Petroglyph Photos - Geology

A petroglyph is an image that is carved into a rock. This "carving" can produce a visible indentation in the rock or it can simply be the scratching away of a weathered surface to reveal unweathered material of a different color below. It is not a "drawing" or a "painting" - those are "pictographs ...

gcse 3. Weathering of Rocks - Chemical and Physical ...

The different ways by which rocks are weathered and eroded are discussed e.g. physical weathering by wind, rain, waves, ice, heat from the sun, chemical weathering by acidified run off water and acid rain and biological weathering by plants-roots descriptions etc. Examples of rock formation erosion and associated processes of transportation and deposition are also described.

Types of Stone to Control Erosion | Sciencing

Erosion is the washing away of vital soil and other ground materials in rain or tidal movements. Several different factors can cause erosion, including the removal of surrounding plant life. The effects are the draining away of valuable nutrients from gradient areas, making it difficult for plants to grow, and the ...

Section 1 Weathering - Midway Middle School Science

Abrasion is the grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles. Whenever one rock hits another, abrasion takes place. As Figure 2 shows, abrasion can happen in many ways. Water can cause abrasion as rocks bump into and scrape each other as they are moved by waves and rivers.

Coastal erosion - Wikipedia

Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
