What Causes Differences In Weathering For Marble

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

What causes differences in weathering for marble.

Plant and animal life atmosphere and water are the major causes of weathering. Let us compare and contrast weathering and erosion in detail. Different types of stone can react in different ways to the same sets of weathering agents and can produce different weathering forms even in the same environment. This marble gravestone has lead lettering similar to that of the john walker memorial.

Ing weathering close attention to individual headstones works well. Weathering causes the disintegration of rock near the surface of the earth. Where is the tate family grave. The primary difference between weathering and erosion in points is given below.

Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water wind and ice. Several different headstones pref erably of different rock types can be studied in detail. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. The two thus provide a useful direct comparison of weathering rates between different lithologies.

Types of weathering there are two unmistakable kinds of weathering which modify and corrupt rock in various manners. Limestone versus marble differences in chemical erosion. Consequently they suffer from different deterioration processes mainly dissolution in rain 1 and thermal weathering 2 in the case of marble and stress from crystallization of ice and salts. Exposure to air or water changes the.

Types of gravestones or environments with particular weathering processes. Weathering occurs when the physical and chemical characteristics of rocks found on the earth s surface undergo change. Drawings or photos of areas of a headstone which show signs of the main weathering processes can be la belled to point out the differences between freeze thaw chemical and. The image on the right shows a close up of the raised lettering on the surface of the grave stone.

Erosion on the other hand causes rocks or particles of rock to be carried away from their original locations and deposited elsewhere. The agents affecting these changes are various components of water found in the earth s hydrosphere or gaseous substances from the atmosphere. Weathering degrades a rock without changing its location. Physical weathering separates a rock s physical structure.
