Name the steps of the water cycle
precipitation, evaporation, condensation
The breaking down of rock by rain, wind, water, gravity, and at or near Earth's surface into smaller peices is called. . .
What is Weathering
A natural feature of the Earths Surface that form over time
Land forms
What makes the seasons?
The tilt of the Earth on its Axsis.
The primary cause of seasons on Earth is the tilt of Earth's axis as it revolves around the Sun; when the Northern Hemisphere tilts towards the Sun, it experiences summer, while when it tilts away, it experiences winter.
What time is it when the sun is directly overhead?
12:00 Noon

What breaks down rock by weathering it?
What is wind, water, & gravity, organisms
Describe how weathering and erosion work together to shape the Earth's surface.
Weathering breaks down the rock and erosion transports the particles to shape and reshape the landscapes.
The movement of the Earth's Plates.
Plate Tectonics
Name two renewable resources of natural energy
Wind, water, sunlight
The process of moving soil and rock from one location to another to for new landforms.
erosion
Rapid decrease in the number of species in a short period of time
Mass Extinction
What are the significance of fossils when understanding the earth's history.
They give us evidence of past life and may give us a timeline if we studey where they are in the sedimentary layers of rock.
This is the amount of time Earth's revolution takes
365.4 days

Rock formed from layers of sediment such as the Grand Canyon.
Sedimentary Rock
_______ is when the wind/water/glacier drops the material they are eroding
What is deposition
What letters can you use to restate the planets in order?
M,V,E,M,J,S,U N
What causes a day and a night?
We experience day and night because the Earth rotates on its axis, meaning as it spins, one side faces the sun experiencing daytime, while the other side faces away from the sun experiencing nighttime; this rotation takes about 24 hours to complete, making one day and one night.
