DOUBLE Earth/Moon/Sun JEOPARDY!
100
The phenomenon that that describes the fact that the Moon rotates on its axis every 27.3 days as well as orbits around Earth every 27.3 days. It is the result of Earth's gravity.
What is the Moon's synchronous rotation?
100
The sunrise or sunset line on the Moon. This is the best place to observe Moon features.
What is the terminator?
100
This is a non-contact force that acts on objects. If two objects are placed in space, they will be drawn towards each other by this force. The greater the mass of the object, the stronger the force.
What is gravity?
100
These are like giant magnets on the photosphere where magnetic fields cause the plasma to slow and cool.
What are sunspots?
100
This is a non-contact force that acts on objects. If two objects are placed in space, they will be drawn towards each other by this force.
What is gravity?
200
The environmental condition that results in a significant range in surface temperature on the Moon (from -150˚C in at night to 120˚C during the day).
What is the lack of an atmosphere?
200
The powdery material that covers the surface of the Moon.
What is regolith?
200
Earth's rotational axis is tilted 23.5 degrees with respect to this path.
What is Earth's plane of orbit around the Sun (revolution around the Sun)?
200
In this process, the nuclei of atoms join together to form a larger nucleus under intense temperature and pressure.
What is nuclear fusion?
200
This is a small, orbiting body made up of dust, ice, and frozen gases. The solid center of this is its nucleus, and like all objects in the solar system it orbits the sun.
What is a comet?
300
The full Moon nearest the time of the autumnal equinox.
What is a harvest Moon?
300
This theory attempts to explain the origin of the Moon. It states that the Moon formed from the collision of a planet-size body with the Earth. As a result of the collision, material ended up in Earth's atmosphere and eventually collected into the Moon.
What is the impact-ejection hypothesis?
300
This can only occur when: 1. The phase of the Moon is full. 2. The Moon is farther away from the Earth than the length of its umbra.
What is an annular eclipse?
300
This is the innermost part of the sun where it's energy is generated.
What is a the Sun's core?
300
In this process, the nuclei of atoms fuse together to form a larger nucleus.
What is nuclear fusion?
400
Dark areas on the Moon that appear as if they are bodies of water, but are actually dry lava beds made of basalt, a type of igneous rock.
What are maria?
400
The points at which the Moon's orbit crosses the the plane of Earth's orbit.
What are nodes?
400
This is the innermost layer of the sun where nuclear fusion occurs.
What is the Sun's core?
400
This is the last stage of a stars life.
What is a black dwarf star?
400
This is a large rotating cloud of dust and hydrogen gas.
What is a nebula?
500
This phenomenon can only occur when the Earth, Sun, and Moon are in syzygy during the new Moon.
What is a lunar eclipse?
500
Three conditions that are a result of the lack of Moon atmosphere.
What is silence, significant range in surface temperature, and absence of weathering and erosion?
500
The amount of Sun's energy that falls per second on Earth's outer atmosphere (1400 watts/m2).
What is the solar constant?
500
This is the term used to describe a star that has stabalized.
What is a main-sequence star?
500
This planet takes 163 Earth years (365 days = 1 Earth year) to orbit around the sun once!
