A skydiver jumps out of an airplane and begins to accelerate to terminal velocity. When he reaches 3000 feet, he opens his parachute and slows to 20 m/s. What happens to the skydiver's motion when he opens the parachute?
He accelerates (jumps backward) because air resistance is greater than the force of gravity
400
What is the difference between speed and velocity?
Velocity is speed with a specific direction
400
This is the process of rocks being broken down into smaller sediments
What is weathering
500
This is the geologic feature that marks separation lines of tectonic plates

A boy is trying to pull a dog on a leash, the dog and the boy are moving in the same direction. Describe the forces (balanced or unbalanced) and identify if there is a greater force.
These are unbalanced forces. The dog's force is greater because they are both moving in the direction the dog is pulling.
