Key Stage 2
Meaning
Environmental change means a change in the conditions of a habitat.
About Environmental Change
- The environment depends on the temperature, amount of water, amount of sunlight and the amount of nutrients in the soil.
- When there is an environmental change this can change or destroy a habitat.
- Environmental change can cause certain types of creature to die.
- Too much rain can cause floods which kill creatures that live underground.
- If there is not enough rain it causes a drought and creatures run out of water.
- If a habitat gets too cold lots of the creatures might die.
Examples
 |
 |
| If the temperature of Arctic habitats goes too high all the ice will melt and polar bears might all die. | Woodland habitats are cut down to make room for fields for cattle. When the woodlands are taken away the creatures that need that habitat will die. |
 |
 |
| Pollution like litter can kill lots of creatures in a habitat because they eat it by accident and it gets stuck in their stomachs. | An asteroid hit the Earth 66 million years ago and the dust and ash from the fires blocked out the sunlight for years. This caused all the dinosaurs to die. |
 |
 |
| Making 'nature reserves' that humans are not allowed to damage can make sure habitats are not destroyed. | Building a pond in a garden provides a habitat for many wild animals and plants. |
