In this cycle matter is recycled over and over
The Rock cycle
This force pulls on Earth's crust, stretching the rock to make it thinner.
Tension
This sinking of oceanic crust into the mantle when it meets continental crust is called subduction and occurs at these locations
Ocean trenches
This is a streak of light made when an object burns up as it enters Earth's atmosphere
a meteor
According to ancient astronomers this was the center of the solar system
Earth
Mid-ocean ridges and rift valleys are caused by this type of plate interaction.
Divergent plate boundaries
Rocks are classified by these three characteristics
texture, color and mineral composition
Cooling magma creates this type of rock
Igneous
This is the layer of Earth's interior that transfers thermal energy through convection currents.
Mantle
Larger stars produce more of this
heat and energy
These moon phases occur when the line between the Earth and Sun is at a right angle to the line between Earth and the Moon.
first and third quarter moon
Oceanic-continental converging plate interactions create these.
Continental volcanic arches
This is the thinnest layer of Earth
Crust
All tectonic plate interactions excepting continental continental convergent and transform plate boundaries create these.
Volcanoes
This is what makes the stars appear to move across the night sky.
The rotation of the Earth
During one trip around the Sun the Earth travels about this far
150,000,000 kilometers
A solar eclipse will always be accompanied by this type of tide.
Spring tide
Continental continental converging plate boundary interactions create these
Mountains
In convection currents materials rise because of this
It is heated by the Earth's core.
When the Earth tilt points the northern hemisphere towards the sun it will be this season in the North
summer
Plant and animal fossils of the same species discovered on separate land masses is used as evidence to support this theory.
Continental Drift Theory
Gravity pull gasses and dust from a nebula cloud to create the beginnings of a star which is called this
protostar
This type of electromagnetic energy has longer wavelength that visible light but has shorter wavelength that microwaves
Infrared light
As mantle material is heated from the core the rock melts, becomes less dense then the surrounding material and does this.
rises
In this process rocks are changed from one type of rock into another type of rock by heat and pressure
Metamorphism
These waves travel outward in all direction from where the ground breaks in an earthquake
Seismic waves
This causes the constellations to only be visible during certain times of the year.
The Earths revolution
This attracts the moon towards the Earth.
Gravity
Because the Earth is tilted as it rotates on its axis while orbiting the Sun these occur
Seasons
This occurs in the middle of a tectonic plate and creates Island volcanic chains in the oceanic crust and large calderas on continental crust .
Mantle plumes
New crust forming as magma rises through cracks in the Earth called mid ocean ridges with older rock farther away from the ridge and newer rock closer to the ridge is and example of this
Seafloor spreading
These tides created by the alignment of the Moon and Sun with the Earth provide the largest waves during high tide
Spring tides
This occurs when the position of the Moon is perpendicular to the positions of the Earth and Sun
Neap tide
These are not used to measure distance in our solar system because it is too small.
light years
In this Model of the solar system the Sun is the center
Heliocentric Model
Oceanic-oceanic diverging plate boundaries create these structures.
Mid-ocean ridges
Pressure creates these two types of rocks
Metamorphic and Sedimentary
The gravitational interactions between the Earth the moon and the Sun combine to create these phenomena
Tides
This is what keeps the Moon in motion as it orbits the Earth.
Inertia
This is what becomes of a massive start that dies and has its gravity pull surrounding material into a smaller and smaller space
Black Hole
These are the remains of the material that formed the early solar system and are thought to be similar to Earth's interior.
meteorites
The San Andrea's Faultline is this type of plate boundary
Transform Plate Boundary
