Light, Electromagnetic, Action!
The non-visible light with highest frequency and most energy.
What is Ultraviolet light/radiation?
The process that occurs in stars by which two atoms are combined to produce a new element and release electromagnetic radiation.
The main attractive force that pulls all objects towards each other.
What is gravity?
The type of boundary where two tectonic plates move directly away from each other.
What is divergent?
The three main categories of rocks.
What are igneous, metamorphic, and sedimentary?
The non-visible light with the lowest frequency and largest wavelength.
What is microwave radiation?
This property of stars determines the type of life-cycle the star will follow (what it will become, how it will collapse).
What is the mass?
The shape of planetary orbit when its eccentricity is 0.
What is a perfect circle?
The type of plate boundary where two plates collide directly into one another.
What is convergent?
The process by which rocks are broken down into sediments.
What is weathering?
The radiation pattern from stars that provides us with evidence of what elements those stars are made of.
What are emission/absorption spectra?
The stars that are so massive, they can create heavier elements in their core.
What are red giants?
The time it takes for a planet to complete one trip around the Sun.
The type of boundary where two tectonic plates slide past each other.
What is transform?
From outermost to innermost, the predicted phase of matter of each layer of the Earth.
The natural phenomena where objects moving away from the observer appear to emit longer wavelengths of light.
What is Red Shift?
The amount of time it takes for 50% of the unstable parent isotope to decay into the daughter element.
What is radioactive half-life?
The property of a planet that helps determines how long the period of revolution is and what phase of water we expect to find on it.
What is the distance from the Sun/star?
The property of the crust that increases symmetrically (on both sides) as you move away from mid ocean ridges.
What is the age of the crust?
The type of seismic wave that can pass through solids only.
What are S or shear waves?
This discovery of similar energies being measured in all directions in the universe is evidence that supports the Big Bang Theory.
The name of the period of time around 4.1 billion years ago (as supported by radioactive dating) when lots of asteroids where crashing into Earth and other planets.
The late heavy bombardment (LHB)?
This describes what happens to the speed of an asteroid as it gets closer to the Sun (or to another much larger mass).
What is gets faster/increases?
The movement of land that changes the surface of the Earth, leading to the creation and destruction of oceans and ecosystems, resulting in changes to ancient life.
What is continental drift?
The process by which hotter/less dense materials rise and colder/more dense materials sink that is claimed to be responsible for plate movements.
What is convection or convection currents?
