Water Cycle Study Guide

Label the following arrows with Label the following arrows with the words:

gaining or losing thermal energy: condensation, evaporation, freezing, melting

GAS GAS

LIQUID LIQUID

SOLID SOLID

Give an example of water as a solid – ______; liquid – ______; gas- ______

_____ of Earth is covered by water. ______ of Earth’s water is saltwater.

______ of our freshwater is frozen

The driving force of the water cycle is the ______. The adding and taking away of ______keeps the water in a constant cycle.

When clouds become full, they will release moisture in the form of rain, snow, sleet, or hail. This is called ______. Plants also release water into our atmosphere in the process called ______.

When the precipitation falls onto the land, if the land is porous (lots of small opening), the water will seep into the ground. This is know as ______or ______.

If the land is over saturated with water or impermeable, the water will______.

______- means the land will allow water to pass through it.

______ - means the land will NOT allow water to pass though it.

Our aquifers are water that is ______ the ground. This water has been ______ as it slowly percolates down into the Earth. It is naturally filtered by the layers of ______it travels though. Underneath the water in the aquifer is a solid piece of ______ bedrock. This holds the water from infiltrating further. The top of the water in an aquifer is called the ______. Our aquifers are refilled or recharged by ______. The more precipitation, the more our levels of ground water will ______.

Atomopshere

Different layers of the atmosphere surround our planet. Starting at the Earth’s surface and working out, the layers are:

______

The different layers of the atmosphere are due to______. The further you travel from Earth, the less the ______ pull. So the layers of the Earth closer to our surface are ______because gravity pulls on the air particles and keeps them closer to Earth.

Composting

Composting is taking biomass such as grass clippings, leaves, and potato peelings and letting them ______in a pile. ______ is beneficial because it keeps this biomass from filling up our landfills. Instead, we are able to use it to enrich our soils after it has decayed. Decomposers such as ______and______ move in, which help the compost break down and decay. Decay is a ______ property. With chemical properties, you must get a ______ to observe the chemical properties.

Scientific Method

.

If we were to make a graph of the above information, we would use our hint (DRY MIX) to help us.

On the X-axis we would put the ______.

On the Y-axis we would put the ______.
