Question

Excessive rains may cause…….

Answer 1

Hint: Excessive rains cause a condition in which water overflow on normally dry ground or every possible place and area because of overflowing river or dam break or even due to heavy rainfall in a particular area.

Complete step by step answer:
Excessive rains may cause a flood. It is an overflow of water that submerges the land. Flooding may occur as an overflow of water from water bodies, like a river, lake, or ocean, during which the water overtops or breaks levees, leading to a number of that water escaping its usual boundaries, or It can also occur because of an accumulation of rainwater on saturated ground in an areal flood.
The effects of flooding include loss of life and damage to buildings and other structures, including bridges, sewerage systems, roadways, and canals. Floods also cause damage to power transmission and sometimes power generation, which then has knock-on effects caused by the loss of power. This includes loss of portable water treatment and water system, which can lead to loss of portable water or severe water contamination. it's going to also cause the loss of disposal of sewage facilities. The danger of waterborne diseases increases as freshwater combined with human sewage within the floodwaters, which may include typhoid, giardia, cryptosporidium, cholera, and lots of other diseases depending upon the place or location of the flood. Damage to roads and transport infrastructure may make it difficult to mobilize aid to those affected or to supply emergency health treatment.
So, Excessive rains may cause floods.

Note: Many of us get confused between flood and tsunami. Tsunamis are not associated with weather. Tsunami is caused by earthquakes which are caused due to the shifting of tectonic plates below the water bodies.
