A drought is an extended period of significantly below average precipitation in a region.
Severe droughts occur commonly in the interior and towards the western coast of continents, particularly Africa and Australia. However, they can occur anywhere, and with different levels of severity.
Drought is an abnormally long period of dry weather because there is a severe lack of water in an environment over an extended period of time. For a drought to happen, it means that rainfall has fallen below the average necessary to water crops and/or livestock, and to refill dams for months at a time. When moisture near the ground rises into the colder areas of the upper atmosphere rain clouds form. High pressure in the atmosphere causes air to rise instead of falling, resulting in dry, sunny weather. When high pressure cannot be displaced by low-pressure for an extended period of time, the result is drought.
Lack of rain may be a result of the El Nino phenomenon, which brings dry conditions to some parts of the world for sometimes as long as several years at a time. This is why the southern continents of Africa and Australia are particularly prone.
Desertification is a vicious cycle which increases drought-like conditions, and makes it increasingly difficult for the land to recover. Desertification may occur as a result of man's intervention in the environment, particularly activities such as deforestation and cutting down trees, over-grazing of stock animals, or farming unsuitable crops for a region (e.g. rice, which has to have large amounts of water pumped to it).
Some recent droughts are believed to have happened because of global warming.

How do droughts happen?
Droughts happen when there is an extended period of below-average precipitation, leading to water shortages in an area. Factors such as climate change, changes in weather patterns, and human activities like deforestation and overuse of water resources can contribute to the occurrence and severity of droughts.
Can droughts occur in any climate?
Yes, droughts can occur in any climate. They are typically caused by a prolonged period of below-average precipitation, which can happen in various climate zones, from arid to humid areas. The severity and duration of droughts vary depending on the region and its unique climatic conditions.
When do most droughts occur?
Droughts can occur at any time of the year, but they are most common in regions that experience a prolonged period of below-average rainfall. The timing of droughts can vary depending on the location and climate conditions of a specific region.
What are long periods of unusually low precipitation called?
Long periods of unusually low precipitation are called droughts. Droughts can have significant impacts on agriculture, water resources, and ecosystems.
Do droughts cause earthquakes?
No. Earthquakes and droughts are completely unrelated phenomena.
When do droughts happen?
droughts happen when there is a spell of very dry weather when there is very little rain
Where are Droughts?
Droughts are not held, they happen. They happen where there is not enough rain or a man made interference in water getting to where it's needed.

Do droughts happen in Antarctica?
Antarctica is a polar desert with an average humidity of five percent. It is the driest continent on earth.
Where in the world do most droughts happen?
droughts usually happen between 15 and 20 degrees latitude because those are the permanently arid and continental regions (very dry). These regions are permanently arid because warm tropical air masses descend to hearth surface and become hotter and drier.
Can drought happen anywhere?
Droughts can happen anywhere in the world, but they are more common in arid and semiarid regions with low rainfall and high temperatures. Climate change is also making droughts more frequent and severe in many areas.
Common locations where droughts happen?
they most likely happen in very hot places where there isn't alot of rain i think
Can droughts occur in any climate?
