Front

What is the polarity of water?

Back

Water is polar, meaning it has a partial positive charge on one side (hydrogen) and a partial negative charge on the other side (oxygen).

Front

Does weathering and erosion occur where water flows the fastest?

Back

True, weathering and erosion are more pronounced in areas where water flows rapidly.

Front

What is the transfer of heat from sand to your feet at the beach called?

Back

Conduction.

Front

How many oxygen atoms are in the ozone layer?

Back

The ozone layer is composed of three oxygen atoms (O3).

Front

Does water have a high specific heat?

Back

True, water has a very high specific heat, which means it can absorb a lot of heat before its temperature changes.

Front

What is the definition of specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is weathering?

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.
