A natural phenomenon by which all things with mass are brought toward the ground.
What is GRAVITY.
What does humidity tell us about the air?
Humidity tells us the amount of water in the air.
What cause the water to evaporate in the water cycle?
What is THE HEAT FROM THE SUN?
Earth: Mountains, Hills, Canyons
What is GEOSPHERE?
A puddle disappears after sitting in the Sun. Where did the water go?
The water evaporated. The Sun provided energy that caused the liquid water in the puddle to change into water vapor and rise into the atmosphere.
A model describing how water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization and precipitation as well as downhill flows on land.
What is THE WATER CYCLE.
If the temperature is warm, how much water vapor can it hold?
What is A LOT OF WATER VAPOR?
How do plants add water to the atmosphere?
What is TRANSPIRATION?
The layer of gas surrounding earth.
What is ATMOSPHERE?
After a storm, water flows down a hill and into a stream. What is happening to the water?
The water is moving across the land because of gravity. This is called runoff. The water flows downhill and collects in streams, rivers, lakes, or oceans.
The water found underground in the cracks and spaces in soil, sand, and rock.
What is GROUNDWATER.
What is the difference between relative humidity & dew point?
Relative humidity is the percentage of water vapor in the air (moisture) and Dew Point is the temperature at which the air becomes filled with water vapor.
What are two things that can happen to water right after it reaches the ground?
What is SURFACE RUNOFF or GROUNDWATER?
Life: Animals, humans, plants
What is BIOSPHERE?
A student notices that the outside of a cold glass becomes covered with water droplets. Where did the water come from?
The water came from water vapor in the air. When the water vapor touched the cold glass, it cooled and condensed into liquid water droplets on the outside of the glass.
The temperature at which vapor, such a smoke or fog, begins to condense and form dew.
What is DEW POINT.
What happens when the water vapor rises and cools to its dew point?
The water vapor begins to condense and form a cloud.
How does water get back to Earth's surface after forming clouds
What is PRECIPITATION?
What does hydrosphere mean?
Explain how the Sun, evaporation, condensation, and precipitation work together in the water cycle.
The Sun provides energy that causes water to evaporate from Earth's surface. As water vapor rises into the atmosphere, it cools and condenses into tiny water droplets that form clouds. When the droplets become large and heavy enough, they fall back to Earth as precipitation, such as rain, snow, sleet, or hail.
A measurement of water vapor in the air, compared to how much there could be.
What is RELATIVE HUMIDITY.
If the temperature is 50°F and the dew point is 48°F, is the air moist or dry?
Air is very moist and close to saturation
How do clouds form?
Water evaporates into the atmosphere, as it rises the temperature cools and reaches the dew point condensing creating a cloud.
What process of the water cycle is hydrosphere to atmosphere?
What is EVAPORATION?
Why can a desert still have water vapor even though it is very dry?
A desert can still have water vapor because water is constantly evaporating from sources like soil, plants, and small amounts of surface water. Even though deserts are dry, the air can still contain some water vapor.
