PPT-Glaciers, Climates and Global Warming

Glaciers Large masses of ice that form on land for a number of years more snow falls in winter than melts in summer deform and flow due to their own weight force of gravity strength of ice Parts in the Mountains. Many people consider that Global Warming is the greatest environmental threat of the 21. st. Century. . However, during the 80s and early 90s scientists argued about the causes and effects of global warming. . Click on the image at right to view the video.

Glacier. : A large mass of ice resting on land or floating as an ice shelf in the sea adjacent to land. By Amanda Vang and Sydney Billington. What is Global. Warming?. Global warming is a when the earth’s temperature increases and it can change the earth’s climate permanently. Released greenhouse gases, increased amount of carbon dioxide, burning fossil fuels and human activities such as driving and cutting down trees and plants can cause global . Foreman Room 102. 1. Global Warming and Ozone Depletion take place in two different layers of the atmosphere: . Global Warming. Ozone . Depletion. Global Warming vs. Ozone Depletion: Causes. Global Warming: cars, factories, rice farming, landfills: . Tropical climates are somewhat variable . In terms of moisture. In terms of temp on a day-night cycle. And somewhat consistent. In terms of annual temp. In terms of incoming solar radiation. Diurnal compared to annual temperature ranges defines the tropics. Liceo. . Scientifico. “G. . Galilei. ”. Pescara. S. 2012 – 2013.
