What would you be most likely to find at a divergent boundary between two pieces of continental crust?
GeologyAsked by: Jay Betoch A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundariesplate boundariesIf two tectonic plates
How are U shaped and V shaped valleys formed?
GeologyAsked by: Suzanne Gerrans Valley glaciers carve U-shaped valleysU-shaped valleysU-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. How are U-shaped valleys formed simple? Glaciers cut distinctive U-shaped valleys , or troughs, with a flat floor and steep sides. The
How did the Himalayan mountains form quizlet?
GeologyAsked by: Andy Singh The Himalayas were formed due to the collision between the Eurasian Plate and the Indian Plate. When Asia and Europe collided, subduction stopped because India could not sink into the mantle. Since it could not sink, the Indian Plate pushed the crust upward and also downward, because of this, the Himalayas
What is the process which causes magma to form?
GeologyAsked by: Nicole Young Magma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The upper part of the lithosphere (crust) is a poor heat conductor, so the temperature remains about the same throughout the underlying mantle material. What causes magma to form?
Why are the Appalachian mountains so important?
GeologyAsked by: Jesse Carmody The mountains have played an important role in the history and economic development of the United States. They formed a barrier that held the early settlers near the Atlantic coast until the colonies could develop the unity and strength to fight for independence and form a nation. What makes Appalachia unique?
What causes mass wasting?
GeologyAsked by: Joseph Fulce Mass-wasting events are triggered by changes that oversteepen slope angles and weaken slope stability, such as rapid snow melt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, stream erosion, and human activities. Excessive precipitation is the most common trigger. What triggers mass wasting? Mass-wasting events often have a trigger: something changes
What is the interaction between the atmosphere and hydrosphere?
GeologyAsked by: Malaysy Bottenhagen Plants (atmosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. Plants (hydrosphere) draw water (biosphere) and nutrients from the soil and release water vapor into the atmosphere. What is the interaction between the atmosphere and biosphere? Biosphere-Atmosphere Interactions focuses on the sources and sinks
At what depth does the earth heat up?
GeologyAsked by: Ryan Mence The geothermal gradient (i.e. the increase in temperature with an increase in depth in the Earth) is not equal all over the world. On average, the temperature increases 2°- 3° C per 100 m in depth, however the increase can range from 1° to 5° C/100 m. How far into the
What’s the difference between sinkholes and subsidence?
GeologyAsked by: Adam Jaye In simplest terms, land subsidence is a lowering of the ground while sinkholes involve a collapsing of the land and usually creating a giant hole. What is the difference in collapse versus subsidence sinkholes? Karst subsidence is sinking of land that occurs as a result of gradual dissolution of soluble surface
Where are the active volcanoes in the Philippines located?
GeologyAsked by: Kara Gilbert Most of the Philippines’ active volcanoes are found on the island of Luzon, which is the largest and most prominent island in the Philippines. Aside from MayonMayonMayon is the main landmark and highest point of the province of Albay and the whole Bicol Region in the Philippines, rising 2,463 meters (8,081
