true
True. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push downward on the Earth to make a pole vault, the Earth exerts an equal force upward on the pole.
True. When a ball is thrown into the air, Earth's gravitational force causes the ball to accelerate downward, creating an unbalanced force.
False. All objects with mass exert gravitational forces on each other, not just the Earth.
True. Running water is a significant agent of erosion that exerts a downward force on slopes through the process of erosion and transportation of sediment. This process contributes to the reshaping of landscapes over time.
Yes, the Earth can push an object forward with a reaction force. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When an object exerts a force on Earth, Earth also exerts an equal force back on the object, causing it to move forward.
The force that you exert on the Earth is equal to the force that the Earth exerts on you; for every action there is an equal and opposite reaction, so says Newton. What is different is the amount of motion that results. You move, and the Earth (apparently) does not. Actually the Earth is moving all the time, in its orbit around the sun and by rotating on its axis, but it does not noticeably move because you jump on the ground. And that is indeed because it is much more massive than you are. False.
False. Every object attracts every other object, through the gravitational force.
False. Action-reaction forces always act on different objects. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
False,since it's an air resistance and it's a contact force.

False. The Moon orbits around Earth due to Earth's gravitational pull, but the Sun also exerts a gravitational force on the Moon. The combined gravitational forces of Earth and the Sun control the Moon's orbit.
