Webminerals coating the sediment grains and gluing them together into a fused rock - cementation Place these clastic sedimentary rocks in order from smallest grain size (1) to largest grain size (4). claystone - 1 siltstone - 2 sandstone - 3 conglomerate - 4 Put the sediments shown below in order according to how well sorted they are. WebThere are two main types of chemical weathering. On the one hand, some minerals become altered to other minerals. For example, feldspar is altered — by hydrolysis — to clay minerals. On the other hand, some minerals dissolve completely, and their components go into solution. For example, calcite (CaCO 3) is soluble in acidic solutions.
