How are rocks DIFFERENT from minerals?
Rocks are a pure substance and minerals are all mixtures.
Rocks have no physical or chemical properties similar to minerals.
Minerals are made up of at least two rocks, but rocks are not made up of minerals.
Rocks are made up of one or more minerals, but minerals are not made up of rocks.
How can an igneous rock be transformed into a metamorphic rock?
if it is forced deep into Earth, where it melts into magma
if it is heated and put under pressure for long periods of time
if layers of sand accumulate over it and harden over a period of time
if it is exposed at the surface and is weathered over a period of time
Which of these BEST describes the concept of the rock cycle?
sedimentary rocks may be remelted several times
rocks move in circles on the earth as the earth rotates
rocks can be moved from place to place on the earth without changing
rocks are continually changing, and any type of rock may be transformed into another rock by the appropriate process

Mineral
Magma
Lava
Rock
The resistance of a mineral to being scratched is called________
Mineral
Rock
Hardness
Luster
A natural, solid mixture of minerals or grains is a ____________.
Mineral

Which statement best describes how sedimentary rocks form?
They form from molten rock, or magma.
They are squeezed under heat and pressure until new crystals form.
They form inside Earth's crust.
They form as sediment collects in layers that become stuck together.
When and how do metamorphic rocks form?
When lava is released from volcanoes, the lava cools and becomes rock.
When sediment is deposited in layers, the sediment sticks together and becomes rock.
When rock is worn away by rainfall, the particles collect on flat surfaces.
When heat and pressure act on rock, the rock changes form.
Which property describe a characteristic of a sedimentary rock?
large crystals
glassy
small crystals
layers
What is the rock cycle?
A fast process
A one-time change
The natural change of rocks over time
Formation of soil only
Why are rocks and minerals important in daily life?
Only for decoration
Only for jewellery
They provide building materials and metals
Only for farming
