Vocabulary
The continuous process where rocks change form
Rock Cycle
Name the 3 types of rocks that can change and become a new rock?
Igneous
Metamorphic
Sedimentary
The number of years that have passed since the rocks have been formed.
Absolute Age
What does weathering, erosion and deposition do?
weathering= breaking
erosion= moving
deposition= piling
What are the 3 regions of FL landforms?
Northern highlands
Central Highlands
Coastal lowlands
A fossil that is widely found but lived for a short period of time, used to help date rock layers.
Index Fossil
How do you form metamorphic rock?
Heat and pressure
Bottom layers are oldest top layers are youngest.
Law of Superposition
What are 4 types of chemical weathering?
1.Dissovling
2.Rust
3. Acid Rain
4. Living Organisms
An area of high flat ground
Plateau
A rule that describes what happens in nature and is always true under the same conditions.
Scientific Law
How do you form sedimentary rock?
compacted and cementation
Magma pushes into rock, it hardens. It is always younger than the other rocks around it
Intrusive
5 types of Mechanical/physical weathering?
1. Frost wedging
2. abrasion
3. plant growth
4. burrowing of animals
5. temperature
A mound of sand formed by wind erosion
Dunes
A method scientists use to find the age of rocks and fossils by measuring radioactive materials inside them.
Radioactive Dating
Process by solidification
Key word: cooling
Looks like: solid or irregular
Igneous rock
A break in the crust. Always younger than the rocks it breaks into
Fault
Is it weathering, Erosion or Deposition?
Scenario #1: Caves being formed by acid rain dissolving underground limestone.
Scenario #2: Glaciers dropping rock and sand to form terminal moraines.
#1: Weathering
#2: Deposition
A hole on the surface caused by a collapsed cavern underground.
Sinkhole
A bend in rock layers caused by pressure inside Earth.
Fold
What is the acronym (name) to remember the rock cycle order ?
Miss Metamorphic rock
Magma reaches the surface and hardens. Follows law of Superposition.
Extrusive Igneous Rock
How has weathering, erosion, and deposition shaped the landforms found in Florida?
Weathering= sinkholes and caves
Erosion= rivers and coastlines
Deposition= Beaches, wetlands and barrier islands
