How does an artificial satellite gather information about objects in space?
A.
It flies into the atmospheres of objects and uses infrared sensors to measure temperature.
B.
It stays on the surface of the Earth and gathers radio waves from distance objects.
C.
It orbits objects or points toward them and uses cameras and sensors to obtain data.
D.
It rotates around the surface of the moon and uses magnets to measure distant objects.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
