What causes mass wasting?
Regional SpecificsAsked 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?
Regional SpecificsAsked 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?
Regional SpecificsAsked 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?
Regional SpecificsAsked 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

Why is Earth’s surface changing?
Regional SpecificsAsked by: James Owens Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth’s plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and
