you are a molecule of water. choose a starting point in the water cycle and describe the process you would go through to move through the entire cycle.

Hydrologic cycle or water cycle

Explanation:

Hydrologic cycle or water cycle

Is the system in which I continually move through the Earth-atmosphere. I can go through many processes but the most important are evaporation, transpiration, condensation, precipitation, and runoff.

I´m very important because I cover about 70% of the earth´s surface. I provide life and can control the heat by regulating the temperature of the surrounding. Also can drain harmful substances, I can move important minerals through the spheres.  

My journey begins in the evaporation. In this process when I´m on the surface of the earth like in the oceans, the sea, the lakes or in rivers bodies. I can absorb energy from the sun and change to vapor.  

Once I vaporize into water vapor as I rise up in the atmosphere I go through condensation. At high altitudes since the temperature is low, I start to turn into diminut particles of ice or water droplets. With my other sisters when we came close together we can form fogs and clouds in the sky.

Sometimes I became water vapor from the ice directly without passing through the liquid stage. And this process is known as sublimation. This happens when I´m in the ice sheets of the North Pole or in the south Pole or also in the ice caps on the mountains.

When I am high in the sky in the form of clouds due to temperature or wind changes, also when the air cannot hold me anymore I precipitate. Depending on the temperature I can fell down in the form of rain, snow, drizzle, sleet, and hail.

After I precipitate sometimes I´m absorbed by the soil. I can enter into the process of transpiration. This process is comparable to evaporation is where I change from liquid water into water vapor by the plants. First I´m absorbed by the roots of the plants, then I´m pushed toward the leaves where I´m used in the photosynthesis process.  Sometimes I´m moved out of leaves through stomata (extremely tiny openings on leaves) as water vapor.

As I pour down (in any form), it leads to runoff. This is the process where I run over the surface of the earth. When I´m in the snow form also I can melt into water and lead to runoff. As I run over the ground I can move minerals from the top of the soil.  I can combine to form channels and then rivers and I can end up in lakes, seas, and oceans.

Sometimes I can go by infiltration.  This happens when I move deep into the soil. I seep down to increase the level of the groundwater table.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.
