Not many people notice the ground they stand on for most of the day. It is something we take for granted but really deserves more than a second glance.
There is an entire branch of science that studies the ground below us called Geology. Geologists concern themselves with the composition, formations, patterns and processes of the Earth.
Like all branches of science, geology has several specialized terms pertaining to its study. This geology word search contains 30 geology glossary terms and is a great introduction for students.

These geology terms can be found in all directions: up, down, diagonally, forward, and backward. See how quickly you can find all 30 terms.

Conglomerate – A rock containing individual rock pieces cemented together
Crust – The outermost solid layer of the Earth
Crystal – A solid with a highly ordered microscopic structure arranged in a lattice extending in all directions
Earthquake – A shaking of the Earth’s surface from sudden disturbances in the lithosphere
Erosion – Destruction or displacement of solids by the actions of water, wind, ice, gravity or friction
Fault – A fracture in a volume of rock showing displacement as a result of forces affecting the volume of rock
Fossil – Any mineralized sample of a previously living organism
Gemstone – Any mineral crystal which can be cut and polished into jewelry
Geology – The science of the composition of the Earth and its processes over time
Igneous – A type of rock formed from the solidification of cooling magma
Inner Core – The innermost layer of the Earth consisting primarily of a solid mass of iron and nickel with a radius of approximately 1220 km (758 miles)
Lithosphere – Combination layer consisting of the crust and outer solid mantle
Loupe – A handheld optical device used to magnify rock samples. One of the two main tools of a field geologist.
Magma – liquified rock found under the lithosphere and occasionally extends into the lithosphere in volcanos and magma chambers
Mantle – Layer of liquified rock between the Earth’s crust and outer mantle
