What are the three types of rocks
Igneous
Sedimentary
Metamorphic
How do you break apart mock rocks.
You use picks to break the rock into pieces
What does dissolve mean?
It is when things disappear into water or liquid.
What does hardness mean?
How strong a rock is
What is calcite?
It is a mineral in many rocks
How are igneous rocks made?
Magma cools on the earth's surface.
Ho did we look at the different materials from the mock rock after breaking it into different categories.
We put the sand into water and shook it.
What is the definition of a rock?
An earth material that is made of more than one thing.
How do we test materials for hardness?
We scratch them.
What is special about calcite and how it can be identified?
Calcite makes bubbles when it is put in vinegar or any type of acid.
What are sedimentary rocks
plants, shells, dirt, mud, sand falls to the bottom of rivers and pressure makes it form into a rock
What happened when we poured water into the evaporation dish?
The water evaporated and left salt crystals.
What is a mineral?
An earth material that is made of only one thing.
What does it mean if a rock can be scratched by a lot of items?
It means the material is not very hard.
How did we test other rocks to see if there was calcite in them?
We put them in vinegar and looked for the bubbles.
How are metamorphic rocks formed?
Sedimentary rock is put under pressure and heat over a long time and turns them into metamorphic rocks.
What are different properties of rocks?
Shiny or not, color, roughness, weight, texture etc.
What is evaporation?
When a liquid goes from liquid to gas.
What is one of the hardest rocks on the planet?
What is another test we do for calcite in rocks? It happens after they have been in a vial with acid or vinegar?
You put the liquid in an evaporation dish and wait to see if there are crystals left.
