What is matter?
Anything that has mass and takes up space.
Define evaporation
Evaporation occurs when a liquid becomes a gas.
What are the three kinds of rocks?
Igneous, metamorphic and sedimentary
What is a fossil?
Fossils are the preserved remains of plants and
animals that were once living on Earth.
What is paleontology?
Paleontology is the study of the history of the earth based on fossils.
A solid ________ its shape unless __________ is applied
A solid holds its shape unless force is applied
Define condensation
Condensation occurs when a gas becomes a liquid.
What is a rock?
A rock is a solid material that is a lump of minerals that grow or are fused together.
What is the rock cycle?
The rock cycle is used to describe how rocks are formed, how
they break apart, and how they reform into other rocks.
What is thermal energy?
Thermal energy is the energy in an object due to
the movement of its molecules and atoms.
A liquid is a form of matter that has no __________ ________________.
A liquid is a form of matter that has no defined shape.
Define sublimation
Sublimation occurs when a solid becomes a gas.
What is an igneous rock?
Igneous rocks have formed through the cooling and hardening of lava and magma.
What is a mineral?
A mineral is created by nature and forms the Earth’s rocks, and soils.
___________: are the smallest unit that matter can be divided into.
Atoms: are the smallest unit that matter can be divided into.
particles in gases move _________.
particles in gases move freely.
Define deposition
Deposition occurs when a gas becomes a solid.
What is a sedimentary rock?
Sedimentary rocks are made when sand, mud and pebbles
get compressed in layers, which eventually turn to rock.
What is an example of a metamorphic rock?
Marble
Name all 5 physical properties of matter
Lustre, opacity, hardness, magnetism, colour
A gas __________ to fit the volume of the container it is placed in.
A gas expands to fit the volume of the container it is placed in
Give one example of sublimation and one example of deposition
Sublimation: dry ice (solid turns to gas)
Deposition: Frost forms when warm, moist air comes into contact with cold surfaces. (gas to solid)
What is a metamorphic rock?
Metamorphic rocks are formed when other rocks are
exposed to high temperature and pressure.
What is the hardest mineral and what number on the MOH scale is it? What is the softest and the number?
Hardest: diamond at a 10
softest: talc at a 1
What are the physical properties of minerals?
Magnetism, transparency, hardness, lustre, streak
