Lahars are the result of volcanic ash mixing with large amount of water. They can form in two ways.
In some cases an erupting volcano can melt snow and ice near its summit. The resulting meltwater mixes with the ash and forms a lahar. A lahar can also occur without an eruption if heavy rain falls on ash deposits.
What else can I help you with?
Which is not an example of intrusive activity sills and dikes laccoliths lahars Batholiths?
Lahars are not examples of intrusive activity. Lahars are fast-flowing mixtures of water, rock debris, and volcanic ash that move down the slopes of a volcano during an eruption or due to melting snow and ice. Intrusive activities include the formation of sills, dikes, laccoliths, and batholiths, which involve the movement of magma into Earth's crust.
Are lahars examples of intrusive igneous activity?
No. Lahars are the result of extrusive activity.
Can tall structures prevent volanoes and lahars?
No. Tall structures will not affect volcanoes. Dams can potentially mitigate lahars.
Are lahars hot?
Lahars are typically a mix of water, volcanic ash, and debris that flow down the slopes of a volcano during an eruption. While they can be very destructive due to their speed and volume, lahars are not typically hot like lava flows.
Can mud flows and lahars be prevented?
Mudflows and lahars can be prevented or greatly reduced by planting deep rooted vegetation in places they might occur.
What are mudslides produced by volcanoes called?
Lahars
Is the following is an intrusive igneous body Pyroclast Lava Flow Lahar Batholith?
The given options are not all intrusive igneous bodies. A batholith is an intrusive igneous body formed deep within the Earth's crust, while pyroclastic flows, lava flows, and lahars are volcanic hazards associated with volcanic eruptions.
What is wetter lahars or pyroclastic flows?
Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.
Are lahars dangerous?
Yes they are dangerous as the water can flood buildings
Does a lahar come out of an earthquake?
No. Lahars are mudflows that are produced by volcanoes.
What are mount rainiers eruption hazards?
pyroclastic flows, ash, and lahars
Are lahars and volcanoes alike?
No. A lahar is a mudflow composed of volcanic material.
