| Question | Answer |
| what is the atmosphere formed of? | the atmosphere is formed by all the gases that surround the earth. |
| Name all the layers of the atmosphere in order. (5) | 1. troposphere 2. stratosphere 3. mesosphere 4. thermosphere 5. exosphere |
| name characteristics of the Troposphere | The troposphere is the most important layer for living things. |
| name characteristics of the Stratosphere | The Stratosphere protects us from the sunrays, which can cause skin cancer. |
| name characteristics of the Mesosphere | protects the Earth from the meteoroids that managed to break through the thermosphere. |
| name characteristics of the Thermosphere | this layer burns up the meteors that could hurt us badly. There is also a lot of electricity in this this layer. |
| name characteristics of the Exosphere | it absorbs the sun’s radiation, so it shields the layer underneath it. |
| what is the ozone | protects us from the sun. An ozone molecule consists of 3 oxygen atoms chemically bonded together. |
| what is the Hydrosphere | the Hydrosphere is the water space |
| what are the different gases in the atmosphere? | 1. fresh air: a mixture of mainly oxygen and nitrogen 2. other gases: carbon dioxide water vapour argon ozon |
| what are the 3 atoms that make up an ozone molecule? | 1. atomic oxygen 2. diatomic oxygen 3. ozone |
| name the 3 green houses gases | 1. carbon dioxide 2. methane 3. nitrous oxide |
| explain how the green house gas effect. | 1. the sun rays warm the earth 2. a part of the sun's rays are absorbed by the earth 3. a part of the sun's rays are reflected back into space 4. a part of the reflected rays are trapped by green house gases. 5. the trapped rays help warm the earth |
| what is climat change? | a change in global or regional climate patterns. |
| name son consequences of climate change. | 1. melting ice caps: - rising sea level - loss of sea ice 2. longer periods of drought - more wildfires 3. wild life risk - loss of habitat 4. intense heat waves |
| what is the hydrosphere formed of? | the hydrosphere is formed by all bodies of water on the earth. |
| name the different steps of the water cycle in order (4) | 1. evaporation 2. condensation 3. precipitation 4. collection 5. runoff & Infiltration |
