Carbon Cycle
Water Cycle
Rock Cycle
100
Nitrogen gas makes up approximately this percentage of the Earth's atmosphere.
What is 78%?
100

The rocks and land is

What is geosphere

100
Some of the Carbon on Earth is stored in the atmosphere in this compound.
What is Carbon Dioxide?
100
Most of the water that moves through the water cycle is lifted into the atmosphere from these locations.
What are the oceans?
100
Liquid or molten rock material stored deep underground is also known as this.
What is magma?
200
In order to be useful to plants Nitrogen gas must go through this process.
What is fixation?
200

Includes all the water on the Earth

What is hydrosphere

200
During the day plants absorb Carbon Dioxide and convert it into organic Carbon through this process.
What is Photosynthesis?
200
When water vapor condenses into clouds it becomes to heavy for the clouds to support and it begins to fall in a process called this.
What is precipitation?
200
Magma that cools and hardens will form this type of rock. Some examples of this are Granite, Basalt and Obsidian.
What is Igneous rock?
300
These organisms in the soil play a major part in the fixation of Nitrogen?
What are bacteria?
300

The cryosphere is consisted of 

What is all the ice on the planet?

300
During photosynthesis Carbon Dioxide is taken into plants and Oxygen gas is expelled into the atmosphere while this is stored within the plants.
What is Carbon?
300
Precipitation that hits the surface and does not seep into the ground will attempt to move into areas that will transport it. This process is called.
What is run off?
300
When rocks are uplifted to the surface they are weathered and eroded away. The remaining particles will be cemented and compacted to form this type of rock.
What is Sedimentary rock?
400
Farmers will often use Nitrogen compounds for this purpose.
What is fertilizer?
400

What  is Earth’s densest atmospheric layer?

What is troposphere

400
As humans and animals breathe we take in Oxygen gas and release Carbon Dioxide gas in a process known as this
What is respiration?
400
As plants absorb groundwater into their roots the sunlight will heat up the atmosphere and cause some of this water from plants to be turned back into water vapor in a process called.
What is transpiration?
400
Rocks that experience a great deal of heat and pressure could undergo a transformation as they become this type of rock.
What are Metamorphic rocks?
500
These are at least 2 examples of compounds that are used by plants after the process of Nitrogen fixation.
What are Ammonium, Nitrates and Nitrites?
500

Name two of the spheres in the atmosphere

What are troposphere, stratosphere, mesosphere, or thermosphere

500
The primary way the Carbon is returned back to the atmosphere is through the burning of these.
What are fossil fuels?
500
All of the fresh water that does not run off into rivers, streams and lakes will attempt to seep into the ground in a process called.
What is infiltration?
500
Much of the energy from the rock cycle is caused by processes that occur deep underground in Earth's interior. This driving process for the rock cycle is called this.
What is mantle convection?
