Figure 1) A) Rock Fall B) This image is depicting a rock fall, there are huge boulders on the bottom of the area blocking the road. There is no water so it seems to be a free fall of rocks from the top of this mountain region, and fell to the road on the bottom with the influence of gravity. Figure 2) A) Creep B) This image is showing the trees creep, because their trunks of are bent. This landscape is tilting so the trees are following the same thing so in turn they are bent from the bottom. Figure 3) A) Debris Flow B) I chose debris flow because there are huge boulders with mud or water under it. It seemed to also have a path where it came from going downhill. Debris flows usually have lose rocks, soil, and water coming downstream as a
...e morphed it into the quartzite that is seen surrounding the butte (4). Rocks that undergo this process are called metamorphic rock, which is the same as the rock seen years ago by dinosaurs and other extinct creatures. The quartzite rocks were formerly seafloor sediment that was forced upwards, and then surrounded by lava basalt flows. Once erupted through fissures and floods through out most of the area, lava flow eventually created enough basalt to form a thickness of about 1.8 kilometers (1). All of this basalt flow eventually led to the covering of most mountains, leaving the buttes uncovered. The igneous lava flows and loess is reasons that the Palouse consists of such sprawling hills, and rich soil for farming (2). In result of the lava flows, the Precambrian rock Quartzite was formed. And lastly covered by the glacial loess, which were carried by the wind.
There is a lot of repetition of the vertical lines of the forest in the background of the painting, these vertical lines draw the eye up into the clouds and the sky. These repeated vertical lines contrast harshly with a horizontal line that divides the canvas almost exactly in half. The background, upper portion of the canvas, is quite static and flat, whereas the foreground and middle ground of the painting have quite a lot of depth. This static effect is made up for in the immaculate amount of d...

When a river flows downstream it frequently encounters obstacles and changes in the river channel that form “rapids, particularly turbulent water with a rough surface. Rapids also form where the channel abruptly narrows or its gradient changes, suddenly accelerating the water.”(Marshak, 2009) These changes in the dynamics of the river flow create the rapids that modern day thrill seekers look for.
So this leaves one to ask, how do those pesky rocks get thrown at a windshield? If it is hit by the following car, then it is because the rock was thrown somewhat vertically, slowed down by air resistance and the car behind it ran into the rock.
Tree itself is already a very commonly used symbol in many places, it symbolize sheltering, evocative of enternity, rooted in earth and reaching up to the sky and many more. In this book however, it focoused on the growing of the tree, we all know that it takes a lot of time for a tree to grow, likewise, it took a long time for melinda to speak up and face the truth. Moreover, this drawing of the tree is representing the mind growth ofMelinda, for inctense, the drawing was poorly done at the beggining, Melinda’s presure and her life is weighting her down, as the drawing gets better throghout the school year, Melinda’s strength and mind set is getting better too. If the tree ment sheltering, then Melinda sure developed a very nice shelter for herself in the
Global climate change and intensifying temperatures over the past several decades have resulted in shifts in vegetation distribution. With increasing temperature and water deficits, this brings along with it, tree mortality. Tree mortality and environmental changes is the perfect recipe for a change in forest and woodland composition. Bottomland trees such as some oaks and the Magnoliaceae family can’t live in these changing areas anymore and die out. They are found more often by streams or some form of water, where these plants can stay hydrated most the year. The species that regenerate from the light gaps left behind after the dieback are more hardy trees that can handle more dry and hot temperature for longer periods of time.

The painting Olive Trees, now at the Minneapolis Institute of Arts, is one of a series of ten or twelve paintings of olive orchards, which Van Gogh painted in 1889 while living at the asylum of Saint-Remy. This painting is a landscape accomplished in bright, complementary colors, with Van Gogh’s characteristically brisk brushwork. The image is divided roughly into thirds, with the middle zone, the trees, being highly capricious. The brushstrokes describe the lay of the land, the movement of the wind in the trees, and the rays of the sun. The sun itself is hugely misrepresented in size, and highlighted also by an outline of orange. It dominates the picture and takes on perhaps a “supernatural” aspect, possibly representing deity or faith. The curved trees all lean, even quiver, away from the center of the painting. They cast violet shadows which shouldn’t be possible, given the placement of the sun: Realism is sacrificed for the content. The most prominent of these shadows is at the center of the foreground, and is not associated with any one tree. One could see this central shadow as the thing from which the trees are bending. The base of each tree is painted with red lines that ambiguously outline where the shadows would fall if the sun were directly overhead. Both the ground and the trees have a singularly wave appearance, while the sun is more stable, and the distant mountains are still.
look-out points allowed us to observe the incredible speed at which the water rushed over the rock. The water flows at an amazing 212,000 cubic feet of water per second. We were also guided to the basin where the falls originated miles away. In fact, over the last 12,000 years, the falls have eroded back seven miles. The incredible history of the falls came to life when I actually viewed them with my own eyes. No schoolbook could possibly give an understanding of the vastness of the falls. Nor could a book bring to life the remarkable history behind this amazing wonder of nature.
rock sliding down a mountain side or a cliff. And how does an avalanche occur,
Rock mechanics is a discipline that uses the principles of mechanics to describe the behaviour of rock in different engineering scale level. Usually for engineering projects (slopes, tunnels and foundations), the scale ranges from a few tens to a few hundred meters. At engineering scale, rock is said to be inhomogeneous, discontinuities, anisotropic and non-linearly elastic. Besides that, rock mechanics also deals with the response of rock when the current boundary condition is disturbed; for instance, excavation of a tunnel in the ground, the in-situ stress of the rock is disturbed.
The basic chemistry behind a slab avalanche is when one layer of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to break free from the lower layer. The formation of a slab is possible in many ways. One way is for the snow to develop a crust and then there be more snowfall. Since snow doesn’t bond to the crust it becomes a potential for an avalanche zone. Another way is for surface hoar to develop, or large ice crystal on the snow. This is usually caused by condensation on the snow surface. This will also have poor bonding characteristics, and cause for a potential slide. The crystal itself is also very stable and will stay in that formation until melted usually. Slab avalanches usually only occur between 35-45 degree slopes and on a concave slope. There are ways possible to test for an avalanche zone. These tests have been developed over the years by ski patrollers, avalanche safety, and seasoned mountaineers. Make sure whenever performing an avalanche test you are not in an area where you could possibly trigger or be in the path of an avalanche.
Avalanches are large amounts of snow, ice, and rocks rapidly moving down a mountainside. They can have many causes, some are natural and others are artificial. Some examples of natural avalanche causes include new rain or snow; these can in fact cause a cluster of snow to suddenly dislodge and downpour on a mountainside. Earthquakes and the natural movement of animals are also known to have caused avalanches in the past. The movement of the animals or earthquakes slowly or rapidly moves the snow until it is moved so much that it becomes loose and again runs down a mountainside. Artificial triggers consisting of things like snowmobiles, skiers, gunshots, and explosives. Avalanches usually occur during the winter and spring, as they are
