Realms of Earth

Are mountains randomly distributed on the continents, or do they tend to occur in particular patterns (clusters, linear chains, arcs, etc.)? Some appear in lines and others in arcs 1pt 2. Find Mt. Everest, the highest point on earth. Zoom in enough to see the summit, then pan your cursor around to locate the 8840_______ meters highest point (elevations shows up in the status bar at the bottom, as long as View/Status Bar is selected): 1pt Adapted from an activity

Plate Tectonics is a scientific theory which study how the Earth’s plates are driven and shaped by geological forces to keep them in constant movement. The theory explains the present-day tectonic behavior of the Earth, particularly the global distribution of mountain building, earthquake activity, and volcanism in a series of linear belt. (Pitman, W.C., 2007)

9- Mountains: a large natural elevation of the earth's surface rising abruptly from the surrounding level; a large steep hill. A giant lump in the earth.

Erosion is a process where natural forces like water, wind, ice, and gravity wear away rocks and soil. Erosion occurs at the Earth’s surface, and has no effect on the Earth’s mantle and core. Water erosion is the removal of soil particles by heavy rainfall or running water. “While the causes of erosion by water are generally natural, water erosion is usually caused by rainfall and runoff on a slope” (GEI Works Erosion Pollution). “The process of water erosion usually occurs on stream and river banks, sea shores and seaside cliffs” (Reference.com).

For example, The appalachian Mountains were formed by a massive continental collision over 300 million years ago. According to page 88 in my science notebook, the rocks in the Chattooga River is evidence of the continental collision. Mountains are formed when two continental plates collide, and form the mountains. The Appalachian mountains, were formed during Pangea. The North American Plate and the African Plate collided. When this happened the Appalachian Mountains were formed. These mountains then grew bigger, but as soon as it started growing, it also eroded. Erosion and

Cenozoic sedimentary rocks predominated to the west and east of the central mountain while plutonic rocks predominated in the peninsular ranges. The irregular contact between these geologic regions reflects the ancient topography of the area. The ancient oceanic crustal plate created an archipelago of a volcanic island. The former's subduction created immense volumes of magma. This resulted to the congealation of plutonic rock in the crust. The local rocks that existed before the tectonic forces uplifted, and erosion capped the deeply buried plutonic rocks that formed a steep and rugged mountains coastline, similar to that present one, which in the west coast of south America.

Soil Erosion - When the top layer of soil is worn down due to too much water, ice, or wind.

Plate tectonics are very dangerous when they collide,slide,and move apart. They can create mountains like the Appalachian Mountains that used to tower over everything then erosion took place. The Appalachian Mountains were formed by convergent boundaries, convergent boundaries are collide

Convection currents may bring magma to the surface at diverging boundaries. Sedimentary rocks from the ocean floor gets pushed down to the mantle at convergent boundaries. The crust soon melts and rises to the surface creating igneous rock. Typically mountain ranges are metamorphic rock, maybe our mountains are.

Geological forces by the continental plates created the Appalachian and Rocky Mountains. The continental plates collided with each other, forming mountain chains.

    The first, geo-processes is a volcano. Volcanoes happen when when the plates underneath the volcanoes move creating the the magma to push up until the pressure is too much and it erupts. Scientists have an idea that the volcano is going to erupt soon when earthquakes happen near the volcano. A volcano creates mountains and mountain ranges. The article The Hills Are Alive talks about the movement under the volcano. “While the volcano was inactive, the land on top of it was being pushed together by surrounding geology keeping the magma bubbles sealed”. That quote shows how the land was moving closer because of the plates underneath.

The Appalachian Mountains were formed an estimated 480 million years ago, being one of the first plate collisions constructing the supercontinent Pangea. During the Paleozoic Era, the region was submerged, layers of sediment and carbonate rock began to form on top of the already submerging sea bottom. In the Ordovician Period, the Appalachian passive margin evolved into a plate boundary when another plate collided with and sank the North American plate, creating the Appalachians. The Mountains continued to form as volcanoes grew, plate collisions, all while the supercontinent formed. Pangea began its separation 220 million years ago, halting the creation of many mountain ranges. The Appalachian Mountains had almost flattened completely out,

Earthquakes, volcanoes, mountains and the Earth’s crust are unique yet have one common denominator; the amazing topic of plate tectonics. Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following, Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within the Midwest region of the United States. A discussion of various geological events and the types of rocks that formed because of these events will also be covered including the importance of the economic value of these rocks to the Midwest region

The moraines is a “general term for glacier-deposited landforms composed of till” (526). The features usually are irregular and is normally longer than wider. The three types of moraines in glacial deposition of ice sheets are terminal, recessional and ground. Terminal moraine is the front part of a glacier where all the power is. Although glaciers may appear to stop moving forward, the internal part of the glacier continues to give strength to its movement. Recessional moraine is right behind the terminal moraine where the ice would spread out putting pressure out to the edges in bulges. The last type is called ground moraine and that is when “large quantities of till are laid down from underneath the glacier rather than from its edge” (527). A feature we see from the glaciers deposition is an “elongated hill” (527) called a drumlin. These long, small hills that are usually in groups, are much smaller than moraines but still made predominantly of

When collisions between plates occur, the crust is pushed up sometimes forming ranges of mountains. This is the way that most
