Answer:
The third one is the right one it was on my AP PRE EXAM
Explanation:
Convection currents occur in the MANTLE. The mantle is the second layer of the earth after the crust. The mantle is approximately 2900 km thick. Convection currents are triggered or fueled by the heat from the Earth's core.
The part of the mantle closest to the core gets heated. It then becomes less dense than the layers above so it rises. When this rising plume interacts with the crust it cools and becomes more dense than the layers below and so it sinks and this circular motion continues to form convection currents.
The more northern the more colder the more towards the middle of the earth you are the warmer it is. Either it's ice or water.
My preferred way to divide complex numbers is to multiply numerator and denominator by the complex conjugate of the denominator
Answer:
Climate change is a very bad problem caused by us humans. Our carbon footprint has caused polar ice caps to melt, sea level to rise, and weather to get hotter. Climate change is mostly caused by big factories that emit chemical smoke into the atmosphere. This change change is also caused by the carbon dioxide that is produced by cars. One way people could reduce climate change is by using electric cars or by taking the bus more often.
