycle
Sedimentary rock is buried deeper into the Earth's crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock.

Step 6

Rock Cycle
Metamorphic rock begins to melt back into magma.

Step 7

Rock Cycle
Magma is resurfaced from volcanic activity, cools, and becomes ingeous rock.


Plants are able to release water back into the atmosphere by a process called:

Evaporation of water is equal to precipitation of water

The hydrologic cycle maintains a balance of earth's water because:

Erosion, uplifting

The hydrologic, rock, and tectonic cycles are all interconnected. In the rock cycle, water moves regolith during..., and the tectonic cycle resurfaces rock through...

Sun and interior of earth (core)

The hydrologic, rock, and tectonic cycles are powered by two main energy sources. They are the:

Seafloor spreading

The tectonic cycle describes the movement of earth's crust. Recycled "new" oceanic crust is formed by... at divergent boundaries.


... occurs at convergent boundaries, where one layer of crust sinks into the asthenosphere when it collides with another layer of crust.

Step 1

Hydrologic (water) cycle
Evaporation would change the drop of water vapor, a gas, which would rise into the atmosphere.

Step 2

Hydrologic (water) cycle
The atmosphere is cooler, so the drop of water would change from a gas back into a liquid through condensation.

Step 3

Hydrologic (water) cycle
As more water vapor condenses into liquid, the drop of water will eventually drop to earth's surface as precipitation.

Step 4

Hydrologic (water) Cycle
The drop of water falls to the ground as rain and is absorbed as groundwater.

Step 5

Hydrologic (water) Cycle
The goundwater flows into a river which empties back into the ocean.


Earth's hydrologic, rock, and tectonic cycles continuously recycle earth's materials.


Earth's hydrologic, rock, and tectonic cycles contribute to a balance or equilibrium of earth's materials.
