Landforms and agents
What is the main agent for a Delta?
Water
What does WED stand for?
Weathering
Erosion
Deposition
What is the difference between a rapid change and a slow change?
Rapid change- quickly
Slow change- millions of years
A large, slow moving mass of ice
Glacier
Which landform is a result of rapid changes to Earth's surface?
a. U-shaped Valley
b.Mountain Range
c. Volcanic Island
c. Volcanic Island
What are the 3 agents?
wind
water
ice
Explain the processes of WED:
weathering= breaks
erosion= moves
deposition= drops to new location
After a volcano erupts what does the Lava do to form new land
Lava cools and hardens
Hills of sand created by the wind depositing sand in a new location
Sand Dune
Which statement correctly describes how a landform is formed?
a. A canyon is formed by a glacier weathering and eroding sediments.
b. A sand dune is formed by wind depositing sediments.
c. A V-shaped valley is formed by wind depositing sediments.
b. A sand dune is formed by wind depositing sediments.
What is the main agent for a canyon?
water
How many continents are there?
7 continents
True or false:
One benefit of Volcanoes is that it can form new land
true
A physical feature on the surface of the earth
Landform
How is the formation of sand dunes different from the formation of deltas?
a. Sand dunes are formed by wind erosion and deposition. Deltas are formed by water erosion and deposition.
b. Sand dunes are formed by water erosion and deposition. Deltas are formed by ice erosion and deposition.
c. Sand dunes are formed by ice erosion and deposition. Deltas are formed by wind erosion and deposition.
a. Sand dunes are formed by wind erosion and deposition. Deltas are formed by water erosion and deposition.
What is the main agent for Sand Dunes
Wind
What are tectonic plates and what can they cause?
Tectonic plates are large, irregularly shaped slabs of solid rock that move on the Earth's surface.
They can cause Earthquakes to happen.
Why are Volcanoes harmful to the environment?
Name 3 examples
Eruptions are destructive:
Can kill plants, animals, people
Destroys homes and habitats
Cause pollution
An area between two cliffs that form due to Erosion from a river
Canyon
The energy carried by fast-moving rivers erodes the riverbed and banks. Over a period of time, the river’s course is lowered hundreds or even thousands of feet, forming a gorge-like landform. Which landform is created when a river cuts through the land?
a. A lake
b. A flood plain
c. A sand dune
d. A canyon
d. A canyon
What is the difference between a U-shaped Valley and a V-shaped Valley?
U-shaped= ice
V-shaped= water
What are the four layers of the Earth?
And
Which layer are Landforms located at?
4 layers:
Crust, mantle, outer core, and inner core
Landforms: located on the crust
What is the difference between Magma and Lava?
Magma- inside
Lava- Outside
Forms from deposited sediments at the mouth of a river
Delta
Canyons and mesas are two landforms found in the western part of the United States. Which statement best describes how canyons and mesas are similar?
A Both were formed by slow-moving glaciers.
B Both were formed by erosion by wind and water.
C Both were part of a mountain that was weathered by ice.
D Both were part of a desert that was reshaped by a flood.
B Both were formed by erosion by wind and water.
