The water cycle broken down Click on image to learn more… Step 3-Sublimination Also creates water vapor (like evaporation) Ice goes directly from a solid to a vapor in sublimation. Refers to ice caps and sheets in the north and south poles. Slower process than evaporation. The water cycle broken down Click on image to learn more…

The water cycle broken down Step 4- Precipitation In this stage, the clouds (made during condensation) pour down. Why? Because of wind and temperature changes. Why? Because the air can’t hold any more water. This Photo by Unknown Author is licensed under CC BY-SA The water cycle broken down

The water cycle broken down Step 5-Transipiration Some of the rain (water) the precipitates is absorbed back into the ground and into the soil. Plant roots absorb the water in the soil. This is part of photosynthesis. Click on image to learn more… The water cycle broken down

Transpiration Water travels through the ground. The roots of the plant carry the water to the plant’s leaves. Water vapor escapes from the plant’s leaves. The water vapor goes back into the air. Label the following: The Sun Ground Moisture The Leaves The Roots The Ground

The water cycle broken down Step 6- Run-off As it rains (snows, hails, etc.), it leads to runoff. This is when water is running over the surface of Earth. Melting snow Pouring rain As the water runs down, it carries minerals and top soil with it. Runoffs also help create lakes, streams, seas, etc. The water cycle broken down

The water cycle broken down Step 7- Infiltration Some precipitation is absorbed by plants through the soil. Some precipitation helps create runoff, and lakes and streams are formed. Sometimes the precipitation moves deep into the soil. This is called infiltration. The water cycle broken down

Infiltration Click on image to learn more… The water seeps down and increases the level of ground water. It is called pure water and is drinkable. The infiltration is measured as inches of water-soaked by the soil per hour. Click on image to learn more… Infiltration

What is the carbon cycle? The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. What is the carbon cycle?

Introduction into the Carbon Cycle, click image for video

Carbon Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon.

There are 4 stages in the Carbon Cycle

Click on image to learn more…

Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Step 1

Carbon dioxide is absorbed by plants for photosynthesis Step 2

Animals feed on plants, passing carbon along the food chain Animals feed on plants, passing carbon along the food chain. Most carbon they consume is exhaled as carbon dioxide when they breathe. The animals and plants eventually die. Step 3

Dead plants and animals are eaten by decomposers and carbon in their bodies is returned to the atmosphere as carbon dioxide. In some conditions decomposition is blocked. The plant and animal material may then be available as fossil fuel in the future for combustion. Step 4
