A large cloud of gas and dust where stars and planets can form.
What is a nebula?
The force of attraction between masses
What is gravity?
This movement gives us a 24 hour day and night cycle.
The light from the moon comes from this.
What is the reflection of the sun's light?
The layer of the sun where heat is generated through fusion.
What is the core?
These planets formed through the accretion of less dense, lighter material in the cooler zone of our solar system.
What are Jovian planets?
The spinning of an object around its axis.
What is rotation?
The movement of Earth around the sun.
What is revolution?
The moon cycle repeats after this many days.
What is 29.5 days?
Taking 2 or more atoms and combining them into 1.
What is fusion?
These planets formed through the accretion of rocky dense materials.
What are terrestrial planets?
the movement of an object around another body along an orbit.
What is revolution?
This line of latitude receives consistently direct rays of sunlight causing warm temperatures year round.
What is the equator?
During this moon phase the sun, moon, and earth are in a straight line with the moon positioned between the sun and earth.
What is a new moon?
This element is what undergoes fusion inside the sun.
What is hydrogen?
The Sun ignited when internal pressure and temperature became high enough for this process.
What is fusion?
The center of mass between two orbiting objects.
What is the barycenter?
The combination of the revolution of Earth and this answer cause alternating seasons.
What is the axial tilt?
During this tide the moon phase could be full or new.
What is spring tide?
This type of heat transfer occurs in the radiative zone of the sun.
What is radiation?
These two elements are what generally make up stars and Jovian planets.
What are hydrogen and helium?
The laws that state all orbits move in ellipses, that planets sweep out equal areas in equal times, and that planets orbital period is directly proportional to their distance from the star.
What are Kepler's laws?
The Earth is tilted at this angle.
What is 23.4 degrees?
During this tide their is either a first quarter or third quarter moon.
What is a neap tide?
This type of radiation has the smallest wavelength and the highest frequency of the electromagnetic spectrum.
What are gamma rays?
