Unformatted text preview: re heat and light per unit of surface area are delivered there. equator receives more sunlight from the poles cause sun strikes the area directly 7. The factor responsible for Earth’s seasonal variations is the Earth’s tilt 23.5° . earth's 23.5 degree tilt is why we have seasonal variations 8. Global air circulation determines climate patterns because descending dry air absorbs moisture at 30 degrees and ascending moist air releases moisture at 0-60 degrees. 9. Deserts are generally found at latitudes 30 degrees north and south of the equator because high temperatures in the tropics evaporate water from the Earth’s surface and cause warm, wet air masses to rise and flow toward the poles. The rising air masses release much of their water content, creating abundant precipitation in tropical regions. The high-altitude air masses, now dry, descend toward Earth, absorbing moisture from the land and creating an arid climate. 10. The affect of large bodies of water on climate is that they moderate the effects of the atmosphere. 11. Mountains affect climate by the amount of sunlight reaching an area, local temperature, and rainfall. 12. A thousand meter increase in elevation would drop the temperature approx. 6°C. 13. A thousand meter increase is equivalent to an 880-km increase in latitude because the temperature drop is the same in both situations. 14. Temperature of water is the driving force in seasonal turnover of lakes. 15. The effect of global warming will have on the American Beach Tree is that it will have more territory further North along the East Coast where it can survive. global warming has an affect on where certain plants can survive 16. L akes - oligotrophic; nutrient poor—eutrophic; nutrient rich W etlands - most productive biome on Earth; able to filter dissolved nutrients and chemical pollutants S treams - most prominent characteristic is their current; salt and nutrient content increase from ….
