<span>The answer for this question is D. Use the machine to increase the incline and intensity. The reason for this is the fact that increasing the incline will cause her to work against gravity and the increase in intensity will result in her having to work harder. The difference between this and her running speed increasing is the fact that mentally she can determine what her running speed is, but if the machine is at an incline and the intensity is set higher, she physically has no choice but to push her body, thus resulting in a more effective workout.</span>
Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanicaland chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments.
