Mechanical Weathering. Rock is physically broken down. Smaller pieces have same composition. Chemical Weathering. Rock is chemically broken down. Weathering:. Rocks that are exposed to air, water, changes in temperature and vegetation become vulnerable to weathering.

What type of rock is created when existing rock is changed by heat and pressure?. 3. What type of rock is created when rock is weathered, eroded, deposited, compacted and cemented?. Resistant rocks. = hard igneous rocks e.g. Granite and basalt, which are resistant to erosion. Fairly resistant. = sedimentary rocks e.g. Sandstone, chalk and limestone. Least resistant. = weak sedimentary rocks e.g. Clay and shale. These will erode at a faster rate. CLASSIFICATION OF ROCKS:.
