Do the minerals that make up a rock determine how fast it weathers?
Yes, the minerals that make up a rock can determine how fast it weathers. Some minerals are more resistant to weathering processes than others, so rocks with more resistant minerals will weather more slowly. For example, quartz is a resistant mineral that can help slow down the weathering of a rock compared to more easily weathered minerals like feldspar.
They type of sedimentary rock that forms when sediments stick together?
The type of sedimentary rock that forms when sediments stick together is called "clastic sedimentary rock." These rocks are created from the compaction and cementation of loose particles like sand, silt, and clay. Examples include sandstone, shale, and conglomerate.
What common school item is made from a sedimentary rock?
Chalk is a common school item made from a sedimentary rock called limestone, which is mainly composed of the mineral calcite.
What would happen to a rock from weathering by a fast moving river?
The rock would likely undergo abrasion, breaking off small pieces and smoothing its surface as it is carried downstream by the force of the fast moving river. Over time, this process can break the rock down into smaller fragments and reshape its overall appearance.
What 2 igneous are formed by fast cooling lava?
Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.
