A small rock lies on a slope near a tropical sea. What are three ways that the rock could be eroded?

1. During a rockfall, the rock could be carried down the slope.
2. Frost wedging could cause cracks in the rocks.
3. The heat of the sun could break down the rock.
4. Tall, powerful waves could carry the rock into the ocean.
5. The rock could react to seawater, break down, and be carried away by the sea.

 For Plato students the correct answer is

#2. Frost wedging could cause cracks in the rocks.

#4. Tall, powerful waves could carry the rock into the ocean.

#5. The rock could react to seawater, break down, and be carried away by the sea.

Explanation:  There were so many different answers given by everyone but this is the correct answer if you are on Plato

volts times amps 6 x 0.5 3w

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
