Wind, water, and ice are the three agents of erosion, or the carrying away of rock, sediment, and soil. Erosion is distinguished from weathering -- the physical or chemical breakdown of the minerals in rock. However, weathering and erosion can happen simultaneously. Erosion is a natural process, though it is often increased by humans' use of the land. Deforestation, overgrazing, Answers.com, and road building often expose soil and sediments and lead to increased erosion. Excessive erosion leads to loss of soil, ecosystem damage, and a buildup of sediments in water sources. Building terraces and planting trees can help reduce erosion.
GLACIERSIn the Arctic and sub-Arctic, glacial erosion has shaped much of the landscape. Glaciers primarily erode through plucking and abrasion. Plucking occurs as a glacier flows over bedrock, softening and lifting blocks of rock that are brought into the ice. The intense pressure at the base of the glacier causes some of the ice to melt, forming a thin layer of subglacial water. This water flows into cracks in the bedrock. As the water refreezes, the ice acts as a lever loosening the rock by lifting it. The fractured rock is thus incorporated into the glacier's load and is carried along as the glacier slowly moves.Another answer
The earth's plates float on a bed of lava and are constantly moving.
1) When one of the earth's plates runs into another plate it causes the dirt to be pushed up and may build mountains.
2) Over time the plates may move into a different climate zone and the plants and animals will have to move, evolve, or die
What else can I help you with?
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
What is the slowest to change earths surface?
The slowest-changing feature on Earth's surface is likely its tectonic plates, which move at a rate of a few centimeters per year. This movement can result in slow changes in topography and the creation of mountains or ocean basins over millions of years.
What process is in animals that are stimulated by the movement of earths continent and oceanic plates?
The process in animals that is stimulated by the movement of Earth's tectonic plates is known as "biogeography." This involves the study of how animals are distributed and how their geographic distribution is influenced by the movement of continents and oceanic plates. Changes in land masses can impact habitat availability, climate, and the migration patterns of species.
Can plate movement alter earth systems and produce changes in earths surface?
Yes, if two plates moved in opposite directions to each other- moving away from each other-, it could create a hole in the ground which would go on, in to the center. Also, (mainly in the ocean) by the movement of two plates moving apart a volcano could be formed underwater.
What do the yellow arrows in this illustration represent in the earths core?
movement of earth's tectonic plates
How does the surface of the earth change when two continental plates collide?
The Earths surface changes shape when plates collide when the earths surface overlaps or when there are Earthquakes.
What are two ways the movement of earths plates changes the earths surface?
The movement of Earth's plates can create geological features like mountains and volcanoes through processes such as subduction and continental collision. It can also lead to earthquakes when plates shift along faults in the Earth's crust.
What theory of the formation and movement of the plates that cover the earths surface?
the movement and formation of the plates or continents is caused by conduction under the crust.
What is the theory of formation and movement of the plates that cover the earths surface?
the movement and formation of the plates or continents is caused by conduction under the crust.
Explain two ways that the movement of earths plates changes the surface of earth?
The movement of Earth's plates can cause earthquakes when plates collide, separate, or slide past each other. Additionally, the movement of plates can create volcanic activity along plate boundaries, leading to the formation of new landforms such as mountains or island chains.
How is an earhquake started?
An earthquake is started when two plates (which lie under the Earths surface) rub together this creates movement which then sometimes pulls/pushes at the earths surface and creates giant cracks in the earths surface... and that is how an earthquake is started.
What are plate movement?
the movement of earths plates or crust
What forces below earth surface shape landforms?
The tectonic plates below earths surface shape earths landforms
How does energy in earths interior cause changes to earths surface?
The energy from the core of the earth causes currents in the molten layers, the way there are currents in the ocean. These currents are what causes the Tectonic Plates to move along the surface of the earth.
How many major plates compose earths surface?
there are 8 plates
What is tactonic plates?
PLATE TECTONICS is the study of the movement of the earths continental plates
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
