Sedimentary Rocks
These are rocks that are made of dirt, shells, and other things collect and get pressed together.
What is sedimentary rock?
These rocks are created when igneous or sedimentary rocks are changed into another form of rock by heat and pressure.
What is metamorphic rock?
These rocks are formed by cooled and hardened magma.
What are igneous rocks?
This is something that is a solid, inorganic, found naturally in Earth, has a crystal shape, and my be an element or a compound.
What is a mineral?
Crystallization and cooling of magma creates this type of rock.
What is Igneous Rock?
This is the test used to determine a mineral's hardness.
What is Moh's Scale of Hardness?
Plant Fossils are often these type of fossils
What is imprint fossils?
This is rock made from salt water through chemical formation.
What is Halite?
This means to force out.
What is extrusive?
This is what you call the hardening of rocks from lava and magma. The faster it cools the less time the minerals have to form these. 2 words.
What are crystallization and crystals?
These are made from different minerals.
What are rocks?
Weathering, erosion and deposition creates this type of rock.
What is sedimentary rock?
This describes how light reflects off a mineral.
What is Luster?
The most common type of fossil is formed by this.
What is permineralization?
This type of formation of sedimentary rock involves wind and rain breaking apart rocks into smaller pieces that get cemented together. It is the most common way sedimentary rocks are formed.
What is mechanical formation?
This takes place in small areas where hot lava touches the surface of rocks, causing them to change into a new rock
What is contact metamorphism?
When lava reaches the earth's surface and is cooled and hardened, this type of igneous rock is formed.
What is extrusive?
Carbon makes up this mineral.
What is a diamond?
Extreme heat and pressure deep below the earth's surface creates this type of rock?
What is metamorphic rock?
This is when a mineral breaks unevenly or in curved pieces.
What is fracture?
A dinosaur footprint is an example of this.
What is a trace fossil?
This is the breaking down of rocks, the transportation of rock and the settling of rocks in that order.
What is weathering, erosion and deposition?
This takes place when large areas of rock are buried in an earthquake, causing the rock to get squeezed and heated until it changes into a new type of rock.
What is regional metamorphism?
This is the most common intrusive rock.
What is granite ?
A specific mineral that is a compound always has the same ratio or different combinations of the same elements.
What is the same?
When sedimentary and metamorphic rock melts it turns into this.
What is magma?
This describes a mineral that breaks into even, flat sheets.
What is cleavage?
This is the result of an insect getting trapped and preserved in a sticky plant material.
What is an amber fossil?
This means " made from rock pieces"
What is clastic rock?
Metamorphic rocks are compared with these. The properties of the new rock may be similar but the biggest difference is shape, color, and overall appearance.
What are parent rocks?
This is the most common extrusive rock.
What is basalt?
A mineral that glows under UV light has this quality.
What is fluorescence?
These are five ways water can cause weathering.
What are rain, rivers, ocean waves, ice and glaciers?
If this procedure produces a fizzing reaction, the mineral probably contains calcite.
What is an acid test?
These are 3 things you can tell about the past by studying fossils.
What the weather was like in the past.
What type of food animals were able to eat in the past.
Where water was in the past.
The structure and function of animals that lived long ago.
