Term
| Name 3 ways in which Desert Animals are adapted to save water and keep cool. |
|
Definition
1. Large surface area compared to volume.
2. Efficient with water (Lose less water by producing small amounts of concentrated urine and making little sweat).
3. Good in hot conditions (Have thin layers of body fat and a thin coat to help them lose heat. eg. camels keep nearly all their fat in their humps). |

Name 3 ways in which Arctic Animals are adapted to save water and keep cool. |
|
Definition
1. Small surface area compared to volume.
2. Well insulated (Have a thick layer of blubber for insulation which also acts as an energy supply when food is scarce). |

Term
Name 3 ways in which Desert Plants are adapted to having little water. |
|
Definition
1. Small surface area compared to volume (Plants lose water from the surface of their leaves so cacti have spines instead of leaves to reduce surface area).
2. Water storage tissues (Cacti store water in their thick stems).
3. Maximising water absorption (Extensive or deep roots). |

Term
| How can Air pollution be monitored by a living indicator? |
|
Definition
| Lichen are used. They are very sensitive to the amount of sulfur dioxide in the atmosphere. More Lichen = Cleaner Air. |

Term
| Name three non-living indicators of Environmental Change. |
|
Definition
1. Satellites (Measure the temperature of the sea surface and the amount of snow and ice cover).
2. Automatic weather stations (Measure atmospheric temperature).
3. Rain Gauges (Measure rainfall). |
