Earth's Spheres
What is the biosphere?
the region where life exits on earth (plants, animals and humans)
What is step 1 in the water cycle? Explain
Water evaporates from the Earth's surface
True or false: The Earth is a very watery planet
True
Define Season
4 divisions of the year defined by daylight hours and the Earth's changing position with the sun.
What is a shadow?
the dark area behind an object that blocks light.
What is the hydrosphere?
the part of the Earth that is made up of water
What is step 2 of the water cycle? Explain
Which one of the Earth's spheres is water?
hydrosphere
Define Orientation
a position of an object
Your shadow changes during the day?
HOW (3 ways)? and WHY?
How:
1.shape (skinny to fat)
2. size (tall to short)
3. orientation (east to west)
WHY?
because the position of the sun changes during the day.
What is the geosphere?
The part of the earth that is solid (rocks, landforms) that makes up the Earth's surface.
What is the third step in the water cycle? Explain
Precipitation (Rain)
How much of Earth's water is in the ocean?
96.5%
Define the Lunar Cycle
the 4 week period during which the moon orbits earth one time.
How does the length of a shadow change during the day? (Longer/Shorter) How does the sun impact this?
Shadows are longer in the late morning and late afternoon when the sun is LOW in the sky.
What is the atmosphere?
the layer of gases surrounding Earth
Last step in water cycle. explain
Collection- where the precipitation goes
How much of the earth's surface is covered by water?
71%
Define SUN
the star at the center of the solar system around which everything else orbits; a source of light
3 Times of Day:
Morning/Sunrise: SUN is in the ______, SHADOW points ______
Noon: SUN is ________, SHADOW points _______
Afternoon/sunset: SUN is in the _______. SHADOW points _________.
1. Morning/Sunrise: sun is in the east, shadow points west
2. Noon: Sun is high in the sky, shadow points north
3. Afternoon/sunset: sun is in the west, shadow points east
How many Earth's spheres are there?
How do they interact with one another?
4
A change in one sphere affects another.
Plants (biosphere) release oxygen (atmosphere) or volcanoes (geosphere) send ash into the water (hydrosphere) all influencing life on earth
Explain the full water cycle and name the 4 steps.
1. Begins with water Evaporation from the Earth's surface.
2.Enters the atmosphere and condenses(CONDENSATION) into clouds
3. It returns to earth's surface as PRECIPITATION
4. Collection- where the precipitation and melting snow etc. go to then be evaporating again
Name 6 ways water exists on Earth
1. water vapor
2.riveres
3. lakes
4. glaciers
5. in the ground
6. in living things
7. oceans
Name the 8 phases of the moon in order
1. New
2. Waxing Crescent
3. First Quarter
4. Waxing Gibbous
5. Full
6. Waning Gibbous
7. Third Quarter
8.Waning Crescent
