Deforestation
cutting down trees in forests
2 of 26
Ecosystems
A unit made up of living things and their non-living environment
3 of 26
Enhanced Greenhouse Effect
means the warming of the earths temperatures, and is caused by the enhanced greenhouse effect
4 of 26
Extinction
a species of plant or animal dying out completely, so none survive
5 of 26
Food Chain
plants provide food for plant eating animals(herbivores). Herbivores provide food for meat eating animals(carnivores). Plants and animals are linked together, and depend on eachother
6 of 26
Megafauna
means 'big animals'. Most weighed over 40 kg and included the woolly mammoth, giant elk, sober toothed cat, ground sloth, giant beaver and glyptodon

Thermal Expansion
rising sea levels occur because of rising temperatures because the sea expands as it warms up
8 of 26
Temperature Maritime
a climate that experiences mild temperatures relative to latitude
9 of 26
Polar Front
the boundary between the cold polar air to the north and warm tropical air from the south
10 of 26
Maritime Climates
found close to the sea. Moist air moving in from the sea cools the summer months and warms the winter months, bringing rain all year round
11 of 26
Continental Climates
occur far from the sea in the middle of the continents. The climate is hotter and drier in summers and winters are colder
12 of 26
Decertification
the gradual change of land into desert
13 of 26
Quaternary Period
the last 2.6 million years of geological time
14 of 26
Natural Causes
Volcanic Activity, Sunspots and solar output
15 of 26
Orbital Changes
The Earth’s orbit changes a small amount once every 100,000 years. These are known as Milankovitch cycles
16 of 26
Solar Output
solar energy being fired out front eh sun towards earth
17 of 26
Volcanic Activity
Volcanic eruptions pump ash dust into the atmosphere causing a cooling effect
18 of 26
Little Ice Age
The Mini Ice Age was a colder period in northern Europe starting in the 15th century and lasting to the mid 19th century.
