The diagram below shows stream gradient. How do you calculate stream gradient?
Stream Gradient
Elevation
Difference
Horizontal Distance
O
A. Horizontal distance divided by elevation difference
B. Elevation difference divided by horizontal distance
Ο Ο Ο
C. Elevation difference times horizontal distance
D. Horizontal distance minus elevation difference

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
