Question

Breifly discuss earthquakes and floods with respect to their occurrence and impacts

Answer 1

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.

Answer 2

Answer:

Explanation:

Earthquake can be define as an event of movement of the surface of earth. It is caused due to the sudden release of energy in the earth's lithosphere that results in seismic waves. These earthquake can vary in dynamics of their impacts.

Impacts: Due to the shaking of the ground, the earthquake can destroy the buildings, loosen up the roots of long trees and forests. The earthquakes can be responsible for other catastrophic events such as tsunamis and landslides.

Floods is an overflow of water it is responsible for submergence of land that is dry. It happens when the water level of the water body exceeds it's natural limit due to excess rain or mixing of water from other region.

Impacts: The flood water can result in loss of lives, loss of agricultural production, loss of livestock, the flood water enters the buildings and houses. Some water borne disease can also occur in humans and animals.
