Rock cylce
What are the three main types of rocks?
igneous, metamorphic, sedimentary
What is thermal energy?
Thermal energy is the energy of heat.
What is plate tectonics?
Plate tectonics is the movement of Earth’s surface plates.
What is natural selection?
Natural selection is the process where organisms with helpful traits are more likely to survive and reproduce.
What is evolution?
Evolution is the change in living things over long periods of time.
How is sedimentary rocks formed
sedimentary rocks are formed when sediment is compressed into layers and harden
What happens to an object when it loses heat?
It cools down.
What layer do tectonic plates float on?
The mantle.
Who came up with the idea of natural selection?
Charles Darwin
What is a fossil?
A fossil is the preserved remains or traces of a living thing from long ago.
What is deposition
Is the process by which eroded rocks and sediment build up and settle somewhere new
Which has more thermal energy: a hot cup of coffee or a cold glass of water?
The hot cup of coffee.
What natural disaster is commonly caused by plate movement?
Earthquakes.
Why is variation important?
Variation gives organisms different traits, which helps some survive better than others.
What is a species
A species is a group of organisms that can reproduce and have offspring.
what are intrusive rocks
form when magma cools slowly beneath the earth surface
What is convection?
Convection is heat transfer through moving liquids or gases.
What causes plate movement?
Heat from inside Earth creates movement in the mantle.
What is a trait?
A trait is a characteristic or feature of an organism, like fur color or beak shape.
What is adaptation
An adaptation is a trait that helps an organism survive in its environment.
what are extrusive rocks
form when lava cools quickly on or near the surface
What is radiation?
Radiation is heat transfer through waves
What is a fault?
A crack in Earth’s crust where plates move.
What happens to helpful traits over time?
Helpful traits become more common in a population over time.
What is a species?
A species is a group of organisms that can reproduce and have offspring.
