Explain Why Weathering Does Not Produce Significant Landforms

Out wash has small sediments sorted in layers, and Till has large sediments not sorted into any layers. Till can leave behind features like Kame, Drumlins, and Moraines. Drumlins are elongated hills of till. Drumlins can be found in Central Minnesota and/or South of Brainerd. Moraines are very large ridges of Till. Moraines can be found in West/Central Minnesota. Outwash can leave features behind like Outwash Plains and Eskers. An Outwash plain formed by melt water of a glacier. Outwash plains are important because they are very great for farming which is a huge part of America. Glaciers can leave behind features like Kettle Lakes. Kettle Lakes formed by ice chunks falling off the main glacier, causing an indent on the earth's surface. Then the ice chunk will melt causing the hole to fill up with water. Most of Minnesota’s Kettle lakes are in Moraine/Terminal Moraine

In site one there was a high proportion of very unspherical rocks. According to this the hypothesis is right, in site two there is a lot more smother rocks medium sized and in site 3 there are very small pebbles which are very smooth and spherical. The pebbles get smoother and rounder while it goes downstream. Due to us only taking about 10 rocks our result may have been not right as there were some pebbles which were largely over sized. Most of the other load is dissolved by solution such as limestone and chalk

A smooth mountain rock surface enhances runoff because it is freeway passage without any chance of retaining any sediments. Other rough rock surfaces alternatively hinder runoff by retaining materials thus less runoff.

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).

There are coarsening-upward sequences preserved, with flooding surfaces represented by low-relief erosional contact of trough-cross-stratification (runnel) upon low-angle planar bedding (swash zone).

Outwash and till are similar but different at the same time and this is why they are both deposited by glaciers, but the way they are deposited is what makes them different. Till is simply the sediment left by the ice, outwash is deposited by the running water coming off of the melting glacier. Because water can sort sediment, and ice cannot, that is why the till is unsorted. Sorting just means when the rocks are sorted by size, bigger pieces together on the bottom, smaller pieces together on top. Glaciers are constructive and deconstructive they are deconstructive because they tear up land and the glacier does not stop for anything but it is easy to avoid. Glaciers erode the land and create landforms such as kames, eskers, and drumlins those terms will be explained a little bit later. Glaciers create valleys by shearing away the mountainside and moving it away. Some of the landforms that glaciers produce are drumlins, terminal moraine, outwash plain, and an erratic. Drumlins are elongated, teardrop-shaped hills of rock, sand, and gravel that formed under moving glacier ice. A terminal moraine is where the glacier reaches its max and starts receding making a deposit of till. An outwash plain is a flat area made by meltwater carrying outwash from the leading edge of the glacier. An erratic is a rock or boulder carried from a place where the Rock is common to an area where the rock is not

To support the theory of continental drift is through topography, surveying the floors of oceans, charts of rock magnetism, and statistics on rock ages (Trefil & Hazen, 2010). At one time scientist believed that the deep ocean floors were flat; accumulating the sediment that progressively wore away from the prehistoric landmasses (Trefil & Hazen, 2010). However, they discovered steep-walled valleys and elevated highlands. This was evidences that just as the continents are transformed and are active, so to is the seafloor (Trefil & Hazen, 2010). The Mid- Atlantic Ridge, positioned in the central part of the Atlantic Ocean, is recorded to be the longest mountain range on this planet. Volcanoes, lava flow, and earthquakes are a source of

Environments where sediments are elated and deposited quickly are high energy environments like ocean shores, or rushing rivers. Eco systems where small particles of sediments are often deposited in low energy areas. This is found in regions where there are deep lakes or swamps. Landforms shaped by erosion are tall, jagged structures with grazes in layers of rock and landforms produced by deposition are flat and low lying. Landforms created by deposition are alluvial fans, sandbars, moraines, eskers, and deserts. While landforms created by erosion are mountains, valleys, hoodoos, sea arches, sea caves, plains, sea cliff and

As this river of ice moved slowly over the hidden rocks, the base of the glacier grazed millions of sediments in the Earth. The after math composed of soil, pebbles, cobbles and boulders that pushed forward, smashing rocks into glacial dust. Then the climate began to warm. Melted water from the glaciers carried the soils and rocks away from the dissolving glacier, depositing its leftovers throughout the landscape. This combination of soils and rocks deposited. Then low hills, or moraines, were created across the state. Michigan's glacial drift averages 200 to 300 feet. The scraping of boulders created particles. The heaviest pieces formed ridges, which made the stream's flow in a certain direction. Lighter materials were carried further, dropping on the way as the flowing water slowed. These materials dried forming enormous, flat colored areas of sand, silt, clay creating a mixture called the outwash plains. The weight of the glacier over the Michigan basin was dropping, and the Earth began to recoil, like a sponge coming back to its original shape. The Michigan landscape began to appear. Plants began to approach on the shriveled landscape. Individual plants found a suitable growing environment near each other, which created a suitable home for

Tectonic plates are the reason why earth's surface area isn’t flat. Tectonic plate formed the Appalachian mountains and Mount Frisell. This happened millions of years ago, and the cause of the formation is that the tectonic plates collide into each other start to rise upwards. This brings up big pieces of rock from the crust to form mountains. Tectonic plate didn’t just form mountains is Connecticut they also form valleys. Valleys are formed by the tectonic plates repelling off each other and creating a big, long valley that could hold water in them. This is one of the steps how the famous Connecticut river was formed.

The tiny pieces of rocks broken off by weathering are called sediment or alluvium. Erosion is the process of transportation of this sediment which on sea cliffs sediments becomes part of the seafloor and is washed away with the waves. The larger rocks that are broken off by sediment as shown in this picture are called scree or talus; scree builds up at the bottom of cliffs as the rocks tumble down, these piles are called scree slopes or talus piles.

Weather is the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind velocity, and barometric pressure. Weather can be classified as day to day temperature and precipitation activity, where climiate is average atmospheric conditions over longer periods of time. Weather occurs from temperature and moisture differences between one place and another. These differences can occur due to the sun angle at any particular spot. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as "extratropical cyclones", are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted

There are 4 main physical systems called biosphere, hydrosphere, lithosphere, and atmosphere. These main physical systems along with weathering and erosion contribute a lot to how earth looks. The biosphere is where all the ecosystems join or the "living area". The hydrosphere is all the bodies of water on earth. This includes oceans, rivers, ponds, and seas. It covers roughly 70% of the earths surface. The lithosphere is the inside layers of earth. Which includes the crust, the hard outermost layer of earth and the upper mantle, the cooler dense layer under the crust. The atmosphere is the air or gasses surrounding earth or a planet. Weathering is the process of breaking down rocks and minerals into smaller pieces. Water, ice, plants, and

HYDROLOGIC CYCLE The hydrologic cycle is a constant movement of water above, on, and below the earth's surface. It is a cycle that replenishes ground water supplies. It begins as water vaporizes into the atmosphere from vegetation, soil, lakes, rivers, snowfields and oceans-a process called evapotranspiration. As the water vapor rises it condenses to form clouds that return water to the land through precipitation: rain, snow, or hail. Precipitation falls on the earth and either percolates into the soil or flows across the ground. Usually it does both. When precipitation percolates into the soil it is called infiltration when it flows across the ground it is called surface run off. The amount of precipitation that infiltrates, versus the

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