Question

Why droughts and floods have both positive and negative impacts? ​

Answer 1

Answer:

causes of drought:- If it does not rain for a long period of time, what will happen? The soil will continuously lose groundwater by the process of evaporation and transpiration. Since this water is not brought back to earth in the form of rains, the soil becomes very dry. The level of water in the ponds and rivers goes down and in some cases water bodies get dried up completely. Groundwater becomes scarce and this leads to droughts. In drought conditions it is very difficult to get food and fodder for the survival. Life gets difficult and many animals perish in such conditions.

effects of drought:- Examples of drought impacts on society include anxiety or depression over economic losses, conflicts when there is insufficient water, lower incomes, fewer recreational activities, higher heat stroke incidents and even loss of human life. Drought conditions can also make wildfire risk significantly higher.

cuses and effects of floods:- The amount of rainfall received by an area varies from one place to another depending on the location of the place. In some places it rains almost throughout the year whereas in other places it might rain for only a few days. India records most of its rainfall in the monsoon season. Rains are a big relief after the hot and sunny days of summers. The growth of crops is also dependent on the arrival of monsoons. However, excess rainfall is disadvantageous in many ways. Heavy rains lead to rise in the water level of rivers, seas and oceans. Water gets accumulated in the coastal areas which results in floods. These floods cause extensive damage to crops, domestic animals, property and human life. During floods, many animals get carried away by the force of water and eventually die.

what are the effects of floods:- Floods have huge social consequences for individuals and communities. As most people are well aware, the immediate effects of flooding include loss of human life, property damage, crop destruction, livestock loss and deterioration of health conditions due to waterborne diseases.
