Bellwork – Review of last week

1. Bellwork (review of layers of the Earth) 2. Notes, Landform Creation 3. Videos, Erosion 4. 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

Agenda

Objective: To discern the difference between primary and secondary landforms

Question: How are landforms created?

Landform Creation

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 Creation

Landform = a geographical feature of the Earth, created by a natural process

Landform Creation

How are landforms created?

◦ 1. Internal Process (Plate Tectonics): Example = mountains, volcanoes, islands, fault lines,

rift valleys

◦ 2. External Process Erosion Weathering Sediment Deposit

Landform Creation

Erosion = the wearing away of a solid over time by natural causes◦ Usually happens by wind, water, ice

Landform Creation

Weathering = decomposition of Earth’s materials because of direct contact with the atmosphere/chemicals

Landform Creation

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

Landform Creation

Sediment Deposit = when Earth’s particles are carried by wind, water, or ice from erosion elsewhere and left in a new place (deposited)

Tuesday

Agenda

Primary Landforms = those created through tectonic activity

Secondary Landforms = those created through erosion, weathering, or sediment deposit.

Landform Creation

Alluvial Fan : deposit formed at the bottom of a mountain, valley, or canyon from a fast flowing stream or river

Landform Creation

Valley = deep area between two mountains, carved out by glaciers or rivers

Landform Creation

Canyon: deep ravine between two cliffs carved out by a river

Landform Creation

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)

Landform Creation

Plateau/Mesa = flat topped mountain or hill, with sides carved by wind over time

Landform Creation

Continental Shelf – a part of the continental crust of a continental plate, is the edge of each continent

Landform Creation

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 *If you don’t know what a landform is, Look it up!
