Introduction to Weather and Climate

1. The sun radiates eat the warms the earth.
2. They receive more direct sunlight throughout a calendar year which keeps it warmer than polar regions.
3. Albedo is the fraction of radiation that reflects back into space. The black roof would absorb more radiation since it has a lower level of albedo.
4. Lapse rate is the rate of atmospheric temperature decrease when altitude increases.
5. Aspect is the compass direction facing a slope. The direction a slope faces can affect biotic and physical features. Plants would grow better on the south side facing side of a mountain in the northern hemisphere.
6. Since the Earth is tilted on its axis going around the sun, certain hemispheres get more sun at one time of the year than others.
7. Land heats up faster because the heat gets absorbed in the surface unlike water which has different physical properties and has to heat all the way through which takes longer.
8. The climate is a lot drier and certain plants can't grow their because of the lack of water, but helps plants like wheat grow really well since they don't need a lot of water.
9. It keeps Norway's coastal water from freezing over with its strong winds even though Norway is close to the arctic.
10. The Alaska current runs past BC.
11. Adding carbon dioxide impacts the atmosphere by heating up the temperature which helps advance global warming.
12. Convection is the collective, concerted movement of a group of molecules within fluids and rheids, usually through diffusion or advection or even a combination of both.
13. Wind is the natural movement of the air, mostly in the form of a current of air blowing in one direction.
14. An urban heat island is an area that is significantly warmer than its surrounding rural areas and it is caused by human activities and can mainly be noticed when the winds are weak in the area. It is mainly caused when the modification of land surfaces use materials that impact the storing of sort-wave radiation.
