Question

erosion vs weathering card sort
erosion carries away rocks and soil
weathering breaks down rocks and soil
grid of 12 images on left, empty grids under erosion and weathering on right

Explanation:

To solve this card - sort problem about erosion and weathering, we first need to recall the definitions:

• Erosion: The process that carries away rocks and soil (involves movement, like by wind, water, etc.).
• Weathering: The process that breaks down rocks and soil (no movement, just breakdown, like by ice, chemicals, or temperature changes).

Step 1: Analyze each image for Erosion (carries away)

• Images showing movement of materials:
• The image with a river carrying sediment (maybe the one with a stream or water - related landscape) – water erosion carries away soil/rocks.
• The image with wind - shaped rocks (like desert landscapes with wind - formed features) – wind erosion carries away particles.
• The image with a beach or sediment being moved by water (like the coastal image) – water erosion.
• The image with a muddy area where water is transporting soil (like the one with a stream of mud) – water erosion.
• The image with a landscape where materials are being transported (e.g., the one with a gully or eroded landform due to water flow) – water erosion.
• These images should go into the "Erosion" column as they show the carrying - away of rocks/soil.

Step 2: Analyze each image for Weathering (breaks down)

• Images showing breakdown without movement:
• The image of a cave (formed by chemical weathering of rocks, like limestone by water) – breakdown of rock.
• The image of cracked rocks (maybe due to temperature changes or ice wedging) – physical weathering, breakdown of rock.
• The image of a rock formation with cracks (like the one with a rock split) – physical weathering, breakdown.
• The image of a dry, cracked earth (maybe due to physical weathering from drying and wetting cycles) – breakdown of soil/rock.
• These images should go into the "Weathering" column as they show the breakdown of rocks/soil without movement.

For example, if we take the image of the cave (formed by chemical weathering), it belongs to Weathering. If we take the image of a river carrying sediment, it belongs to Erosion.

Let's assume we are sorting the first row images:

• First image (desert rock formation, maybe wind - eroded): Erosion (carries away by wind)
• Second image (mountainous area, maybe with water erosion carrying away): Erosion
• Third image (rock with ice, maybe ice wedging - weathering): Weathering

And so on for all the images, using the definitions of erosion (carries away) and weathering (breaks down) to sort them into the respective columns.

If we were to give a general answer for the sorting principle:

Erosion is the process of carrying away rocks and soil (involves movement of materials by agents like wind, water, etc.). Weathering is the process of breaking down rocks and soil (no movement, just breakdown by agents like ice, chemicals, temperature changes). So, sort images showing movement of rocks/soil into "Erosion" and images showing breakdown (no movement) into "Weathering".

Answer:

Sort images based on the definitions: Erosion (carries away rocks/soil) and Weathering (breaks down rocks/soil). Images with material movement (e.g., water - carried sediment, wind - shaped rocks) go to Erosion. Images with rock/soil breakdown (e.g., cracked rocks, cave formation) go to Weathering.
