So, first of all let me explain the process of hydration to you.
The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
Considering this information, the answer is D.
Temperature is usually the most important of these weather factors in determining what plant and animal species can exist in an area. Temperature determines what kinds of species can live in an area because the climate determines what types of plants can grow and also what kinds of animals can live in an area. Certain species of animals have particular temperature ranges in which they live and thrive in.
Answer:
Drought is a dangerous condition which decreases the quality of life. It is termed as a natural disaster with harmful effects. A drought usually occurs when a region faces a shortage of water. This is mainly due to lesser rainfalls. In addition, droughts have proven to be fatal for mankind and wildlife as well.
Moreover, drought is the most dangerous for a farmer. As they do not have an ample supply of water, their crops dry out. This becomes a reason for worry as it is their sole income. Furthermore, drought also leads to various other problems for the environment and mankind.
Causes of Drought
Drought is caused due to various reasons. One of the main reasons is deforestation. When there will be no trees, the water on land will evaporate at a faster rate. Similarly, it lessens the soil capacity to hold water resulting in evaporation.
Moreover, lesser trees also mean lesser rainfall which eventually leads to drought.
Furthermore, as the climate is changing, the water bodies are drying up. This results in a lower flow of surface water. Therefore, when the rivers and lakes will dry out, how will the people get water? In addition, global warming is a major cause of this. The greenhouse gas emitted causes the earth’s temperature to rise. Thus, it results in higher evaporation rates.
Subsequently, excessive irrigation is also a great cause of droughts. When we use water irresponsibly, the surface water dries up. As it does not get ample time to replenish, it causes drought.
