Because drought is defined as a deficit in water supply, it can be caused by a number of factors. The most important one though relates to the amount of water vapor in the atmosphere as this is what creates precipitation. More rain, sleet, hail, and snow can occur where there are moist, low-pressure air systems.
Really hot temperatures can make a drought worse by evaporating moisture from the soil. But droughts don’t just happen in hot and dry places. A close-up image of dry, cracked soil during a drought.

What is drought, its types, causes and effects?
What is Drought, its types, causes and effects. TYPES OF DROUGHT. Agricultural drought : this is type of drought in which the moisture level in the atmosphere minimizes which in turn affects the soil moisture. CAUSES OF DROUGHT. Low rainfall : the main reason for drought is low or lack of rainfall.
Who lives in the community, because some people are more affected by drought than others based on things like health conditions and age. What kind of water system the community has. What rules the community has about water use. Other economic and social factors.
What are the social impacts of drought?
Social impacts of drought are ways that drought affects people’s health and safety . Social impacts include public safety, health, conflicts between people when there isn’t enough water to go around, and changes in lifestyle. Examples of social impacts include:.
How does drought affect the economy?
A drought/food shortage will affect the nations economy as a whole by drastically increasing the price and value of food and transportation of that food. This increase will not allow most average citizens to purchase food for them and their families.
Does drought cause earthquakes?
The gravity recovery and Climate experiment (GRACE measurements) reveals that major earthquakes (Mw 5 and above) always occur in the dry stage, indicating drought and associated groundwater extraction is an important trigger for major earthquakes .
Is drought bad for the Earth’s crust?
As it turns out, changes in stress loads on Earth’s crust from periods of drought can, in fact, be significant.
Is there such a thing as ‘Earthquake Weather?
They also got people talking about all aspects of earthquakes. There are lots of myths about earthquakes. A common one is that there’s such a thing as “earthquake weather” — certain types of weather conditions that typically precede earthquakes, such as hot and dry, or dry and cloudy.
With the advent of seismology — the study of earthquakes — we now know that most quakes are caused by tectonic processes — forces within the solid Earth that drive changes in the structure of Earth’s crust, primarily the rupture of underground rock masses along faults (linear zones of weakness).
When I was writing we ran into the query “Can tides cause earthquakes?”.
We see also that tides can cause faint Earth tremors known as microseisms. But the real problem is taking our knowledge of microseismicity and scaling it up to apply it to a big quake, or a quake of any size that people could feel, really.”.
What are the natural hazards caused by tectonic plate boundaries?
A great variety of natural hazards occur on Earth, including earthquakes, volcanic eruptions, tsunamis, landslides, floods, fires, tornadoes, hurricanes, and avalanches. The most destructive of these hazards, earthquakes, tsunamis, and volcanic eruptions, are mostly associated with tectonic plate boundaries.
Causes of Tectonic Plate Shifts Phenomena Natural events such as Earthquakes and tsunami disasters can occur in a place near the location of the Earth’s plates. There is a possibility that these events can occur anywhere and anytime in all parts of the Earth.
