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 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?
It depends on the kind of catastrophe. Catastrophes such as hurricanes and tornadoes are caused by weather. Earthquakes and volcanic eruptions are geologic events. Train wrecks and industrial accidents are human-caused.
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 earthquakes have a geologic meteorological or human cause?
Earthquakes have a geological cause.
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.
