Step-by-step solution for: Weathering, Erosion, And Deposition 5 Worksheet
Here are the explanations for what has occurred in each picture and the factors responsible, based on the definitions of Weathering, Erosion, and Deposition.
Picture 1 (Top Left): Rocky Coastline
* What has occurred: This shows Erosion. The rocks along the shoreline have been worn away and broken down over time. You can see jagged edges and loose stones in the water.
* Factors responsible: The main factor is water (waves from the ocean hitting the rocks) and possibly wind. The constant crashing of waves breaks the rock into smaller pieces and carries them away.
Picture 2 (Top Middle): Cracked Stone Wall
* What has occurred: This shows Weathering. The stone blocks of the wall are cracking and breaking apart while still in their original place. They are not being moved yet, just broken down.
* Factors responsible: This is likely caused by temperature changes (freeze-thaw weathering). Water gets into tiny cracks in the stone, freezes, expands, and pushes the rock apart. It could also be caused by plant roots growing into the cracks or acid rain dissolving the stone.
Picture 3 (Top Right): Dry Cracked Ground with Plant
* What has occurred: This shows Weathering (specifically biological weathering). The ground is dry and cracked, and a small plant is growing through it.
* Factors responsible: The main factor here is plants (biological weathering). As the plant’s roots grow deeper into the soil and rock cracks, they push the material apart, breaking it into smaller pieces. The dryness of the soil also contributes to physical cracking.
Picture 4 (Bottom Left): Natural Rock Arch
* What has occurred: This shows Erosion. A large hole has been worn through the rock formation, creating an arch. The rock material that used to be in the middle of the arch is gone.
* Factors responsible: The primary factors are wind and water. Over thousands of years, wind carrying sand (abrasion) and rainwater have worn away the softer parts of the rock faster than the harder parts, eventually carving out the hole.
Picture 5 (Bottom Middle): Cliff by the Water
* What has occurred: This shows Erosion. The base of the cliff has been cut away by the water, making the cliff face steep and uneven.
* Factors responsible: The main factor is water (wave action). Waves constantly hit the bottom of the cliff, washing away sediment and undercutting the rock above. Gravity may also cause pieces of the cliff to fall after they are weakened by the water.
Picture 6 (Bottom Right): Muddy Dirt Road
* What has occurred: This shows Erosion and Deposition. The dirt road has been worn down by traffic and water, creating ruts. The mud and loose soil have been moved from higher spots and deposited in lower spots or washed off the side.
* Factors responsible: The factors are water (rain turning dirt to mud) and human activity (vehicles driving on the road). The tires of vehicles churn up the soil, and rainwater flows through the ruts, carrying the loose particles away (erosion) and dropping them elsewhere (deposition).
Final Answer:
Picture 1: Erosion caused by ocean waves and wind.
Picture 2: Weathering caused by freeze-thaw cycles or plant roots cracking the stone.
Picture 3: Weathering caused by plant roots growing into the dry, cracked earth.
Picture 4: Erosion caused by wind and water wearing away the rock to form an arch.
Picture 5: Erosion caused by wave action undercutting the cliff base.
Picture 6: Erosion and Deposition caused by rainwater and vehicle traffic moving soil.
