Evolutionary History
The process by which organisms better adapted to their environment tend to survive and reproduce, passing on favorable traits
What is natural selection?
At these plate boundaries, plates move apart causing magma from the mantle to the Earth's surface to create mid ocean ridges.
What are divergent boundaries?
Earthquakes, volcanoes, and mountains all exist near what geologic feature.
What are plate boundaries?
A natural event that changes the surface of the Earth, such as erosion, weathering, and plate tectonics.
What are geoscience processes?
The giant supercontinent that existed about 300 million years ago.
What is Pangea?
The collection of all known fossils and their placement in rock formations, providing evidence of the history of life on Earth.
What is a fossil record?
At these plate boundaries, plates move towards each other creating mountains and sea floor trenches.
What are convergent boundaries?
The line of earthquakes volcanic activity that occurs around the pacific coast.
What is the ring of fire?
The breaking down of rock by wind, water, or ice.
What is weathering?
The theory of continental drift suggests that the continents were once connected as one supercontinent but gradually drifted apart due to ___________________.
What is plate tectonic movement?
This law states than in undisturbed sedimentary rock, the oldest layers are at the bottom of the rock strata (layer) and fossils located in deeper rock strata are older than fossils located closer to the Earth's surface.
What is the Law of Superposition?
At these plate boundaries, these plates slide past each other, creating earthquakes.
What is a transform plate boundary?
A fast, small-scale process of transform boundaries.
What is an earthquake?
The MOVEMENT of smaller broken-down rocks from one place to another.
What is erosion?
Evidence Alfred Wegener used evidence that showed identical species were found on continents now separated by oceans.
What are matching fossils?
Similarities in early embryological development and anatomy (body structures) provide evidence of ___________ and evolution.
What is common ancestry?
This process creates new crust at mid-ocean ridges of a divergent boundary.
What is seafloor spreading?
A slow, large-scale process at convergent boundaries.
What is mountain building?
The process where sediment settles and building up new landforms as a result of erosion.
What is deposition?
The coastlines of continents, such as South America and Africa, fit together like a ________ supports the theory of continental drift.
What is a puzzle?
These structures of organisms that look similar, like a bat wing and a human arm, show that they evolved from a common ancestor.
What are homologous structures?
(DAILY DOUBLE!) – When a denser oceanic plate slides beneath a less dense plate into the mantle, this occurs, often forming trenches and volcanoes. (DAILY DOUBLE!)
What is subduction?
This process causes the seafloor to be recycled as one plate sinks beneath another at convergent boundaries.
What is subduction?
Two scales used to measure geoscience processes.
What are temporal (time) and spatial (space)?
DAILY DOUBLE! The heating, cooling, and rising of material in the mantle that drives the movement of the tectonic plates in the lithosphere. DAILY DOUBLE!
What are convection currents?
