Solar System
These rocky planets are located close to the sun.
terrestrial planets
The shape of a planets' orbit is described as this.
ellipse
The sun produces energy by combining hydrogen into helium in this process.
nuclear fusion
The supercontinent that once included all modern continents.
Pangea
The first seismic waves arrive at a seismograph.
P-waves
This theory explains how the solar system formed from a cloud of gas and dust?
Nebular Theory
Kepler's 3rd Law states that the square of the orbital period is proportional to the ________________ of the orbital radius.
cube
Energy moves by convection in this layer of the sun.
convection zone
Tectonic plates move due to convection currents in this part of Earth.
mantle / athesnosphere
The point on Earth's surface directly above an earthquakes origin.
epicenter
According to Kepler's 2nd Law, planets move faster when they are __________.
This orbital property describes how circular or elliptical an orbit is.
eccentricity
Shorter wavelengths of light have ________ energy.
more
A boundary where plates move apart and form rift valleys.
divergent boundary
Three seismograph stations are needed to do this.
triangulate the epicenter
The shared center of mass that Earth and the moon orbit around.
Barycenter
A satellite closer to the Earth moves __ than one farther away.
faster
Correct order from the lowest to the highest energy in the EM spectrum: microwave - radio - visible -ultraviolet - gamma - infrared - x-ray
radio -> microwave -> infrared -> visible -> ultraviolet -> xray -> gamma
This plate is subducting beneath South America to form the Andes Mountains.
Nazca Plate
Most volcanoes are found at these locations.
convergent boundaries, divergent boundaries, and hot spots
These tides occur during the new and full moons and have the greatest tidal range.
Spring Tides
This force caused the solar nebula to collapse and form the sun.
gravity
Stars with more hydrogen will produce energy for a __________ time.
longer
The original energy source driving plate tectonics.
radioactive decay in Earth's interior
