Earth's Cycles Project

Part I 

Rock Cycle
1. How does a metamorphic rock become a sedimentary rock?
-Weathering breaks down the rock into sediments. Sediments moves by erosion into water. Then by compaction and cementation sedimentary rock forms.

2. How does Magma change into metamorphic rocks?
-Magma goes out and called Lava. Lava gets cold and turns into igneous rock. Igneous rock changes its shape by heat and pressure into metamorphic rock.

Carbon Cycle
3. How does a consumer become a fossil fuel?
-When they die, their remains goes underground by decomposers and turns into fossil fuel.

4. How can a fossil fuel be used in photosynthesis?
-Burning of fossil fuels releases CO2 emissions into air, and in photosynthesis plants use CO2 to produce O2.

Water Cycle
5. How does a lake water turn into clouds?
-Because of sunlight in the lake happens evaporation and evaporation creates water vapor. Then happens condensation process in which water vapors turns into clouds.

6. How can a cloud turn into groundwater?

-First happens precipitation process, it causes run-off. Then water goes underground by infiltration.

Essential Questions 
1. How are rock, carbon and water cycles connected to hydrosphere, lithosphere, biosphere and atmosphere? 

Hydrosphere-is the water layer of Earth.

Hydrosphere and carbon cycle connected to each other by photosynthesis, because plants use groundwater in photosynthesis process. Hydrosphere and rock cycle connected to each other
by erosion and weathering.

Lithosphere-Land, underground.

Most of the processes in rock cycle happens underground. Creation of metamorphic rock and sedimentary rock, melting of metamorphic rock. Lithosphere and water cycle connected to each other by infiltration and underground water. Lithosphere and carbon cycle connected to each other by fossil and fossil fuels.

Atmosphere-air that covers the Earth.

Atmosphere and carbon cycle connected to each other by CO2 emissions, CO2 and O2. Atmosphere and water cycle connected to each other by evaporation, water vapors, precipitation and transpiration. Atmosphere and rock cycle connected to each other by weathering and eruption.

Biosphere-Living world.

Biosphere and rock cycle connected to each other by eruption, because eruption releases CO2 for plants. Biosphere and water cycle connected to each other by transpiration. Biosphere and carbon cycle connected to each other by consumers, decomposers and producers.

2. How are the three cycles (rock, carbon & water) connected to each other?
- Carbon cycle connected to rock cycle by fossil because fossil is a type of sedimentary rock (Coal).
Carbon cycle and water cycle also connected to each other. In photosynthesis plants use groundwater that is in water cycle. Rock cycle and water cycle connected to each other by precipitation, weathering and erosion.
