Event that created Hydrogen and Helium atoms.
The big bang
vibrations created when rock breaks and releases energy.
Seismic waves
Type of volcano formed near a subduction zone with an explosive eruption.
Stratovolcano
Type of boundary where new sea floor is created.
Divergent
Course of a river where the most erosion takes place.
Upper Course
rocky planets found closer to the sun
Terrestrial
Earth's layer that is made of solid rock
Crust/Lithosphere
Convergent boundaries
As the distance from the mid-ocean ridge increases, the age of seafloor ______________.
increases
Rocks formed when existing rocks are exposed to heat and pressure.
Metamorphic
The time it takes for half of the nuclei for a radioactive isotope to decay.
Half-Life
The thickest layer of our Earth's interior.
The Mantle
Feature that creates volcanoes in the Hawaiian Islands.
Hot Spot
Process in the mantle that causes the location of continents to change over time.
Convection currents
Rocks formed when molten lava from a volcano cools down and solidifies
igneous
Where most of the mass of our solar system is contained.
The sun
Seismic wave that does NOT travel through liquid.
S-Waves
Plate boundary characterized by plates grinding past eachother.
Transform boundary
Elongated depression that forms when tectonic plates move apart
rift valley
Type of boundary that is responsible for the uplifting that forms mountains
Convergent boundaries
Explosion that happens with a high mass star and creates the elements heavier than iron (Fe).
supernova
Layer of Earth's interior where the hypocenter of earthquakes are found
Lithosphere/Crust
Rock outcrops that have very similar mineral patterns, chemical composition and age, but found separated along a fault.
Geologic markers
Type of map that shows the shape of the ocean floor
Bathymetric map
Type of delta that looks like a birds foot.
River dominant delta
