Q: As the distance between the objects increases, the force of gravitational attraction decreases.  Would an astronaut floating five million miles away from the Earth experience less gravitational attraction to the Earth than an astronaut on the surface of the Earth or more gravitational attraction to the Earth than an astronaut on the surface of the Earth?
A: less gravitational attraction to the Earth than an astronaut on the surface of the Earth


Q: The glaciers on Earth are getting smaller and smaller as Earths temperature rises.  Rick is able to prove that in fifty years, the Earth's average temperature will be significantly higher. Based off of this information, he could also deduce then that the number of glacier's on earth in 50 years will be higher or lower?
A: lower
