geography-development,climate change.

Weather

Day to day changes in the atmosphere

Biome

A large scale ecosystem that occupies a region of the earth based on its climate zone

Climate

The average precipitation amd temperature of an area measured over 30 year periods

a reason why climate change is controversial

Because there is evidence that climate change is a natural process that has been proved to happen from before humans were born. But others believe humans are a huge part of climate change and some even think they are the reason.

Name historical evidence of climate change

Ice cores, fossils, paintings, pollen, tree rings.

Name current pieces of climate change evidence

Sea ice decreasing and sea levels rising, co2 increase

Natural causes of climate change (orbital theory)

Over time earths orbit changes from circular to elliptical. It also tilts on its axis and wobbles. This changes how much sunlight we get.

Natural greenhouse gas effect-

Natural ways greenhouse gasses get released into the atmosphere. More heat escapes into space.

Human causes of climate change

Deforestation, fossil fuels

Describe how humans release gas into the atmosphere

Humans release gasses in agriculture a lot from cows. Cows and rice farming release methane-a greenhouse gas. Which heats our earth. This happens by solar radiation then less heat gets released into space.

Human enhanced greenhouse effect-

Ways humans release greenhouse gasses into the atmosphere warming our earth. Less heat escapes into space.

Desertification

The process of fertile land degrading and becoming more desert like, this happens because of drought, deforestation and over farming.

Sea levels rising

The process of the water levels in our oceans increasing. Because the ice on the land melts and or water that has been heated up expands. (Chemical expansion)

Development-

Means people reaching an acceptable standard of living or quality of life

Quality of life-

The general well-being of people which includes income, health, education, employment and their environment

Quality of life effects-

Economics-money, pension

Social-medical care, hygiene

Environmental-clean water, forests

Political-freedom of speech, fair legal systems

Levels of development-

Developing, emerging, developed.
