Name the three main types of rocks and briefly describe each.
The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma or lava. Sedimentary rocks are formed by the accumulation and compaction of sediments. Metamorphic rocks are formed from existing rocks that are changed by heat, pressure, or chemical processes.

What is the principle of uniformitarianism?
The principle of uniformitarianism is the concept that the geological processes observed in the present have operated in the same way throughout Earths history.

How are minerals different from rocks?
Minerals are naturally occurring, inorganic solids with a specific chemical composition and a crystalline structure. Rocks are aggregates of one or more minerals or mineraloids.
input text value
What is the Mohs scale of hardness?
The Mohs scale of hardness is a qualitative ordinal scale that characterizes the scratch resistance of various minerals through the ability of harder materials to scratch softer ones.
input text value
Explain the rock cycle.
The rock cycle is a continuous process by which rocks are created, altered, destroyed, and reformed by geological processes, involving igneous, sedimentary, and metamorphic rocks.

What is plate tectonics?
Plate tectonics is the theory that Earths outer shell is divided into several plates that glide over the mantle, leading to seismic activity, continental drift, and the formation of mountains and oceanic trenches.
input text value
Describe the difference between continental drift and plate tectonics.
Continental drift is the hypothesis that continents move across Earths surface over geological time, while plate tectonics is the theory that explains how the movement of tectonic plates causes continents to drift.
