What causes the formation of Maars?
A maar is formed by one or more underground explosions that occur when hot magma comes into contact with shallow ground water to produce a violent steam explosion. These explosions crush the overlying rocks and launch them into the air along with steam, water, ash and magmatic material.
Can Maars erupt?
Maar is about 300 m in diameter. A maar is a low-relief, broad volcanic crater formed by shallow explosive eruptions. The explosions are usually caused by the heating and boiling of groundwater when magma invades the groundwater table.

What is phreatomagmatic volcanic eruption?
Phreatomagmatic eruptions are a type of explosive eruption that results from magma erupting through water. The second phase of the Eyjafjallajökull eruption in 2010 was phreatomagmatic as a result of magma erupting under ice.
Who made the Maars robot?
Qinetiq
The Modular Advanced Armed Robotic System (MAARS®) is an unmanned ground vehicle (UGV) developed by Qinetiq and designed for reconnaissance, surveillance, and target acquisition (RSTA) missions to increase the security of personnel manning forward locations.
What are Maars in geography?
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption (an explosion which occurs when groundwater comes into contact with hot lava or magma). A maar characteristically fills with water to form a relatively shallow crater lake which may also be called a maar.
Who made the maars robot?
Which best describes a Phreatomagmatic eruption?
Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water. They differ from exclusively magmatic eruptions and phreatic eruptions. Unlike phreatic eruptions, the products of phreatomagmatic eruptions contain juvenile (magmatic) clasts.
Where are Plinian eruptions found?
The 79 AD eruption of Mount Vesuvius in Pompeii, Italy. It was the prototypical Plinian eruption. The 180 AD Lake Taupo eruption in New Zealand. The 1600 eruption of Huaynaputina in Peru.
How is the Maars robot taught to perform its task?
How is the robot taught to perform its task? It uses U.S. SOCOM and army lessons to do its task in other words it learns from it.
