The Water Cycle
The Sun The sun provides the energy to power the water cycleThe sun heats the upper ocean causing evaporation of liquid water into water vapor
The water vapor rises into the atmosphere and coolsThe cooled water vapor creates tiny water droplets that form clouds
When clouds become too heavy with water droplets, precipitation fallsrain sleet snow hail
Once water reaches the earth’s surface:Infiltrates the surface (soaks in) Runs across the top of the ground filling rivers, lakes, and streams (can cause erosion)
aquifer A natural underground area where large amounts of ground water collect and create an underground supply of water Amount of water stored depends on the porosity and permeability of the sediment
porosity Amount of water that a material can hold in the spaces between the pores
permeability The measure of how well an earth material can let water pass through it.
percolation The downward movement of water from the land surface into soil or porous rock. It is caused by gravity
infiltration When water enters the soil surface after falling from the atmosphere
Surface water Water located on earth’s surfaceMost US cities use surface water rivers lakes streams ponds creeks reservoirs
ground water Water located under the ground surfaceReached by using wells Cleaner and safer
pollution Any change to the environment that has a negative effect on living things Water sources are especially sensitive to pollution Burning fossil fuels can create acid rain
Discussion Questions Is there a beginning to the water cycle?What is the power source for the water cycle? How does water get into an aquifer?
The Water Cycle.
WATER EVAPORATION: Stage of water cycle when water changes from liquid to vapor (or gas)
In this presentation you will: explore the stages of the water cycle
Water on Earth is naturally recycled through the water cycle. The sun is the source of energy that drives the water cycle.
The Water Cycle Water is recycled through the water cycle.
Earth’s surface is covered mainly by water.
THE WATER CYCLE Water moves from the oceans to the atmosphere, from the atmosphere to the land, and from the land back to the oceans.
Unit 3 Lesson 1 What Is the Water Cycle?
The Water Cycle. Water is… The only common substance that exists as a solid, a liquid, and a gas. Present everywhere on Earth. In a continuous state.
Water Cycle Vocabulary
The Water Cycle By Ariane.
THE HYDROLOGIC CYCLE.

The Water Cycle What is it and how does it work?.
Water Cycle (Also known as the hydrologic cycle)
Water, water everywhere?
