Gravity & Space
The strength of the force of gravity b/w objects depends on these TWO things
What is mass and distance?
Number of waves that pass a given point in a specific amount of time.
What is frequency?
Part of spectrum used to see bones in the body.
What is an x-ray?
The 4 layers of Earth.
What are the crust, mantle, outer core and inner core?
One piece of evidence that continents were once connected.
What is fit like a puzzle, same fossils on diff continents, same rocks/landforms on diff continents?
Exact place where an earthquake occurs (underground).
What is the focus?
These tides occur when the Sun, Earth, and Moon are in a STRAIGHT line (full or new moon).
What is a Spring Tide?
Waves that travel parallel to the medium.
What are longitudinal?
Part of the spectrum that we can see.
What is visible light?
Upper part of the mantle where extreme heat and pressure cause rocks to "flow"
What is asthenosphere?
Seafloor spreading is caused by this type of plate boundary.
What is divergent?
First seismic waves to arrive, they are the fastest and travel through all states of matter.
What are P-waves (primary waves)?
Name AND type of galaxy we live in.
What is the Milky Way, spiral galaxy?
Waves that require a MEdium to travel through.
What are MEchanical waves?
Part of the spectrum with the highest frequency.
What are gamma rays?
Solid outer part of Earth, includes the brittle upper part of crust and mantle
What is the lithosphere?
Type of plate boundary when two plates slide past each other.
Seismic waves that are the most destructive, are the last to arrive and are the slowest.
What are surface/land waves? (L-waves okay)
The stretching of light as it is moving away from the observer.
Signals composed of only 0 and 1, are used in cell phones, and can transmit large amounts of data.
What is/are digital?
Part of spectrum with the lowest frequency and the longest wavelength.
What are radio waves?
Name of the currents found in the asthenosphere.
What are convection currents?
Type of plate boundary when plates collide, forming mountains.
What is convergent?
What is the epicenter?
Theory that proposed that an explosion created the universe.
What is the Big Bang Theory?
Type of interference when two waves line up to form a smaller wave.
What is destructive (interference)?
Used in thermal imaging, remote controls, and meteorology.
What is infrared?
Name one of the metals found in the core.
What is iron? or What is nickel?
When oceanic and continental plates meet, this one subducts.
What is oceanic? (It's denser)
Another word for the strength of an earthquake.
What is magnitude?
