Evolutionary Theories
Evolution – the process of change over time
Tectonic Plates – giant chunks of land or ocean floor in which the lithosphere
is broken up into
Theory of Plate Tectonics – a theory that states that Earth’s lithosphere, or
land, is broken into large sections called tectonic plates that move and change
position over time (aka continental drift)
Fault – a break or crack in Earth’s surface along which movement occurs
Convergent Boundary – the location where two tectonic plates push together
where either both plates push up or one is pushed underneath the other plate
Divergent Boundary – the location where two tectonic plates pull apart
Transform Boundary – the location where two tectonic plates slide past each
other
Lithosphere – the uppermost layers of Earth made up of solid rock where the
top layer is called the crust
Asthenosphere – the soft layer of the mantle made up of semisolid rock that
flows slowly
Weathering – process in which rocks are broken down into smaller pieces
through the action of wind, water, roots, and animals
Erosion – a process by which weathered rock is picked up and moved to new
places (aka deposition)
Sediment – weathered rock and other materials deposited by water, wind, or
ice that can form into sedimentary rock when compacted.
