This is the core, or center, of an atom.

What is a nucleus?

200

This is a molecule made of 1 carbon atom and 1 oxygen atom.

What is Carbon Monoxide?

200

These 2 elements combined create water or H2O.

What are Hydrogen and Oxygen?

200

This is the process of breaking down rocks.

What is Weathering?

200

This is the process by which rocks or particles of rocks are transported from their original location and deposited elsewhere.

What is erosion?

400

These substances surround the central nucleus

What is an electron?

400

These molecules is made up of 2 hydrogen atoms and 1 oxygen atom.

What are water molecules?

400

This body of water holds roughly 97% of all water on Earth.

What is the ocean?

400

This is the deterioration of stone as a result of chemical reactions.

What is Chemical Weathering?

400

This is the most common form of erosion.

What is Water Erosion?

600

This 1 of 2 substances that make up an atom's nucleus?

What is a proton?

600

This substance is a molecule created by a combination of sodium and chlorine.

What is salt?

600

This is the physical, chemical, and biological characteristics of water.

What is water quality?

600

This is a type of rain that forms through air pollutants such as sulfur dioxide. 

What is acid rain?

600

This form of erosion can only occur on smaller sediments such as dust and sand.

What is Wind Erosion?

800

This is the other 1 of 2 substances that make up an atom's nucleus?

What is a neutron?

800

This gas is represented by this chemical formula:

CO2

What is carbon dioxide?

800

This is water that has little to no salinity.

What is Freshwater?

800

This is a type of weathering caused by animals and plants.

What is biological weathering?

800

This is the least common form of erosion and only occurs in certain places on earth.

What is Ice Erosion?

1000

These are what hold together molecules.

What are chemical bonds?

1000

This molecule, also called a sucrose molecule, is represented by this chemical equation:

C12H22O11

What is a sugar molecule?

1000

This is water with substances dissolved in it that lower it's pH.

What is acidified water?

1000

This is the process by which rocks break down into smaller pieces without changing their chemical composition.

What is Physical Weathering?

1000

This process occurs when a rock's chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.
