Deltas typically form at mouths of rivers when they are entering large water bodies. Why does it form here?

Water slows as it enters larger bodies and deposits sediments

What formed this "V" shaped valley in the Grand Canyon?

Rivers weathering and eroding away rock layers

The world's older mountain ranges (Appalachian) are typically shorter than newer mountain ranges (Himalayas). Why?

The older mountains have gone through more weathering and erosion

What are the factors that cause weathering, erosion, and deposition?

Surface Water, Groundwater, Ocean Waves, Wind, Ice, Gravity

Which Florida landform is most responsible for protecting the coastline from erosion? How does it do this?

Sand Dunes. They are barriers to storm surge and water erosion

How do Florida's rivers differ from those of states with more mountains?

Florida's rivers are shallower and flow more slowly causing less erosion

What formed this "U" shaped valley in the Himalayas?

Glaciers weathering and eroding away rock layers

Why is igneous rock the most common rock found on volcanic islands and around the mid-ocean ridge?

Igneous rocks form by magma/lava cooling. Both locations contain these

Obsidian is an example of igneous rock. Where can most igneous rocks be found?

Near volcanoes and mid-ocean ridges from magma cooling

How are most lakes in Florida formed? How does this make them different from lakes in other states?

Sinkholes. They are shallower than lakes that form in mountain depressions

Lapis Lazuli is an example of metamorphic rock. Where can most metamorphic rocks be found?

Deep inside the Earth where heat and pressure are

Rock Salt is an example of sedimentary rock. Where can most sedimentary rocks be found?

All over Earth as they are layered due to compaction and cementation

How do plants affect the rate of erosion?

The decrease the rate of erosion by holding soil in place.

Describe the process involved in forming igneous rock.

Melting of rocks back into magma then cooling of magma/lava

How has the melting and forming of glaciers on Earth impacted Florida?

Melting of glaciers makes sea levels rise and causes coast to be underwater

Describe the process involved in forming metamorphic rock.

One kind of rock changes into a new rock from immense heat and pressure

Describe the process involved in forming sedimentary rock.

Weathering/Erosion of rocks into sediment then compaction and cementation

1
Deltas typically form at mouths of rivers when they are entering large water bodies. Why does it form here?
Water slows as it enters larger bodies and erodes away the existing land
Water quickens as it enters larger bodies and deposits sediments
Water slows as it enters larger bodies and deposits sediments
Water quickens as it enters larger bodies and erodes away the existing land
2
What formed this "V" shaped valley in the Grand Canyon?
Glaciers weathering and eroding away rock layers
Rivers depositing rock layers
Rivers weathering and eroding away rock layers
Glaciers depositing rock layers
3
What type of rock is likely to form after many years of sand, silt, and clay being pressed together over many years?
Sedimentary
Metamorphic
Igneous
Magma
4
The world's older mountain ranges (Appalachian) are typically shorter than newer mountain ranges (Himalayas). Why?
The older mountains have gone through more weathering and erosion
The newer mountain ranges are bunching up due to convergent plates
The newer mountain ranges have had more deposition
The older mountain ranges are spreading apart due to divergent plates
5
What are the factors that cause weathering, erosion, and deposition?
Surface Water, Groundwater, Ocean Waves, Wind, Ice, Gravity
Surface Water, Groundwater, Ocean Waves, Wind, Ice, Plants
Surface Water, Ocean Waves, Wind, Ice, Gravity

6
Which Florida landform is most responsible for protecting the coastline from erosion? How does it do this?
Sand Dunes. They are barriers to storm surge and water erosion
Sand Dunes. They build up by wind deposition of sediments
Sand Dunes. Plants grow on them and help prevent erosion.
Sand Dunes. They protect against ice erosion
7
How do Florida's rivers differ from those of states with more mountains?
Florida's rivers are shallower and flow more slowly causing less erosion
Florida's rivers are deeper and flow more quickly causing more erosion
Florida's rivers are shallower and flow more quickly causing more erosion
Florida's rivers are deeper and flow more slowly causing less erosion
8
What formed this "U" shaped valley in the Himalayas?
Rivers weathering and eroding away rock layers
Rivers depositing rock layers
Glaciers weathering and eroding away rock layers
Glaciers depositing rock layers
9
Why is igneous rock the most common rock found on volcanic islands and around the mid-ocean ridge?
Igneous rocks form by magma/lava cooling. Both locations contain these
Igneous rocks form under heat and pressure which happens at both locations
Igneous rocks form by water and volcanoes breaking down sediments.
10
Obsidian is an example of igneous rock. Where can most igneous rocks be found?
Only near volcanoes from magma cooling
Near volcanoes and mid-ocean ridges from magma cooling
All over Earth as they are layered due to compaction and cementation
Deep inside the Earth where heat and pressure are
11
How are most lakes in Florida formed? How does this make them different from lakes in other states?
River Erosion. They are deeper than lakes that form in mountains
Sinkholes. They are shallower than lakes that form in mountain depressions
Sinkholes. They are deeper than lakes that form in mountain depressions
River Erosion. They are shallower than lakes than form in mountains
12
Lapis Lazuli is an example of metamorphic rock. Where can most metamorphic rocks be found?
All over Earth as they are layered due to compaction and cementation
Only near volcanoes from magma cooling
Deep inside the Earth where heat and pressure are
Near volcanoes and mid-ocean ridges from magma cooling
13
Rock Salt is an example of sedimentary rock. Where can most sedimentary rocks be found?
Deep inside the Earth where heat and pressure are
Near volcanoes and mid-ocean ridges from magma cooling
All over Earth as they are layered due to compaction and cementation
Only near volcanoes from magma cooling
14
How do plants affect the rate of erosion?
They increase the rate of erosion by breaking up soil.
The decrease the rate of erosion by holding soil in place.
They decrease the rate of erosion by breaking up rocks.
They increase the rate of erosion by root wedging.
15
Describe the process involved in forming igneous rock.
Melting of rocks back into magma then cooling of magma/lava
Weathering/Erosion of rocks into sediment then compaction and cementation
One kind of rock changes into a new rock from immense heat and pressure
16
How has the melting and forming of glaciers on Earth impacted Florida?
Melting of glaciers makes sea levels rise but does not impact the coast
Melting of glaciers makes sea levels rise and causes coast to be underwater
Melting of glaciers causes more deposition of sediments adding to the coast
Formation of glaciers makes sea levels fall and exposes more of the coast

Describe the process involved in forming metamorphic rock.
One kind of rock changes into a new rock from immense heat and pressure
Melting of rocks back into magma then cooling of magma/lava
Weathering/Erosion of rocks into sediment then compaction and cementation
