Question

Briefly, what is the mid-ocean ridge? The South Atlantic Ocean is formed as Africa and South America split apart. What kind of plate boundary isthis? Think of the Earth's oceans as a giant bathtub. A volcanic mountain chain erupts in the middle. What is going to happen to the water level in the bath--will it RISE or FALL? Throughout Earth's history, there have been times with increased periods of tectonic activity, with the number of mid-ocean ridges increasing as well. What do you think happened to the global sea level at these times--will it INCREASE or DECREASE? How do you predict having a continent move towards the north OR south pole will affect sea level on Earth-will it INCREASE or DECREASE? (Remember, this will cause glaciers to form on LAND) What will the sea level do if that continent then moves away from the poles-will it INCREASE or DECREASE? Mountain-building on land increases exposed surface area of the Earth, which increases erosion, which reduces the amount of carbon dioxide (a greenhouse gas) in the air. What effect does mountain building have on the climate-will it INCREASE or DECREASE global temperatures? What effect will this have on global sea level-INCREASE or.
