space part 1and 2
the time when your part of Earth is facing away from the Sun, so it is dark outside (12 hours)
Materials that formed earth that humans use and can re-use. Examples: water, wind, sunlight, trees
Renewable Resources
matter with a definite volume but no definite shape (water)
liquid
When energy bounces off objects
Reflect
How fast or slow something moves.
speed
the time when your part of Earth is facing the Sun, so it is light outside (12 hours)
day
breaking down rocks by wind, water, ice, temperature change, and plants
Weathering
matter with a definite shape and a definite volume (ice)
solid
How high or low a sound is, which depends on how fast or slow it vibrates
Pitch
Energy from moving water that can be used to move things or make electricity.
water energy
A natural object made of rock that orbits or revolves around a planet
the moon
A property of a mineral that asks what color is it?
color
matter with no definite shape and no definite volume (water vapor)
gas
Energy that we can see, which travels in a straight line until it hits matter
Light Energy
Energy from moving air that can be used to move objects or turn turbines.
wind energy
Some objects in space have an axis that is leaning or slanted instead of straight up and down. This causes us to have seasons.
tilt
the slow process of one type of rock changing into another type of rock over and over for millions of years
the rock cycle
anything that has mass and volume
A wave motion that is quick and back-and-forth and produces sound.
Vibration
Energy in motion, kinetic (motion) and potential (position)
Mechanical Energy
an imaginary line that goes through the middle of an object from top to bottom
axis
A property of a mineral that asks how easily it can be scratched?
harness
how much space matter takes up
volume
A material that does not allow energy to transfer through it easily (like plastic, wood, or rubber).
Insulator
The path something moves, such as left, right, up, down, forward, or backward.
