orogenic forces are that forces which means block making .they make Block mountains.epeirogenic forces are that forces which are continent making they make continent.

The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.

Before getting into the different types of faults, you must understand the difference between a HANGING WALL and a FOOTWALL. The hanging wall is the block of rock above the fault line. You can hang something from the hanging wall as if it were a ceiling. The footwall is the block of rock below the …

An anticline is a fold that is convex upward, and a syncline is a fold that is concave upward. An anticlinorium is a large anticline on which minor folds are superimposed, and a synclinorium is a large syncline on which minor folds are superimposed.

Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.

There are different types of chemical weathering processes, such as solution, hydration, hydrolysis, carbonation, oxidation, reduction, and chelation. Some of these reactions occur more easily when the water is slightly acidic.

The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions.

Five types of chemical weathering include: acidification, oxidization, carbonation, hydrolysis, and by living creatures or organisms that are on the substance.

The main forms of erosion are: surface erosion. fluvial erosion.

Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
