The Water Cycle
What is the main source of energy for the water cycle?
The sun.
How many days does it take for the moon to go through all of its phases?
28 Days
Rain Gauge
What season is it when the northern hemisphere is tilted on its axis towards the sun?
Summer
What are three examples of condensation?
Dew, clouds, water bottle.
How long does it take for the earth to orbit around the sun?
1 Year or 365 days
What tool is used to measure the direction the wind is blowing?
Weather (wind) Vane
What season is it when the northern hemisphere is tilted on its axis away from the sun?
Winter
Explain the difference between evaporation and condensation.
Evaporation is when liquid water changes into a gas, whereas condensation is when water vapor changes into a liquid (clouds form).
What causes different parts of the Moon to be lit as it orbits around the Earth?
Reflection from the sun
What tool is used to measure heat energy?
Thermometer
It means energy is striking straight on the surface of the Earth. Areas with more direct rays will warm up more than areas with direct rays.
Describe what accumulation is.
Accumulation is when precipitation goes into the ground and/or runs off into a lake, river, ocean, or other body of water.
Describe what a waning crescent is.
A waning crescent occurs directly before a new moon. Waning means the moon is losing light and crescent is when there is more shadow than there is light.
What are weather maps used for?
They are used to make predictions about weather.
What does it mean when there are indirect rays? What happens to areas with more indirect rays?
Indirect rays means energy is striking the surface of the earth at an angle. Areas with more indirect rays will be colder than areas with direct rays.
Explain the entire process of the water cycle.
The water cycle begins with the sun. The sun heats up the Earth's oceans, rivers, and lakes and the water evaporates and turns into water vapor. This water vapor eventually turns into clouds because of condensation. Precipitation occurs when the clouds become heavy with water droplets. Rain water falls back on the earth and produces run-off.
What is the sequence of the moons phases? (List the 4 main ones)
New moon, First Quarter, Full Moon, Third Quarter Moon
How long does it take for the Earth to turn one time around its axis?
1 day?
