earth cycles and human impacts
Texte du Storyboard
- all of the spheres of our earth, namely the geosphere, atmosphere, biosphere, hydrosphere, interact in diffrent ways such as the hydrosphere providing water for plant growth on the geosphere. the spheres all interact with each other, so lets see what these spheres are and how they connect to each other
- water and air penetrate soil
- the nutrient cycle is a great example of the diffrent spheres interacting with each other, as shown above most of them connect to each other in diffrent ways, such as the ground connecting to the roots
- plant/animal matter breaks down into soil
- decomposers break down organic matter
- rocky subsoil breaks down providing nutrients to soil
- nutrients used to grow
- soil stores nutrients which plants absorb
- as shown above, if one part of the cycle of the spheres doesn't go right, it can negatively affect all of the other spheres which can then affect the sphere that also caused the issue. so if one of the spheres doesn't do its job, it can negatively affect all of the other cycles
- plant and animal waste can't break down into the soil because there is no waster
- x
- what would happen if some of the nutrients are not present
- decomposers have nothing to break down
- no nutreints to use for growth
- soil has nothing to store
