Explain how weathering erosion and deposition happen in our enviroment
eimsori [14]

Answer: Erosion is the process by which natural forces move weathered rock and soil from one place to another. Gravity, running water, glaciers, waves, and wind all cause erosion. Deposition begins when erosion stops; the moving particles fall out of the water or wind and settle on a new surface.

When you drink sea water, what type of solution do you expose your cells to?
Alex Ar [27]
The answer should be 1, hypertonic. 

Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules. 

Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration. 

So, the answer should be 1, hypertonic. 

In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!
