1. A frictionless projectileis fired from the North Pole and is aimed along the Prime Meridian. It takes three hours to reach its destination, halfway to the equator. Where does it land? Give longitude and latitude). If the same projectile is fired from the South Pole under the same circumstances, where does it land?( Give latitude and longitude)
2. How can clouds be responsible for cooling the earth in one instance and warming the earth in another?
3. How does climate effect the oceans? How does the ocean effect the climate? Give at least three examples of each
Explanation / Answer
2.When the sun is very active ,its magnetic field is strong.When the magnetic field is strong ,it emits fewer cosmic rays.Because of the fewer cosmic rays ,fewer clouds are formed.Fewer clouds contribute to warming the earth.
When there are more clouds ,the sunlight is reflected back into space ,so it is responsible for cooling the earth .
3. Climate change effects sea levels,causes ocean acidification and effects sea suface temperatures.
The evaporation of water from the oceans causes rain on land,the oceans absorb sun light and also distribute it through out the globe,some times oceans contribute to storms on the earth.
