What is the difference between physical process and chemical process?

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

What are some examples of physical processes?

Examples of Physical Changes You See Every Day

  • An ice cube melting into water in your drink.
  • Freezing water to make ice cubes.
  • Boiling water evaporating.
  • Hot shower water turning to steam.
  • Steam from the shower condensing on a mirror.

What are the physical processes?

There are four physical systems: the atmosphere, the biosphere, the hydrosphere, and the lithosphere. The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth’s surface.

What are external physical processes and what is their effect?

External processes shape the relief created by internal processes. External agents carry out this process: water, ice, wind, atmosphere and human beings. They include all the changes that alter or wear down the rocks and deposit materials resulting from erosion.

What is internal and external process?

Landform is a natural feature of the earth’s surface. The internal process results in a portion of the earth’s surface getting elevated or getting sunk. External Process: Continuous wearing down and rebuilding of the earth’s surface is the result of external process. Erosion: Removal of materials is called erosion.

What is the difference between internal and external processes?

external processes are the wearing down or destructive proc. that eventually tend to diminish topographic irregularities. Internal processes are constructive, uplifting, building processes that tend to increase the relief of the land surface.

What are the different types of internal and external processes?

External processes work on the surface of the crust through weathering, denudation (or removal of the surface), erosion and deposition (or the raising of land). Some of these works are caused by rivers, glaciers, winds and waves. Internal processes work on the interior layers of the Earth.

What are the two main external processes Why are they called external processes?

External Process: Continuous wearing down and rebuilding of the earth’s surface is the result of external process. Erosion: Removal of materials is called erosion. Erosion results in lowering of the earth’s surface. Erosion is carried out by various agents; like wind and water.

What are the 4 geomorphic processes?

Weathering, mass wasting, erosion and deposition are exogenic geomorphic processes. These exogenic processes are dealt with in detail in this chapter.

What are internal processes?

Internal process – a process that shapes the earth with forces from the interior of the earth. Note: Internal processes are known as endogenetic process in pre-DSE syllabuses, which you need to know when you do past papers. The three forces are compressional force, tensional force and shear/lateral force.

What is the internal process model?

Model 3 of 4: Internal process model Means: Information management and communication. End: Stability and control. Focus: Internal. The internal process model is a more controlling approach that aims to achieve continuity and consolidation of past achievements.

What are internal processes and what do they cause?

Answer: The earth beneath your feet is continuously moving. The movement of earth’s surface results in internal process. The internal process results in a portion of the earth’s surface getting elevated or getting sunk. they cause earthquakes, volcanic activities and mountain buildings.
