The heating causes rocks like granite to expand. As temperatures fall, the rocks cool down and contract. Continuous expansion and contraction cause pressure on the outer layers of the rock. Cracks develop as a result, and eventually, the outer layers of the rock wear off. This is also known as exfoliation.

Rocks are very tiny grains of different minerals, compressed together in a chemical reaction to form a larger mass. Rocks make up the non-water part of the earth's crust. A mineral and a rock do not mean the same thing. A mineral is made up of an individual element or a combination of elements. It has the same substance throughout.
· What is Erosion? When you stand at a vantage point of space, you'll be treated to an array of breathtaking landforms. However, these beautiful pieces of nature can only qualify as landforms if nature created them. This means human-made dams, vehicles, and buildings cannot be called landforms. Mountains, hills, plains, plateaus, beaches, sea stacks and ...
Positive Effects Of Volcanoes: One of the interesting things about the Volcanic eruptions is the beauty that it exhibits. It helps to create tourism around that area and create more jobs. Volcanoes also provide nutrients to the surrounding soil. Ash from the volcano contains minerals which could benefit the plants.
· What is the Greenhouse Effect? A greenhouse is a house made of glass that can be used to grow plants. The sun's radiations warm the plants and the air inside the greenhouse. The heat trapped inside can't escape out and …

The types of rocks found below the surface depend not only upon the minerals present in the parent rock, but also upon the composition of the ground above. A part of the earth where granite is abundant causes different metamorphic changes than one with sand because granite is heavier and creates more pressure.
· Here we will discuss the causes, effects, and solutions of overpopulation. Growing advances in technology, improvement in the medical sector, quality of life, immigration, etc. are some of the major causes of the growing population in the world. With each year, the population has been increasing, which has affected human life in many ways.
Once these rocks become re-exposed to water and air, the sediment transport process can begin again. Sediment and Geomorphology. Geomorphology refers to both the surface of the Earth (terrain), and the processes acting on it (e.g. wind and rain) 22. As defined earlier – sediment is the collection of particles that can be carried away by wind ...
· Rapidly moving stormwater, flashfloods, and flooding may also occur because of excess surface water runoff, thus, causing extreme local erosion by plucking bed rocks, forming rock cut-basins, creating potholes, and washing away the loosened soil particles. Rivers and Streams; The flow of rivers and streams causes valley erosion.
· What Are Causes and Effects of Volcanoes? Volcanoes are caused by movement of tectonic plates within the earth's crust or along ocean floors, and produce primary and secondary effects upon eruption. Volcanoes may form when tectonic plates move away from one another, or when they collide. Volcanoes form on land and beneath the sea.
Professor Kaoru Ishikawa created Cause and Effect Analysis in the 1960s. The technique uses a diagram-based approach for thinking through all of the possible causes of a problem. This helps you to carry out a thorough analysis of the …
· The dynamic behaviors of calcareous sand were investigated under undrained conditions using cyclic triaxial tests, and the results were compared with those of commercially available Fujian (Fj) sand. The test results were used to evaluate the effects of gradation, particle crushing, and other parameters on the liquefaction resistance. The results of the undrained …
· Fig. 2 shows the linear and double logarithmic curves drawn based on Eq.. In ordinary linear space, two different behaviors of linear and non-linear (power function) are visible (Fig. 2a).However, in logarithmic scale (Fig. 2b), a line with a slope equal to cot −1 n exists for each state.Therefore, n value can specify the governing creep behavior. The creep behavior follows …
