4. The water cycle is balanced because

Sergeu [11.5K]

Answer:

hello!

Explanation:

The water cycle is critical not only to weather, but to life on earth. Rain is necessary for the survival of plants and humans.

Condensation is necessary for cloud formation. Evaporation is necessary to cooling and keeping a good balance of water vapor in the air.

The water on Earth now is the same water that’s been on Earth since the beginning.

What makes that feat possible? The water cycle. The water cycle is the process that re-circulates water so we can have bodies of water as well as clouds and precipitation.

The first step of the water cycle is evaporation. About 85% of the water vapor in the air comes from water that evaporated from the oceans. The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land.

This includes water vapor produced by plants during transpiration, water from lakes, streams, puddles and soil moisture, direct evaporation of snow and even water vapor from the breath of animals.

The second step of the water cycle is condensation. Now that the atmosphere is full of water vapor, that water vapor condenses into water droplets. Sometimes, like early in the morning, the water vapor condenses on the grass as dew and seeps back into the soil, ready to be evaporated again.

But most of the water vapor condenses higher up in the air and forms clouds. Once the water droplets are in a cloud, two things can happen. Either the cloud will dissipate and the water droplets will become vapor again, or the cloud will grow and it will begin to precipitate.

The third and final step of the water cycle is precipitation. Precipitation includes all water that falls from the sky, both in liquid and frozen form, which reaches the ground.

Once the precipitation makes its way to the ground it can end up soaking into the ground, run off into streams and lakes, become snow cover, be used by plants, be inhaled by animals or fall directly back into the ocean. Then the water cycle can begin again and continue for millions of years to come.

tekilochka [14]

Answer:

The correct answer is - Fossil fuels are cheaper than alternative forms of energy.

Explanation:

Fossil fuels are made by the natural process in a longer time period such as anaerobic decomposition of the dead organism like plants, and animals. These plants and animal's decomposed organic matter pilled up to form coal, or natural gases or crude oil.

By the use of such fuels the reserves are continuously depleting and will be no longer available in the future if not managed properly as it can not be renewed. Fossil fuels increases the green house gases in environment and affect it by incresing carbon in atmosphere. However, these fuels are cheaper in comparision of other fuels.

Thus, the correct answer is - Fossil fuels are cheaper than alternative forms of energy.

1. Describe the unspoken culture in Mississippi. How does this compare to any unspoken culture that you’re aware of where you live? Explain.

The death penalty is part of the unspoken culture. If you murder someone you are going to receive the death penalty. Idaho has only executed 23 people since 1977. So not as much as Mississippi.

5. What are your thoughts on the death penalty? Do you believe that people are less likely to commit murder or violent crimes in states that have the death penalty? Evaluate and explain. I believe in the death penalty based on the crime committed. And yes I think less people would commit crimes if we actually went through with the death penalty.
