GEOLOGY

Detailed explanation-1: -Clastic sediment particles usually have worn surfaces and rounded corners caused by physical abrasion during erosion and transport. After rock fragments have been weathered out of outcrops, they are transported to new locations.

Detailed explanation-2: -Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.

Detailed explanation-3: -Typical members of this important group of rocks are conglomerate, sandstone, siltstone, shale, and claystone. The classification in the main types (sandstone, siltstone, and claystone) follows the grain size classification for clastic sediments (Fig. 1.3).

Detailed explanation-4: -Conglomerate. Conglomerate rock is a type of sedimentary rock. It composed of large, rounded rock fragments contained within a smaller grained matrix of sediments.

Detailed explanation-5: -Examples of Clastic sedimentary rocks include sandstone, shale, siltstone, and breccias.
