- Dynamic Planet
- What is, and Why do we need:
- The Atmosphere
- Layer of gases surrounding the Earth
- Need it for: Oxygen for life, carbon dioxide for plants, greenhouse effect for warmth, and weather and climate.
- The Hydrosphere
- Layer of seas, rivers lakes and groundwater on the crust.
- Need it for: Water for animal and plant life, water cycle.
- The Biosphere
- The thin layer of living things on the crust.
- Need it for: Plant and animals provide us with food, Living things used for medicines and as fuel.
- The Geosphere
- Layer of rocks of Earth's crust and deeper towards the core.
- Need it for: Earths core makes up magnetic field protecting us from space radiation. We use rocks and minerals as resources.
- The Atmosphere
- What is important about the biosphere? How does it interact with other spheres?
- It is important because it is unique: No other planets have one.
- Plants and animals turn rock and sediment (geosphere) into soil.
- Plants are part of the hydrosphere, water cycle.
- Plants take in carbon dioxide and give out oxygen (atmosphere)
- How do the spheres cause harm to us?
- Geosphere: Earthquakes, volcanoes and tsunami.
- Hydrosphere: Flooding.
- Atmosphere: Hurricanes, storms and tornadoes.
- What are humans doing to damage the spheres?
- Polluting the atmosphere
- Destroyed geosphere for fossil fuels
- Deforestation of the biosphere
- Pollution of the water in the hydrosphere
