Geologic Processes




Geologic ProcessesThe word geologic processes explain the natural forces that form the physical makeup of an earth. Plate tectonics, chemical weathering, erosion and sedimentation all are examples of forces which significantly impact the Earthís surface and account for its main features. These procedures are closely analyzed by earth scientists and geologists to improve their knowledge of the planetís history; to aid locate helpful resources, including metal ores and to help the prediction of potentially disastrous activities, for example tsunamis, earthquakes and volcanic eruptions.

Plate Tectonics

When looking at the world from space, it provides an impression of total, immovable serenity. The background of the planet, however, is dominated through the splitting and joining of landmasses to make new continents that change their positions on a continuous basis.

Erosion

When rock is worn away through ice, water or even wind, this is referred to as erosion. It is probably the most important geologic processes and, with time, can change landscapes.

Chemical weathering

Rock can behave with substances present in air or in the water, creating chemical weathering. When rocks that make deep underground are exposed on the top, they may slowly change color and crumble because of iron compounds responding with oxygen within the air, for example.

Sedimentation

Material suspended or mixed in water forms rock by a process called deposition or sedimentation. This can take place through the develop and compaction of tiny particles as they settle out from the water or by evaporation leading to dissolved chemicals to crystallize.

Geology Plate Tectonics

Geologists have an explanation a scientific theory of the way the Earth's surface reacts referred to as plate tectonics. Tectonics signifies large-scale structure. Therefore plate tectonics states that the large-scale structure of the world's outer shell is a pair of plates.

Tectonic Plates

Tectonic plates do not quite match the continents and the seas on the world's surface. The North America plate, for example, extends through the west coast of the U.S. and Canada to the center of the Atlantic Sea. And the Pacific plate contains a chunk of California and most of the Pacific Ocean. This is because the continents and ocean basins are part of the planet's crust. However plates are constructed of hard rock and relatively cold and which extends deeper compared to the crust to the upper mantle.

Geological Processes Examples

The safety of Carbon Dioxide storage depends on the quantification and understanding of a number of geological processes that may increase from the injection of higher pressure fluids into geological reservoirs. Geological processes examples could be the hydraulic fracturing of the reservoir throughout injection and/or dilation of the porous rock matrix, the fingering of mixed CO2/brine combination in the reservoir or the upward porous circulation of the buoyant CO2 plume.

The geological processes, including earthquakes, volcanic eruptions, erosion and deposition are what generate or change geological features. Volcanoes are made by inner forces inside the Earth that result in heated, melted rock to rise to the top. First collecting in magma chambers, a few of the magma eventually forces upward through cracks to the world's surface. As the magma gets to the surface, it loses a few of its gases and becomes lava.
