The Olympic National Park is one of the most diverse national parks in the United States. The Olympic National Park has three main regions including the Pacific coastline, alpine areas, and the forest. The three basic ecosystems are the sub-alpine forest and wildflower meadow, temperate forest, and the rugged Pacific Shore. The park covers nearly 923,000 acres of wild land, including 60 known glaciers, 73 miles of coast, and 3,000 miles of rivers and streams. The Olympic National Park is located

been salty for a very long time just a little bit after the water permeated the surface of the earth. There are many different theories about where the salt came from. Three of them are volcanic vents, rock erosion, and evaporation. Volcanic vents are subaqueous and can put out heat over 700℉. This means most of the rocks around the vent will melt and release their minerals inside. Most of the salt in the ocean that is not in the water settles on the bottom and combines with the rock. Volcanic vents

the lithosphere, where the brittle, upper portion of the mantle meets the Earth’s crust. The melted rock, known as magma, often pushes through cracks in the crust to form volcanoes. Hot spot volcanism is unique because it does not occur at the boundaries of Earth’s tectonic plates, where all other volcanism occurs. Instead it occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long

My claim on how I fit in the geosphere is that we need paleomagnetism to be able to tell directions and even more. Paleomagnetism is about magnetism in the earth’s rocks which makes up earth’s magnetic field. The earth’s rocks are three compositional layers which are crust, mantle, and core. “...that the molten outer core is the source for Earth's magnetic field.” (pg.85) This is the main thing for the magnetic field for Earth. By having the magnetic field we fit in the geosphere because that helps

The sedimentary record is the best archive of basin-forming tectonics and structural processes, particularly in regions with complex tectonic history such as the Eastern Cordillera in the Northern Andes of Colombia. Multiple tectonic episodes have driven fault reactivation and sedimentation in the Cenozoic is related to contractional strain. Sedimentary basins within the Eastern Cordillera contain coarse and fine grained units. The presence of coarse grained units in the distal regions of a foreland

1. Describe the rock cycle in your own words. The rock cycle is the process in which rocks are created, change their shapes, and eventually are destroyed. 2. Tell what subduction is, and describe what occurs along subduction zones. Subduction is what occurs when two tectonic plates collide and one plate slips under the other tectonic plate. When this happens the bottom tectonic plate fall into the mantle of the earth and be melted to make room for new tectonic plates. 3. Describe in your own words

The Rio Grande rift is superimposed on a region with a long and complex history of deformation and heating, which affects the location and com- position of the subsequent rift-related magmatism (Mack, Seager, Kieling, 1994).. The development of the Rio Grande rift formed part of a series of Cenozoic extensional events that affected the whole of the western USA. These events were contemporaneous with changes in motions of the Farallon and North American plates at the Pacific margin and are widely

Home to hundreds of marine life species off the coast of Florida’s blue waters and accessible only by boat, the seven small islands are known as the Dry Tortugas provide the country with an aesthetically pleasing National Park. This picturesque landscape provides visual amenities such as coral reefs, bird habitats, and the great Fort Jefferson. However, it took a considerable amount of time, weathering, and human intervention to shift and shape the park to its modern day structure. Starting some

Why is the earth not getting larger? Poll some of the answers from the learners and begin the session. Convergent Boundary:(30 minutes) Another type of plate tectonics (when the plates crash into each other), is called convergent. This causes the earths crust to be pushed into the earths interior where it is remelted at the same rate the new crust is being made. Convergent boundaries have two kinds of surface features associated with them. With oceanic convergence a deep ocean trench is formed along

Furthermore, the deep-sea vent hypothesis aims to explain the origin of life on Earth. (i fixed bc awk) Deep undersea vents are often hosts to rich microbial communities. In Hydrothermal vents and the origin of life, William Martin, John Baross, Deborah Kelley, and Michael J. Russel (2008, p.805) note, “the presence of H2 and CO2 near hydrothermal vent systems and surrounding prokaryotic autotrophs may hold clues for the chemistry of the origin of life.” The environment of hydrothermal vents are
