What is the difference between drought, flood, flood and drought?

Drought and flood refers to the flood caused by surface runoff after drought and rainstorm, which makes the surface unable to absorb water immediately and allows water to penetrate into the ground immediately.

Flood is caused by surface runoff because groundwater is saturated and water can't penetrate underground.

Flood and drought disaster means that the weather turns hot immediately after heavy rain, and the evaporation is far greater than the infiltration of water, which is a drought caused by crops not absorbing enough water.
