Landscapes Day 2

Agents of Erosion

How does the bedrock beneath a mountain and plateau differ?

To the right, draw the drainage pattern for water going down a mountain

 

Name the five agents of erosion:

Aim, Learning Target & Agenda

AIM: What causes the landscape to

change over time?

Learning Target: I can list the agents of erosion and

explain how each type changes the landscape.

Agenda: Do Now Mini Lesson Practice Problems

Mini Review

What’s makes a region a landscape? What has to be similar?

Mini Review

What’s makes a region a landscape? What has to be similar? shape climate The way the underlying rocks are

positioned

Mini Review

When we talk about shape we’re often talking about ELEVATION How high something above sea level

What is the name of a landscape that has high elevation and high relief? MOUNTAINS

How are Landscapes Changed?

Many landscapes are changed due to WEATHERING and EROSION

Weathering: The change in rocks that occurs

when they are exposed to conditions at Earth’s surface

Erosion: Any process that moves sediments

Conditions of Weathering (Or Agents of Erosion)

Water (precipitation) Rain Snow Ice freezing Glaciers Running water (streams, rivers, etc)

Wind

Ice

Waves

The topography of a region depends on...

the balance at any given time between forces that uplift the land and agents of erosion that wear down the land.

Depending on the COMPOSITION of rocks, certain rocks RESIST erosion.

Water erodes the mountainV-shaped valley

Wind and Waves deposit sand on beach

Waves and high/low tide moves sand, etc onto thelandmass

Water from highland sourceRocks erode, water rushes downhill

Water erodes the rockstarting to create a V – shaped valley
