Chapter 35 GeoTerms: Antarctica and Climate Change
Terms in this set (32)
a very large ecosystem with its own community of plants and animals such as a desert, forest, wetland, or grassland
a large, floating sheet of ice over the sea, often extending hundreds of miles
large mass of ice found near Earth's poles (continental) or in a high, cold mountain valley (alpine)
energy from the sun that can be converted into heat or electricity
the huge social and economic change in Europe and the United States that was produced by the shift from hand tools to machines in the 18th and 19th centuries.
moisture that falls from the sky as rain, snow, sleet, or hail
Gases in Earth's atmosphere that trap heat near the surface
A long cylinder of ice obtained from drilling through ice caps or ice sheets; used to study past climates.
the gradual increase in the temperature of Earth's surface over time. This warming may be the result of natural causes. It may also be caused by human activity
a community of all the living things in an area and the environment in which they live
the pattern of weather over a long period of time
any fuel, such as petroleum, coal, and
natural gas, that is made from the remains of prehistoric plants and animals
a climate/climate zone that is cold all
year with permanent ice and snow; permanent, dome-shaped covering of ice over a large area that is too cold to support plant life
Greenhouse gas effect
global warming caused by more heat being trapped near the Earth
A thin layer of gases surrounding Earth
a fast-moving section of an ice cap
A desert at the poles with ice but little precipitation
Large mass of floating ice
the official count of a population
What started Global Warming?
The Industrial Revolution
Global Warming Theory
1. Earth's climate is getting warmer 2. Trend caused by humans 3. Global warming is harmful to people and biomes
Global Warming Opposition
Some places are getting warmer, others are getting colder. It is not consistent and could be caused by nature.
Big producers of CO2
Rich and industrialized countries
Small producers of CO2
Less developed countries or more environmentally aware.
Examples of big CO2 producers
Australia, Canada, China, Kuwait, Saudi Arabia, United States
Examples of small CO2 producers
Argentina, Egypt, Nigeria, South Africa
Impact of Rise in Sea Level
Flooding of Tuvalu, Bangladesh, and parts of coastal United States
First Step to Greenhouse Effect
Sun's energy enters the atmosphere
Second Step to Greenhouse Effect
burning fossil fuels increase levels of greenhouse gases
Third Step to Greenhouse Effect
greenhouse gases absorb some of the heat energy and trap it
Fourth Step to Greenhouse Effect
the Earth's surface absorbs the energy and is warmed by it
Which part of Earth is growing warmer, according to the Global Warming Theory?
