Answer:

C. accelerates.

D. changes speed but not direction.

Explanation:

• When the body accelerates, the net force increases, when changes speed, acceleration changes and force as well.

{ \rm{force = mass \times acceleration}}

» So, the force is determined by acceleration.

{ \rm{force = mass \times ( \frac{ \delta \: speed}{time}) }} \\

» Also force is determined by change in speed

Which of the following is a major way in which oceans contribute to weather systems?

provide a diverse habitat for many organisms

experience changes in amounts of dissolved salts

store and transport the Sun's heat energy

reach depths that can be as much as 12000 meters

Answer: Store and transport the Sun's heat energy.

Explanation:

Oceanic currents are just like a conveyor belt. It helps in transportation of the warm water and the precipitation from the equator to the poles and the cold water in the poles towards the tropics. This way the oceans counteract the uneven distribution of the radiation of sun that reaches upto the surface earth. This will regulate the global climate.
