Plate Tectonics

yes

Continental Drift Theory

proposes that continents were once joined together in a single landmass (Pangaea) and have since drifted apart over geological time.

Alfred Lothar Wegener

was a German polar researcher, geophysicist, and meteorologist who introduced the Continental Drift Theory.

Geological “fit“ Evidence

is the matching of large-scale geological features on different continents.

Fossil Evidence

refers to the discovery of similar fossils of plants and animals across continents, supporting the idea that they were once connected.

provides a record of how creatures evolved and how this process can be represented by a “tree of life,“ showing that all species are related to each other.

Lithosphere

is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Crust

made of various types of rocks and sediments.

Continental Crust

the thicker part of the Earth's crust that forms the continents, composed mainly of granitic rocks. (thicker and less dense)

Oceanic Crust

the thinner part of the Earth's crust that underlies the ocean basins, primarily made up of basaltic rocks. (thinner and more dense)

Plates

sections of the Earth's lithosphere that move and interact with one another.

Earthquake Distribution

the pattern of earthquakes around the world, often concentrated along plate boundaries/margins where tectonic activity occurs.
