What is the formula for Gradient?
Gradient=change infield value over time
What are the two ingredients needed to make a star?
Mass (Gas and Dust) and gravity (pulls mass in to create nuclear fusion)
What kind of Galaxy is the milky way?
Spiral
According to the ESRT, what is the most dense object in the Solar System?
Earth; density is 5.5 g/cm^3
What is the formula for Density?
Density = Mass/volume

When stars burn up all their hydrogen fuel and before they become a white dwarf, neutron star, or black hole, stars turn into what kind of star?
Giant or super red giant
How many rotations does Jupiter does make in 24 hours?
About 2.4 rotations in a day on earth
Which planet is farthest from the Sun?
Neptune
What is the formula for rate of change?
Rate of Change = change in value/time
Points A and B are points on a river. Point A is 600m above sea level and point B is 1,000m above sea level. What is the gradient between Points A and B and which way does the river flow if the points are 1 km apart?
Gradient = 400m/km
B to A
What color is the star Sirius?
White
What is the difference between an asteroid, comet and and meteoroid?
Asteroids: Rocky metallic from asteroid belt
Comets: Mostly Ice and some dust from the Kuiper belt and Oort Cloud
Meteoroid: Rocky debris that sometimes falls into earths atmosphere becoming a meteor
Which planet's rotation is fastest?
Jupiter
What is the density of an object that is 350g and occupies a volume of 50 mL?
7 g/mL
Define contour lines, index lines, and contour interval.
contour lines: measure elevation
index lines: thick line that has elevation labeled
contour interval: the difference in elevation between contour lines
Draw the HR diagram and list the stages of a life cycle of the sun on it.

What are the two pieces of evidence for the Big Bang Theory?
Cosmic Background Radiation and Red Shifting Galaxies
What is the difference between revolution and rotation?
Rotation is spinning on an axis
Revolution is orbiting around another object.
At the start of the race the temperature was 60 degrees and the finish line, 3 miles away, the temperature is 72 degrees. What was the temperature gradient from the start line to the finish line?
4 degrees/mile
Explain at least three differences between latitude and longitude
Parallel circles vs semi circles
Runs east west vs runs north south
Measures north south vs measures east west
Measure first vs measure second
Equator and parallels vs Prime Meriden and meridians
Up to 90 degrees vs 180 degrees
Explain three ways how Procyon B is different from Betelgeuse.
Procyon B is hotter, less massive, less luminous and is in the final stage of being a star since it is a white dwarf.
Betelgeuse is cooler, massive, extremely luminous and in the second stage of being a star since it is a red super giant. It will become a black hole.
Explain the doppler effect.
As a light source moves away from an observer light waves appear longer in wavelength and hence appear redder. As a light source moves closer the wavelengths appear shorter and the light appears bluer.
Explain the difference between Terrestrial and Jovian Planets
Terrestrial are smaller, rocky, and dense
Jovian are bigger, gaseous and less dense
A rectangle is 5cm by 2cm by 10cm and has a density of 10 g/cm^3. What is the rectangle mass? Show your work.
1000g
