Question

answer the three questions on this slide. please fill in the top and answer the question your martian is asking in complete sentences. what is moving (erosion) the rock in this canyon? ______ wow, this canyon is deep! can you explain to me what happened? do you think fast water or slow water is breaking this rock (weathering) and carving this canyon, and explain your answer?

Explanation:

1. Answering "What is moving (erosion) the rock in this canyon?"

Erosion in a canyon context often involves water (like a river) moving the rock. So the answer is: "Water (such as a river flowing through the canyon) is eroding and moving the rock in this canyon."

Over time, weathering (breaking of rock) and erosion (movement of rock material) by water (likely a river) worked together. The water first weathered the rock (broke it into smaller pieces) and then eroded (carried away) the rock material, gradually carving out the deep canyon we see.

Fast - moving water has more energy. This higher energy allows it to exert more force on the rock, which is better for both weathering (breaking the rock) and erosion (carrying the broken rock away). Slow - moving water has less energy and would be less effective at breaking the rock and transporting the material to carve a deep canyon. So fast water is more likely responsible.

Answer:

Water (such as a river flowing through the canyon) is eroding and moving the rock in this canyon.

2. Answering "Can you explain to me what happened?"
