1. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
2. Landslides are geologic phenomena that can happen suddenly or through imperceptively slow downslope movement. ... A "translational" landslide can happen rapidly and result in all of the soil on a hillside being stripped off and filling the area at the bottom of the slope.
3. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.
4. The Uplift of the Colorado Plateau. The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. ... The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down.

Rather, it appears to be quite typical of the almost innumerable galaxies in the observable universe. The fact that black holes may be the rule rather than the exception makes it even more important that we continue to study them.</span> </span><span> <span> </span></span></span>

Explanation:
in a semi-permeable membrane, very specific amounts of materials are allowed through. This is particularly helpful in the human body because the body can then create "charge differences" between ions. In these charge differences, neurons can fire and pretty much all movement in your body is achieved because of these membranes. They are also called selective membranes
