Pre-AP/Adv: What do landform characteristics, such as structure elevation and rock exposure, suggest about the development of landforms?

• Help determine whether destructive forces, such as erosion, produced that landform.

• Help determine whether constructive forces, such as deposition, produced that landform.

Let's review the rock types you've learned before with our favorite scientist!

Open Ended

How are erosion and deposition connected to the formation of sedimentary rocks?

San Marcos Castillo, St. Augustine

Carlsbad Caverns, New Mexico

Through the process of Chemical Weathering and Erosion, (wind, rain, snow and time) eroded away the overlying younger sediments.

THROUGH-11/4:

Landforms shaped by Erosion look:

• tall

• jagged

• with cuts in layers of rock

Over time water and ice weathered the less-resistant sedimentary rock.

Bryce Canyon National Park, Utah

Glacial Erosion produces jagged mountain peaks and U-shaped valleys.

Glacier National Park, Montana

Multiple Choice

In Florida, coastal erosion changes the size and shape of?

• Beaches

• Trees

• Mountains

• Dunes

THROUGH-11/4: Landforms created by Deposition are often

• flat

• low-lying

Alluvial Fans are an example of landforms made by deposition.

Sandbars are also mini landforms near ocean shores formed by deposition.

Tampa Bay, FL Sandbar

Multiple Choice

Which typically is NOT a depositional environment?

• delta

• mountain peak

• ocean floor

• swamp

Multiple Choice

Which landform is created by deposition?

• alluvial fan

• glacial valley

• cave

• river channel

Multiple Choice

Which landform is created by erosion?

• delta

• U-shaped valley

• sandbar

• dune

Multiple Choice

Water moving sediment down slopes and a glacier forming a U-shaped valley as it moves past mountains are examples of?

• weathering

• erosion

• deposition

• rounding
