If a drought has a geographical cause, it is not called a drought but a desert. Natural deserts tend to occur in the rain shadows of mountains, far from oceans, or under Hadley Cells. With the exception of problems caused by volcanoes, the weather phenomena caused by geographical features usually remains constant.
A drought is frequently caused by weather. An El Nino means the Pacific Ocean is warmer off the coast of Peru and the Indian ocean is cooler off the coast of Africa. More water evaporates and turns to rain when the ocean is warmer. A La Nina means the opposite. Less water evaporates and turns to rain when the ocean is cooler. That creates a drought.
In the Western United States, people have sold "water rights," which gives people downstream the rights to unimpeded stream flow. As a result many beaver dams were destroyed. With that destruction, a lot of land dried up. That caused conditions to become dryer. That created a man made drought. In Asia much of the land in the center of the empire of Timerlane suffered from over grazing. That created a drought.
Thus, a drought can be caused due to either weather or human activity.

Does catastrophe have weather or geologic or humans cause?
Catastrophes can be caused by a variety of factors, including weather-related events like hurricanes, tornadoes, and floods, geological events such as earthquakes and volcanic eruptions, as well as human activities like accidents, pollution, and wars. The specific cause of a catastrophe depends on the circumstances surrounding it.
Do hurricanes have a weather geologic or human cause?
Hurricanes have a cause rooted in weather. They can be influenced by geographic formations and there is some evidence that human induced climate change can influence them as well, but not cause them.
How do you categorize a tornado as weather related geologic in nature and or caused by humans?
A tornado is categorized as weather related geologic in nature because it is a natural weather phenomenon caused by atmospheric conditions. Tornadoes are not caused by humans, so they do not fall under the category of being human-induced.
Is drought caused by humans or is it geologic in nature?
Geologic refers to rocks, and it certainly isn't caused by rocks. It isn't directly caused by humans, either, though our effect on greenhouse gasses present in the atmosphere is thought to have contributed to an increased number of droughts in recent years.
What are the main causes for drought?
The main causes of drought are lack of precipitation, high temperatures leading to evaporation, and changes in weather patterns such as El Niño. Human activities like deforestation, over-extraction of water, and climate change can also exacerbate drought conditions.
Does wildfires have weather geologic or human causes?
It's a human and geologic cause.
Does a tornado have a weather or geologic or human cause?
Tornadoes are ultimately caused by weather, as they are violenlt weather events.
Does lightning have weather geologic or human cause?
Lightning is a result of atmospheric conditions, mainly within thunderstorms. It is a natural weather phenomenon caused by the build-up and discharge of electrical energy in the atmosphere. Geologic and human activities do not directly cause lightning.
Does the catastrophe have weather geologic or humans cause?
The term "catastrophe" can refer to events caused by a variety of factors, including weather-related disasters (such as hurricanes, tornadoes, or floods), geologic events (such as earthquakes or volcanic eruptions), and human-caused disasters (such as industrial accidents or wars). The specific cause of a catastrophe can vary depending on the situation.
Does volcanos have weather geologic or humans cause?
Volcanoes are primarily a result of geologic processes, specifically the movement of tectonic plates and the build-up of magma beneath the Earth's surface. Weather can influence volcanic activity, but it does not directly cause volcanoes. Human activities, such as mining or drilling, can also potentially trigger volcanic eruptions in some cases, but natural geologic processes are the main drivers.
Does hurricanes have weather geologic or human causes?
Hurricanes should be an weather related and geologic in nature
Does a hurricane have a geologic human or weather cause?
it has a weather cause. ----- The cause of a hurricane is warm water providing power to rising heated air, which produces a cyclonic set of winds because of the rotation of the earth. I would say geologic is the best description of these three.
Do wildfires have weather geologic or human causes?
Human and weather causes. For example, a person might cause it by unattending a camp fire, or discarding a lit cigarette. Or wildfires can be ignited by more natural causes such as lightning for example.
Do earthquakes have weather geologic or human causes?
Earthquakes result from stress in the earth's crust, so the are of geologic origin.
Do wildfires have geologic or human cause?
Human and weather causes. For example, a person might cause it by unattending a camp fire, or discarding a lit cigarette. Or wildfires can be ignited by more natural causes such as lightning for example.
Do earthquakes have a geologic meteorological or human cause?
Earthquakes have a geological cause.
Does wild fire catastrophe have weather or geologic or humans cause?
Wildfires can be the result weather, human action, or geologic activity. Many fires nowadays are caused by humans being careless with campfires or cigarettes. Some even result from deliberate acts of arson. However, there are also plenty of fires sparked by lighting. This is how most natural fires get started. On rare occasions there is a geologic cause: lava flows from volcanoes can start fires. Note however, that no matter the cause, weather plays a major role in how a fire behaves.
