hydrosphere, geosphere, and biosphere
Explanation:
Katie's experiment most likely represents the interactions between the hydrosphere, geosphere and biosphere. The hydrosphere is the part of the earth that holds water. Geosphere refers to the solid and rocky part of the earth. Biosphere is the domain of life on the earth.
- The water poured represents oceans in the basins of the world which is a part of the hydrosphere.
- The beach sand is the crust which contains the ocean water which is part of the crust.
- The toothpicks on the sand dunes which are the vegetation represents the biosphere.

Average tempreature during the ice age was around 46 degrees Fahrenheit although the polar regions were far colder, around 25 degrees Fahrenheit which is colder than the global average.
A big environmental issue is the erosion, but it is also an issue that can be solved with good planing and in relatively short period of time.
Explanation:
There are many environmental issues, and one of the is the large scale erosion. The reason why I chose this issue is because it is a big problem that can actually be solved relatively easily. The erosion is a natural process and it has always been present, but the problem is that its rates are much higher nowadays because of the human activity. The humans have destroyed lot of vegetation for one reason or another, which in turn led to the soil to be more exposed to the erosive processes. Without having its natural protection from the plants and their root systems, the soil is very easily moved away from its initial location.
- The simplest and cheapest method to stop or minimize the erosion is by planting vegetation that is suitable for the conditions at a particular area.
- The plants that will grow will quickly tighten up the soil with their root systems, and provide cover with the steams and leaves, thus having result in very short space of time.
- The planting of the vegetation can be implemented by the governments, like making a day for planting vegetation on places like this, where all companies and their employees will be obligated to participate. Also, the children from the schools can be included, which will also result in higher awareness for the environment.
- As the places that have been stripped of vegetation tend to be drier and with poor soil, plants like the wild or semi-wild apricots, pistachios, various succulents, can be used, as they grow quickly, are low maintenance or don't require maintenance at all, and on top of it they provide useful products once grown properly.
- The expected results will be minimizing or stopping the erosion in only few years, stopping the large amounts of sediments moving into the rivers, retaining the landscape, lifting up the environmental awareness, and even having profit and benefits on the long run from the plants.
