Question | Answer |
geologist | scientist who study the forces that make and shape the planet Earth |
crust | the outermost solid layer of the earth |
mantle | is located between the core and the crust. It is a region of hot, slow flowing, solid rock |
core | extends from below the mantle to the center of the Earth. Believed to be made mostly of iron and some nickel. |
convection | is the movement of matter that results from differences in density caused by variations in temperatures |
convection currents | heating and cooling of a fluid, changes in its density, and gravitational pull |
lithosphere | The Outermost, rigid layer of Earth. Two parts. The crust and the rigid, upper part of the mantle. It is divided into pieces called tectonic plates. |
asthenosphere | is the layer of weak or soft mantle that is made of rock that flows slowly. Tectonic plates move on top of this layer. |
mesosphere | The strong, lower part of the mantle. Rock flows more slowly. |
outer core | is the liquid layer of the Earth's core. It lies beneath the mantle and surrounds the inner core. |
inner core | is solid, dense center of our planet that extends from the bottom of the outer core to the center of the Earth. |
