Increase of green house gases, due to human activity, is warming the oceans. this causes changes in climate. name three earth spheres which interact in this process. justify your answer.

Atmosphere: Gases like methane and CO2 trap heat, preventing radiation from the sun's energy from bouncing back out into space. This heats up the atmosphere

Crysphere: As the oceans and the rest of the planet heats up, so does the area of the planet that is always or usually frozen. As the cryosphere melts and shrinks, The area of the planet that is white shrinks as well, which leads to more of the planet absorbing the sun's heat. 

Hydrosphere: Naturally, the oceans compose the majority of the hydrosphere, so the oceans heating up affects the hydrosphere. Additionally, the oceans heating up and the rising water levels that come with that process can expand the hydrosphere further inland and also affect other bodies of water, such as lakes and rivers. 

Letter a, because when there are unlike charges they will always attract to each other.
