Biomes (GCSE Geography)

True or false.

A biome is a global scale ecosystem with a collection of plants and animals that have common characteristics for the environment they exist in.

• True

• False

Which biome is found in the Arctic Circle, where the sun's rays have little strength. temperatures are below freezing most of the year.

• Deciduous trees

• Coniferous trees

• Tundra

• Temperate grassland

Which biome is found close to the Tropic of Cancer and Capricorn. The air that rises over the Equator heads polewards after shedding its moisture as rain. The Sun's rays are still highly concentrates at this low latitude.

• Temperate forest

• Temperate grassland

• Hot deserts

• Cold deserts

Why is altitude important?

• Temperature falls by 1/2 a degree for every 100m increase in altitude, and tough grasses replace trees on steep mountainside.

• Temperature increases by 1/2 a degree for every 100m increase in altitude, and tough grasses replace trees on steep mountainside.

• Temperature falls by 2 degrees for every 100m increase in altitude, and tough grasses replace trees on steep mountainside.

• Temperature increases by 2 degrees for every 100m increase in altitude, and tough grasses replace trees on steep mountainside.

Why is relief important?

• Mountain ranges in inland areas isolated from the sea suffer from low rainfall. This is because winds blowing off oceans quickly lose their moisture when air is forced to rise upwards over high mountain range.

• Mountain ranges in inland areas isolated from the sea suffer from high rainfall. This is because winds blowing off oceans quickly increase in moisture when air is forced to rise upwards over high mountain range.

• Low land plains in inland areas isolated from the sea suffer from low rainfall. This is because winds blowing off oceans quickly lose their moisture when air is forced to rise upwards over high over the plains.

Ocean currents are important to biomes. Which of the following statements is true?

• The cold gulf stream affects the climate in Western Europe

• The cold gulf stream affects the climate in Easter Europe

• The warm gulf stream affects the climate in Western Europe

• The warm gulf stream affects the climate in Eastern Europe

Where are deciduous forests found?

• South East China

• Western Australia

• Northern Russia

• Western Europe

At which of the following locations would you NOT find deciduous forests?

• Eastern USA

• South Argentina

• SE Australia

• South Mexico

The Mediterranean biome consists of drought resistant small trees and evergreen shrubs that grow how many degrees north of the equator?

• Three degrees

• Between 40-60 degrees

• Six degrees

• Between 60-70 degrees

Coniferous forests are found where winter temperatures are extremely cold due to a lack of insolation. Due to the Earth's tilt, there is no sunlight for some moths of the year.

At what degrees north are coniferous forests found?

• 30 degrees north

• 40 degrees north

• 50 degrees north

• 60 degrees north
