A plant or animal remain that is most commonly found in sedimentary rocks
What is a fossil
100
the process of a rock being changed by heat, pressure or both
What is metamorphism
100
Melted rock has to do this before it can become an igneous rock
What is cool and harden
100
a rock that forms when melted rock cools either inside the Earth or on Earth's surface and becomes solid
What is igneous rock
100
a naturally formed solid that is usually made up of one or more types of crystals
What is a rock
200
The process of rock particles settling in layers in their new location, biggest pieces first
What is deposition
200
A metamorphic rock forms over a long period of time from a parent rock that receives these two forces
What are heat and pressure
200
The specific type of igneous rock is determined by the the minerals it is made of and what else
What is size of mineral crystals
200
a rock that forms when loose material, such as rock pieces, plant/animal remains, dirt, sand, soil, settles in layers and gets pressed and glued together
What is sedimentary rock
200
a force applied to a surface
What is pressure
300
The process of layers of sediment getting pressed together and forming rocks over time
What is compaction
300
Heat and pressure can cause these to form in rocks in place of older ones
What are new minerals
300
forms from magma cooling slowly within the Earth
What is intrusive igneous rock
300
a rock that forms when an existing rock, called a parent rock, gets heated and receives pressure over a long period of time
What is a metamorphic rock
300
melted rock within the Earth
What is magma
400
The process of minerals crystallizing to glue sediment pieces together
What is cementation
400
In this size area, rocks are buried, pressed together, bent and heated
What is a large area
400
forms from lava cooling quickly on Earth's surface
What is extrusive igneous rock
400
this rock could form after a rock has broken down into loose particles at Earth's surface
What is sedimentary rock
400
material such as rocks, minerals, and plant and animal pieces that settle out of water or air
What is sediment
500
a sedimentary rock composed of ocean organisms' shells and skeletons that get deposited in layers on the ocean floor, compacted and cemented into rock
What is limestone
500
When rocks move past each other in an earthquake and are subjected to high pressures, this size area of metamorphic change can happen
What is a small area
500
This determines whether a rock is intrusive or extrusive
What is where it is formed
500
this rock can form after magma or lava cools
What is igneous rock
500
the set of natural processes that form, change, break down, and re-form rocks
