3.3 List 2 naturally occurring greenhouse gases. 3.3 How does the sun’s energy affect climate. More energy, hotter, temp increase. More energy, cooler, temp decrease Less energy, hotter, temp increase Less energy, cooler, temp decrease 3.3 How does the earth’s curved surface affect climate. 3.3 How does earth’s tilt affect climate – tilted away from sun. Warmer Cooler Stays the same Why? 3.3 How does earth’s tilt affect climate – tilted towards the sun. Warmer Cooler Stays the same Why? 3.3 How does earth’s orbit affect climate – more circular. Why? 3.3 How does earth’s orbit affect climate – more elliptical. Why? 3.3 What would happen if the earth was no longer tilted.
A – more energy, hotter, temperature increase Water vapour Carbon dioxide Methane Nitrous oxide B – cooler (further and less direct) Direct sunlight at equator, therefore hotter. Less direct as we move away from the equator, therefore cooler More constant energy, A – warmer (closer and more direct) No seasons, temperature would depend on latitude. Amount of energy changes from point on orbit to further point
