What is it called when softer rock weathers away and leaves harder rocks behind


What rocks contain gypsum?

Gypsum is commonly found in sedimentary rocks such as limestone, shale, and sandstone. It forms from the evaporation of water-soluble minerals in these rocks, leaving behind the mineral gypsum as a product.


The soil and rocks left behind by a glacier?

The soil and rocks left behind by a glacier are called moraine. Moraines can be classified as lateral, medial, or terminal, depending on where they are deposited in relation to the glacier. These deposits play a vital role in shaping the landscape and providing insights into glacial history.


What is the force behind weathering by thermal expansion and contraction?

The force behind weathering by thermal expansion and contraction is the repeated heating and cooling of rocks, causing them to expand and contract. This leads to the breaking down of rocks into smaller pieces due to the stress created by the expansion and contraction process.


Why are some intrusive rocks be left behind when rocks are worn away?

Intrusive rocks come into other rocks in a molten state and when they cool they are frequently very hard with interlocking cemented crystal structures. When erosion occurs it is easier for wind, ice and rain to wear down the rocks into which the igneous rocks were intruded than the hard igneous rocks themselves. This leaves the igneous rocks sticking up (like King Arther's Seat in Edinburgh or the Tours of Dartmoore) as prominent features.
