Earth Science Vocabulary Inexhaustible resource Resources that cannot be used completely. This includes Solar Energy, Ocean Tides, and Wind. Nonrenewable resource A resource that cannot be replaced in nature. This includes metals and minerals. Renewable resource Natural resources that can be renewed or replaced by nature. This includes food crops and water. Natural resource Resources that are used by humans. This includes minerals, water, fossil fuels, and food sources. Fossils The remains of any organism from the past Fossil Fuel A resource that comes from the body of dead organisms which lived millions of years ago. Sedimentary Rock Rocks formed as sediments are pushed together or cemented by the weight of the water and layers of sediment above it.

Superposition When items are stacked on top of one another, the layers on the bottom are older than the layer on top. Sequence An event that happens in a specific order Clues Hints of information that help someone Crust The outermost rocky layer of Earth Plate Tectonics Large plates that float on the mantle and make up the Earth’s crust Rock Cycle
