Bellwork (review of layers of the Earth)
Notes, Landform Creation
Videos, Erosion
HW:
◦ Honors – explain the difference between erosion
and weatherine
◦ Standard – create a “cartoon strip” with one block
for each of the four spheres of the outer Earth.

Remember: Map Quiz on Wednesday, Quiz
2.1 next week


Objective: To discern the difference between
primary and secondary landforms
Question: How are landforms created?

4 outer spheres to the Earth
◦ Lithosphere = Earth’s crust, landforms
◦ Hydrosphere = Earth’s water
◦ Biosphere = Earth’s living things (plants, animals,
fungi, humans, etc)
◦ Atmosphere = Earth’s gasses, winds, weather

Landform = a geographical feature of the
Earth, created by a natural process

How are landforms created?
◦ 1. Internal Process (Plate Tectonics):
 Example = mountains, volcanoes, islands, fault lines,
rift valleys
◦ 2. External Process
 Erosion
 Weathering
 Sediment Deposit

Erosion = the wearing away of a solid over
time by natural causes
◦ Usually happens by wind, water, ice

Weathering = decomposition of Earth’s
materials because of direct contact with the
atmosphere/chemicals

How are Erosion and Weathering Different?
◦ Both wear away at landforms to mold them
◦ Erosion uses wind, water, or ice to move particles to
a new location, where it deposits them
◦ Weathering is a process where the particles are
gone forever, due to a chemical reaction or
decomposition

Sediment Deposit = when Earth’s particles
are carried by wind, water, or ice from
erosion elsewhere and left in a new place
(deposited)

MAP QUIZ TOMORROW, Quiz 2.1 Next
Tuesday


Primary Landforms = those created through
tectonic activity
Secondary Landforms = those created
through erosion, weathering, or sediment
deposit.

Alluvial Fan : deposit formed at the bottom of
a mountain, valley, or canyon from a fast
flowing stream or river

Valley = deep area between two mountains,
carved out by glaciers or rivers

Canyon: deep ravine between two cliffs
carved out by a river

Delta: landform at the mouth of the river,
where it flows into the ocean, where there is a
deposit of soil, sand, and rock (good for
farming)

Plateau/Mesa = flat topped mountain or hill,
with sides carved by wind over time

Continental Shelf – a part of the continental
crust of a continental plate, is the edge of
each continent

Put these landforms into the chart off the board
based on the type of landform they are:
Continental shelf
Fault
Glacier
Plateau
Volcano
Delta
Mountain
Rift Valley
River Valley
