Answer:
Mars is similar to Earth in many ways, having many of the same "systems" that characterize our home world. Like Earth, Mars has an atmosphere, a hydrosphere, a cryosphere and a lithosphere. In other words, Mars has systems of air, water, ice, and geology that all interact to produce the Martian environment.
Explanation:
If the sin 30° = 0.5, then the cos 60° = 0.5
Answer: The potential energy in the system is greatest at X
Explanation: Potential energy is how much energy an object can have. Gravity has an effect on potential energy, the higher something is, the more potential energy it has. For example, if you hold a book above your head, that book has potential energy. When you drop the book, it has kinetic energy. Therefore, since point X is the highest point, the ball has the greatest potential energy there.
Ocean currents act much like a conveyor belts, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
