Unit 1 Test
- Earth Structure
- Earth Systems
- Geosphere (Earth’s solid body)
- Atmosphere (layers of gases surrounding Earth)
- Biosphere (all of Earth’s living things)
- Cryosphere (all of Earth’s frozen water)
- Hydrosphere (all of Earth’s liquid water)
- Geosphere (Earth’s solid body)
- How Earth was Formed
- - The nebula shrank and flattened into a disk and the disk began to rotate and
then the sun formed from the densest materials in the center of the disk.
- - Planets take shape from the remaining bits of material
- - Earth formed as GRAVITY pulls particles together
- - Early planets were unevenly shaped.
- - gravity pulled in all the irregular bumps making Earth an imperfect sphere (wider at the equator and
flattened at the poles)
- - The nebula shrank and flattened into a disk and the disk began to rotate and
then the sun formed from the densest materials in the center of the disk.
- Earth's Layers
- Continental Crust
- Oceanic Crust
- Uppermost Mantle
- Lithosphere
- Asthenosphere (plastic layer)
- Upper mantle
- Lower mantle
- Outer core (only liquid layer)
- Inner core (solid because pressure outweighs the effect of temperature.)
- Continental Crust
- Earth Systems
- Types of Rocks/ Rock Cycle
- 3 Main Types of Rocks
- Igneous
- Sedimentary
- Metamorphic
- Igneous
- Materials In Rock Cycle
- Magma
- Sediment
- Metamorphic Rock
- Igneous Rock
- Sedimentary Rock
- Magma
- Processes in Rock Cycle
- Melting
- Cooling/Crystalization
- Extreme heat/pressure
- Weathering/erosion
- deposition/compaction/cementation
- Melting
- How Each Rock is Formed
- Igneous Rock
- It must be melted into magma and cooled/crystalized either on Earth’s
surface or in Earth’s interior.
- It must be melted into magma and cooled/crystalized either on Earth’s
surface or in Earth’s interior.
- Metamorphic Rock
- The rock must be in earth’s interior and exposed to extreme
heat and pressure, but not enough heat to fully melt the rock
- The rock must be in earth’s interior and exposed to extreme
heat and pressure, but not enough heat to fully melt the rock
- Sedimentary Rock
- The rock must be weathered and eroded into sediments. Those
sediments will be deposited, compacted, and cemented.
- The rock must be weathered and eroded into sediments. Those
sediments will be deposited, compacted, and cemented.
- Igneous Rock
- 3 Main Types of Rocks
- Weathering/Erosion/Deposition
- Weathering, Erosion, and Depostition Vocab
- Weathering
- The mechanical and chemical processes that change objects on Earth’s surface over time
- The mechanical and chemical processes that change objects on Earth’s surface over time
- Erosion
- The removal of weathered material from one location to another.
- The removal of weathered material from one location to another.
- Depostion
- The laying down or settling of eroded material
- The laying down or settling of eroded material
- Weathering
- Mechanical And Chemical Weathering
- Mechanical Weathering
- Physical processes that naturally break down rocks into
smaller pieces (ice wedging, abrasion, animals, plants)
- Physical processes that naturally break down rocks into
smaller pieces (ice wedging, abrasion, animals, plants)
- Chemical Weathering
- A process that changes the materials that are part of a rock into
new materials. (dissolving of minerals in water, oxidation, acid rain)
- A process that changes the materials that are part of a rock into
new materials. (dissolving of minerals in water, oxidation, acid rain)
- Mechanical Weathering
- Agents Of Erosion
- Wind
- Water
- Glaciers
- Gravity
- Wind
- Constructive/Destructive Processes
- Constructive processes: build up features on Earth’s surface (ex: deposition)
- Destructive processes: tear down features on Earth’s surface (ex: weathering)
- Constructive processes: build up features on Earth’s surface (ex: deposition)
- Weathering, Erosion, and Depostition Vocab
