the process of laying down sediment and a phase transition in matter

the idea that natural processes have operated in the same way throughout the past and present, and will continue to do so in the future.

A place where two tectonic plates move toward each other and collide

The theory that the crust is divided into large pieces called tectonic plates that slowly move on top of the mantle

a collection of fossils documenting the history of life on Earth.

The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates “float” and move on this layer

The process that formed and changed Earth from its beginning to the present

The boundary between two tectonic plates moving toward each other, resulting in volcanic activity when a denser oceanic plate subducts, or moves below, a continental plate or another oceanic plate

temperature, humidity, air pressure, wind speed, and air quality measurements

The process of determining an approximate computed age in archaeology and geology

divides up the history of the earth based on life-forms that have existed during specific times since the creation of the planet.

the process by which natural forces, like water or wind, wear away and transport materials like soil or rock

the idea that natural processes have operated in the same way throughout the past and present, and will continue to do so in the future.
