100

The energy of the moving molecules

What is Thermal Energy

100

State of matter where particles are moving freely at a medium speed in a close fluid group. 

What is Liquid

100

The form in which matter exists

What is the State of matter

100

The acting that move water either up into the atmosphere or back down to/into the earth.

What is the water process 

100

State of matter where particles more slowly, vibrating in place, and are close in fixed positions.

What is Solid

200

State of matter where particles move freely at a fast speed and are spread far apart. 

What is Gas

200

How close together or far apart atoms/molecules are from each other. 

What is Relative spacing

200

A single particle of a substance made from two or more atoms. 

What is a Molecule

200

The process where water gains energy from the sun and changes from liquid to gas.

What is Evaporation  

200

The process of liquid water flowing from underground through a plant and out into the air as a gas. 

What is Transpiration

300

a COLLECTION of objects that interact and influence one another. These objects often work together to solve or answer a problem.

The separation between a system and its environment that inputs and outputs must cross. Shows what is included and what is not.

What is the System Boundary 

400

A place where a material is stored for a period of time. 

What is Reservoir 

400

Water continuously moving between reservoirs due to the suns energy and the force of gravity.

What is a Water system

400

Water located on the surface of the earth such as Lakes and streams. 

What is Surface water

400

Water held underground in the soil or in the pores and crevices in rock. 

What is Groundwater

500

Water that falls to the ground in the form of rain, snow, sleet, etc. 

What is precipitation 

500

The process by which water moves into the soil from the ground surface. 

What is infiltration

500

Water that drains over the earth after falling as precipitation. 

What is Runoff

500

The movement of ground water which accrues very slowly 

What is Groundwater Movement 

500

The force that pulls things towards earth

What is Gravity
