What process causes the rocks to be at the bottom of the slope?

What process causes the rocks to be at the bottom of the slope?

A landslide is any geologic process in which gravity causes rock, soil, artificial fill or a combination of the three to move down a slope.

What causes rock to be exposed at the Earth’s surface?

Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.

What happen when a rock is exposed to the sun?

Answer: If an igneous rock is exposed to the sun for millions of years it becomes brittle. Then the energy from the Earth’s interior would cause a weathering and erosion effect on the rocks.

What are the weathering processes?

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

Why is sedimentary rock susceptible to weathering and erosion?

Rock and Mineral Type Some minerals in a rock might completely dissolve in water. This leaves behind the more resistant minerals, which are released from the rock. Intrusive igneous rocks weather slowly because it is hard for water to penetrate them. Sedimentary rocks usually weather more easily.

Why are rocks not weathered into sand and mud?

The BEST explanation for this is that the rocks had not weathered into sand and mud on the level area. rain moved sand and mud away from the rocks on the sloped surface. sand and mud are generally found in low places on level areas. rocks prevent soil from eroding from the slope.

Why are there more rocks after a rain?

Q. Students notice after a rain that a construction site showed more pebbles and small rocks exposed on a sloped surface than on a level area which was covered with sand and mud. The BEST explanation for this is that the rocks had not weathered into sand and mud on the level area.

How is the breakdown of rock called weathering?

They consider the breakdown of rock into smaller and smaller pieces through processes that collectively are known as weathering. The specific process that students examine in this investigation is abrasion, the action of rocks and sediment grinding against each other and wearing away exposed surfaces.

What makes the rocks in the subduction zone?

Earthquakes knocked loose undersea muds that raced down the slope into the subduction zone to make these layered rocks, which were scraped off the downgoing slab, part of the process by which continents grow as material is added to their edges at subduction zones. Subduction zones produce an amazing variety of geological features. These include
