The three main examples of constructive forces are crustal deformation, volcanic eruptions and deposition of sediment. Constructive forces are the processes that build land formations. These formations include mountains and sedimentary rock layers.
Crustal deformation refers to changes in the shape of the land, typically as a result of collisions between the Earth's plates. Volcanic eruptions are openings in the Earth's crust that allow for the release of molten rock. This rock, called "lava," turns into landforms of igneous rock after cooling. Deposition of sediment is the process in which loose particles are compacted into hard layers of sedimentary rock.Learn More
Mass movement refers to the relocation of surface material resulting from gravity. The most common types of mass movement are landslides and rockfalls; these types of movements are very sudden. Other forms of mass movement include slump, rockslide, debris slide, flow and talus. Weathering and erosion are the major contributors to mass movement processes.Full Answer >
Gold and platinum are the most ductile metals on the periodic table of elements. Metals like copper, iron, nickel, manganese, silver, iridium, osmium, tungsten, tantalum, hafnium, rhenium, tin and zirconium can be drawn into very long wires. An ounce of gold can be drawn into a wire 50 miles long.Full Answer >
Purple needlegrass, buffalo grass, asters, clovers, cottonwoods and willows are all types of vegetation that may grow in a temperate grassland. Temperate grasslands are composed primarily of grasses. Flowers grow among the grasses, and a few trees may grow in river valleys.Full Answer >
Naturally occurring structures include canyons such as the Grand Canyon in the United States, mountains such as Mount Everest, and even homes and nests that animals make for themselves, including beehives, ant hills, bird nests and beaver dams. Any form that stands on its own and has a definitive form that was not made by man is considered a natural structure. This is in contrast to man-made structures like buildings and bridges.Full Answer >
