Answer:
moving
Explanation:
They've been moving for thousands and thousands of years. Millions of years ago there was a land called Pangea that seperated into the continents we see today.
Answer:
Speed and velocity both measure an object’s rate of motion. However, speed is a scalar quantity, which means that it can be described with a numerical value. Velocity is a vector quantity, which depends on direction as well as magnitude. Read these definition for more information:
speed - the rate of distance traveled by a moving object over time
velocity - the rate of displacement of a moving object over time
Basically, an object’s speed tells you how fast it’s going. Its velocity tells you how fast it’s going in a certain direction. You use speed measurements in your daily life, but physicists depend on velocity measurements more frequently in their work.
