Ella Schwartz Interactive Workbook- Geologic Processes

The Earth is a dynamic, ever changing planet. The interaction between the hydrosphere and the lithosphere reshapes the surface over and over again. It is a constant process of building up and tearing down. While we aren't alive for all the changes, the evidence is around us, and we use models to simulate the long term changes.

Let's explore four geologic processes in our workbook.

Caves

Use the box to Add 3D models for the main rock types dissolved to create caves.

Sandstone

Marble

Gypsum

Check out the Umanose Sea Cave found in Japan

Use the slider to see cave formation before and after.

Cave Formation

Use the four spaces to find images for the other ways caves are formed.

Coastline Erosion

Loading...

1. READ THE descriptions in the blue box.
2. Check out the 3D models.
3. move the description to the proper landform.

Loading...

WAVE-CUT PLATFORM

Loading...

These form when a sea cliff is worn back from the shore, producing a nearly level region beneath the water at the base of the cliff.

Loading...

Loading...

HEADLANDS

Loading...

Finger-shaped projections that form when cliffs of hard rock erode more slowly than the surrounding softer rock does.

Move the labels to the correct Stars on the diagram

Loading...

Large crack opened by hydraulic action.

Loading...

Loading...

The cave becomes larger.

Loading...

The arch is eroded and collapses.

Loading...

The stack is eroded forming a stump.

Loading...

The crack grows into a cave from hydraulic action and abrasion.

Loading...

The cave breaks through the headland forming a natural arch.

Loading...

This leaves a tall rock stack.

Deserts

1. Try out the desert matching game.

2. Find different images for the terms

Desert Matching Game

Abraded Rock

Desert Pavement

Dunes

Loess

3. Match the definitions to their terms using the pen tool

The grinding and wearing down of rock surfaces by other rock or by sand particles.

Desert Pavement

The removal of fine sediment by wind

Deflation

Made up mostly of pebbles and small broken rock, it is the surface left behind when sand is blown away.

Dunes

Mounds of wind-deposited sand.

Abrasion

Thick deposits of windblown, fine-grained sediment

Loess

4. Check out the animation of a sand dune being formed. Answer the question in the yellow box.

Sand Dune Formation

What do you notice about the top of the dune and the wind direction?
The wind pushed the top of the sand dune in the direction it is blowing.

Glaciers

1. Check out the apline glacier and continental glacier puzzles.

Alpine Glacier

Continental Glacier

2. Add 3 images or 3D models showing glaciers

3. Use the diagram to answer the questions in the yellow box.

Which landforms in this picture of an alpine glacier are familiar to you?
U-shaped valleys, Hanging valleys

Which landforms are new?
Aretes, Cirques

Tell me how you will remember one of these new landforms.
Cirques = circle = bowl shape

Mixed...

Use the white box to share a picture of the word. Also, add a text box describing the word.

glacial grooves

Grooves cut into bedrock by gravel and rocks carried by glaciers.

fjord

A long, narrow, deep body of water. They reach far inland

sink hole

Common where limestone, carbonate rock, salt beds, etc is below the surface. The rock is dissolved by groundwater circulating through them.
