The video tutorial explains droughts, which are prolonged periods without rain, affecting nature and humans. It covers three types of droughts: meteorological, hydrological, and agricultural. Meteorological droughts occur with less rainfall than usual, hydrological droughts happen when groundwater levels drop, and agricultural droughts affect crop survival due to insufficient rainfall.

• A short period of heavy rainfall

Which of the following is a consequence of droughts?

• Expansion of forests

• Rise in groundwater levels

• Increased food production

• Death of plants and animals

What defines a meteorological drought?

• Low groundwater levels

• Less rainfall than normal in an area

• Excessive rainfall in a short period

• High humidity levels

What happens during a hydrological drought?

• Groundwater levels rise

• Rainfall exceeds normal levels
