core
the central part of the earth below the mantle
crust
the thin and solid outermost layer of the earth above the mantle
decision making model
a conceptual model that provides a systematic process for making decisions
erosion
a process in which the materials of earth's surface are loosened, dissolved, or worn away and transported from one place to another by a natural agent, such as wind, water, ice, or gravity
geosphere
the mostly solid, rocky part of earth; extends from the center of the core to the surface of the crust
lithosphere
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
mantle
in earth science, the layer of rock between the earth's crust and core
