What is the sequence of events that form clastic sedimentary frocks from solid rocks?
The formation of a clastic sediment and sedimentary rocks involves five processes: 1. weathering 2. erosion 3. transportation 4. deposition 5. lithification
What can slow or prevent erosion by water?
It is big subject and answer could be 2-3 chapters: Water related erosion can be prevented by: 1. Creation of check dams. 2. Lining and check dam creations 3. Across the slop furrowing 4. Vegetation at the steep slopes 5. Trees to prevent erosion cause by rain 6. System to get water seeping at subsoil level.
How do streams carry their load?
Stream erode their channels by abrasion, grinding, and by dissolving soluble material. Stream transport sediment in three ways.1. in solution (dissolved load)2. in suspension (suspended load)3. scooting or rolling along the bottom (bed load)Hope that helps. Lot of people trolling this days...Please do not delete.
What 3 ways can coating improve a painting surface?
Rusting , Corrosion & Looks
What are 3 ways to create Emphasis in a work of art?
Directional Lines, Contrasting Values, Placement and Size are all ways to create emphasis in art.
What is a wash?
1. The dry bed of a stream 2. Waste water 3. The erosion of sediment or sediment that has been eroded
What are the 3 steps of a longshore current?
Wave energy moves water and sediment up the beach at an oblique angle. Gravity pulls the water and sediment back down the beach in a straight line. This creates a current that flows parallel to the shoreline, known as a longshore current.
What is wash?
1. The dry bed of a stream 2. Waste water 3. The erosion of sediment or sediment that has been eroded
What are the disadvantages of groins?
1. short term 2. dangerous to surfers 3. Not visually appealing 4. prevents sediment going up the beach, this sediment is used to prevent erosion, and it can lead to structures that are formed by erosion to be formed. i.e the collapse of cliffs and the creation of caves, arches and stacks.
North American landmark which moves backwards?
Niagra Falls due to the erosion of the earth beneath the falls. It moves back about 3 feet each year.
Identify 3 examples of erosion?
Coastal erosion: where waves and currents wear away shorelines over time. Riverbank erosion: where flowing water gradually removes soil and sediment from the banks of rivers. Wind erosion: where wind carries and deposits soil and sediments, causing changes to the landscape.
What are the 3 main things that cause Erosion?
The three main things that cause erosion are water, wind, and ice. Water erosion occurs from rivers, rainfall, and waves, while wind erosion happens when wind displaces soil and sediment. Ice erosion occurs through processes like glaciers moving over land.
How does an unconformity formed?
1) Deposition of sediment 2) Rocks are uplifted and eroded 3) Erosion of strata 4) New rock is laid down on top of older rock 5) Uplift and erosion exposes the unconformity at the surface
How how does an unconformity form?
1) Deposition of sediment 2) Rocks are uplifted and eroded 3) Erosion of strata 4) New rock is laid down on top of older rock 5) Uplift and erosion exposes the unconformity at the surface
Why does a river deposits its load?
the 3 ways are:1) solution2)suspension3)bed load
What is 3 of the major agents of erosion?
Three major agents of erosion are water, wind, and ice. Water erosion is caused by rivers, streams, and rainfall washing away sediment and soil. Wind erosion occurs when strong winds move and transport particles of soil and rock. Ice erosion, or glacial erosion, happens when glaciers or ice sheets erode the land as they move and slide over the surface.
What happens when fast water flows?
the faster it moves the more soil it pushes away in 3 processes of erosion, transportation and deposition
