MINERAL PROPERTIES
This property describes how shiny or dull a mineral looks.
Luster
This type of rock forms from cooling magma below Earth’s surface.
igneous rock
What happens to magma to turn it into rock?
it cools and hardens
Earth’s atmosphere is made up of this.
gases (air)
Most of Earth’s water is found here.
oceans
This test involves rubbing a mineral on a plate to see its powder color.
streak test
This rock type is most likely to form at the bottom of oceans or lakes.
sedimentary rock
What two things are needed to change a rock into metamorphic rock?
heat and pressure
What is the main job of the ozone layer?
protecting Earth from harmful UV rays
This is water stored underground between rocks and soil.
aquifer
Minerals must be naturally formed and NOT made by this.
humans (man-made)
This rock type is formed deep underground due to extreme heat and pressure.
metamorphic rock
What must happen to sediments before they become rock?
they are compacted and cemented together
In the water cycle, this is when water turns into vapor.
evaporation
What do we call water that falls from clouds to Earth?
precipitation
Minerals are always solid and NOT made from this type of material.
living (organic) material
This rock type forms from lava cooling on Earth’s surface.
igneous rock
What is the name of the process that moves rock pieces from one place to another?
erosion
In the water cycle, this is when water vapor cools and forms clouds.
condensation
What is a long period with little or no rainfall called?
drought
Why can color NOT always be used to identify a mineral?
because many minerals can be different colors
Which rock type is formed from pieces of other rocks being compacted together?
sedimentary rock
What is the name of the process that breaks rocks into smaller pieces?
weathering
Why is air important for living things?
it provides oxygen to breathe.
What happens during a flood?
water covers land that is normally dry.
