What is 11th weathering?

Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering. It is the breakdown and decay of rocks in situ.

What is erosion and deposition 11?

Erosion, deposition and weathering are the processes which change our earth’s landscape. Gravity can also pull soil and rocks downhill. -Deposition on the other hand, is the process of dropping of sediments that are carried by erosional agents like wind, water and gravity.

Is erosion a gradational process?

Gradational processes Weathering = breakdown of material in place Gradation = leveling of land degradation (erosion) = removal of highs transportation = movement of material aggradation (deposition) = filling in lows Tectonic processes build up of roughen up the earth Gradational forces level off highs and fill in lows …

Which one of the following is an example of Endogenic forces?

Examples. Endogenic forces include earthquakes, mountain formation. Exogenic forces include the tidal force of the moon, erosion.

Which material is affected by hydration process?

Granite. Clay. Quartz.

Why salt is affected by hydration process?

In dry climates, because of high temperature, evaporation exceeds precipitation and hence ground water is brought up to the surface by capillary action and in the process, the water evaporates leaving behind salts in the soil.

Which process is gradational process?

Weathring, mass movements, erosion, transportation and deposition are the various mobile and mighty exogenic geomorphic agents. These agents bring the geomorphic changes on the surface of the earth.

What are the main constituents of granite?

The chemical composition of granite is typically 70-77% silica, 11-13% alumina, 3-5% potassium oxide, 3-5% soda, 1% lime, 2-3% total iron, and less than 1% magnesia and titania.

Is silver a single element mineral?

Name the minerals which are single elements? Answer: Sulphur, copper, silver, gold, graphite are single elements.

What is a constituent of granite?

The principal constituent of granite is feldspar. Both plagioclase feldspar and alkali feldspar are usually abundant in it, and their relative abundance has provided the basis for granite classifications. In most granite, the ratio of the dominant to the subdominant feldspar is less than two.

Is Granite fast or slow cooling?

Granite and granodiorite are intrusive igneous rocks that slowly cool deep underground in magma chambers called plutons. This slow cooling process allows easily visible crystals to form.

What is granite used for and why?

Granite stone is often used in buildings, bridges, paving, monuments, countertops, tile floors, stair treads and many other design elements. The word granite has been derived from the Latin word ‘granum’ meaning grain.

What is an example of granite?

The definition of granite is a hard light-colored igneous rock used for building and monuments. An example of granite is the rock frequently used in a home’s kitchen counters.

How many uses can you name for granite?

In large construction projects, granite can be used in two different ways: 1) as a structural element, and 2) as decorative facing or veneer.

What do you use to write on granite?

Write with a grease pencil. Write measurements for cutting with a grease pencil or crayon, which can be easily cleaned off with granite cleaner after the granite is installed. Transfer your measurements to the granite using chalk for temporary writing on granite.

Why is granite different colors?

What Determines Granite Colors? Granite is a conglomerate of minerals and rocks, primarily quartz, potassium feldspar, mica, amphiboles, and trace other minerals. The relative proportion of different colored minerals in a granite is largely due to the original source of molten rock that cooled to form the granite.
