<p>Mass wasting is the removal of rock from its location as a result of gravitational forces.</p> Signup and view all the answers

<p>Factors that affect the type and amount of mass wasting include slope steepness, the presence of plant roots, and the amount of water present.</p> Signup and view all the answers

<p>Mass wasting occurs more easily on steeper slopes.</p> Signup and view all the answers

<p>Plant roots hold soil in place, so mass wasting often occurs after forest fires when the roots are burned.</p> Signup and view all the answers

<p>A moderate amount of water holds soil grains together, decreasing mass wasting. However, too much water can cause mudflows and increase mass wasting.</p> Signup and view all the answers
