• Lithosphere is the solid part of the earth
• Hydrosphere is the total amount of water on a planet
• atmosphere is a layer or a set of layers of gasses surrounding a planet
• biosphere is the part of the world in which life can exist
• Igneous rocks formed from the cooling of magma and lava
• Sedimentary rocks are formed from pre-existing rocks or pieces of once living organisms
• igneous rocks - Rhyolite
• igneous rocks - granite
• igneous rocks - Basalt
• Sedimentary rocks - Limestone
• Sedimentary rocks - conglomerate
• Sedimentary rocks - dolomite
• Sedimentary rocks - shale
• Metamorphic rock formed through alteration of preexisting rocks
• metamorphic rocks - slate
• metamorphic rocks - marble
• metamorphic rocks - gneiss
• weathering - breakdown of rocks at the Earths surface
• Erosion geological process in which earthen materials are worn away and transported by natural forces such as wind and water
• erosion - weathering + transportation
• sediments - sand, gravel, mud, clay, etc.
• deposition - sedimentary rock formation from eroded material deposited on land or sea floor
• sediments - solid particles that have been broken down, carried along, and then deposited somewhere else.
• lithification - compaction and cementation of sediments to form solid rock
