the average weather conditions (such as rainfall and temperature) recorded over a 30-year period

the distribution, storage and movement of water in the environment

The factors affecting biome distribution

Geography

This unit teaches pupils about ecosystems and biomes at different scales. Pupils learn about the factors influencing biome distribution and the physical systems and processes regulating them. Pupils will also learn about the impact of population growth and resource extraction on biomes.

Global biomes

Climate is the average weather conditions over a period of a minimum of {{}} years.

the Equator is closer to the Earth's core than the poles

at the Equator, solar energy hits the Earth directly

the Equator has more oceans, which trap heat more effectively

at the poles, solar energy is dispersed by the curvature of the Earth

the Equator is higher in elevation than the poles, leading to higher temperature

Why is it hotter at the Equator than at the poles?

Which key climatic factors influence the distribution of biomes?

Match these global climate zones to the biomes most likely to be found in them.

Put these biomes in the order they are most likely to be found in the Northern Hemisphere, going from the Arctic Circle to the Equator.

What local factors affect biome distribution?

Global biomes are large-scale ecosystems defined by their main {{}} type. 

On which of these continents are tropical rainforests **not** found?

Which of these terms is used by geographers to refer to the spread of something?

The pattern of biomes is broadly latitudinal, with tropical rainforests near the {{}} and tundra nearer the poles.

Determine the biome from the following description of a biome's climate characteristics: high daytime but low night-time temperatures, plus extremely low rainfall across the year.

Which global biome would be most likely to have the climate characteristics shown in this climate graph?
