Hey,
option (C) is right ...
Answer:
Gravity
Explanation:
When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.
By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
Answer:
In addition to altering plant communities, the study predicts climate change will change the ecological balance between interdependent and often endangered plant and animal species, reduce biodiversity and adversely affect Earth's water, energy, carbon, and other element cycles.
