SUN The sun has ___________ % of matter in the solar system.
Explanation
The correct answer is 99.85%. This means that the sun contains 99.85% of the matter in the solar system. This indicates that the sun is by far the largest and most massive object in our solar system, containing the majority of the mass and gravitational pull.Rate this question:

MERCURY The sun shines ______________ times brighter on Mercury than the Earth.
Explanation
The sun shines 11 times brighter on Mercury than the Earth because Mercury is much closer to the sun than Earth. The intensity of sunlight decreases with distance, so being closer to the sun means that Mercury receives more sunlight and appears brighter.Rate this question:

VENUS Venus's atmosphere is made mostly of ____________________ _____________________ , which traps heat like a greenhouse.
Explanation
Venus's atmosphere is made mostly of carbon dioxide, which traps heat like a greenhouse. This phenomenon is known as the greenhouse effect. The high concentration of carbon dioxide in Venus's atmosphere creates a thick layer that prevents heat from escaping back into space, causing the planet to have extremely high temperatures.Rate this question:

MOON The moon orbits the Earth once every ________________________ days or so.
Explanation
The moon orbits the Earth once every 28 days or so. This is the average length of its lunar cycle, known as a synodic month. During this time, the moon completes a full cycle of phases, going from new moon to full moon and back again.Rate this question:

EARTH Earth has a _______________________ ______________________ that protects the life forms on its surface from storms of particles from the sun.
Explanation
The Earth has a magnetic field that acts as a protective barrier against storms of particles from the sun. This magnetic field is generated by the movement of molten iron in the Earth's outer core. It extends from the Earth's interior into space and helps to deflect and trap charged particles, preventing them from reaching the surface. This magnetic field is essential for the survival of life forms on Earth as it shields the planet from harmful solar radiation and solar wind.Rate this question:

VESTA Vesta, a large asteroid, may have had a ______________________ rock core at one time.
Explanation
Vesta, a large asteroid, may have had a liquid rock core at one time. This suggests that the asteroid was once molten, possibly due to the heat generated from its formation or from subsequent impacts. The presence of a liquid core could have influenced the geological processes and evolution of Vesta, including the formation of its surface features and the differentiation of its interior.Rate this question:

JUPITER Jupiter is the largest planet. With its many moons and huge magnetic field, it's almost like a mini ________________________ ________________________ .
Explanation
Jupiter is referred to as a mini solar system because it has many moons and a large magnetic field, similar to the characteristics of our solar system. Just like how our solar system consists of multiple planets and smaller celestial bodies orbiting around the sun, Jupiter has numerous moons orbiting around it. Additionally, its strong magnetic field resembles the sun's influence on the planets in our solar system. Therefore, Jupiter's resemblance to a mini solar system is due to its moons and magnetic field.Rate this question:

EUROPA Scientists would like to study below Europa's icy surface. They would like to examine the ___________________ _______________________ for signs of life.
Correct Answer(s)
liquid oceans
liquid oceanExplanation
Scientists would like to study below Europa's icy surface to examine the liquid oceans for signs of life. This is because liquid water is a key ingredient for life as we know it. The presence of liquid oceans on Europa suggests the possibility of habitable conditions and the potential for the existence of microbial life or other forms of life. By studying the liquid oceans, scientists hope to gather evidence of any signs of life that may exist on Europa.Rate this question:

CALLISTO Callisto has more __________________________ than any other object in the solar system.
Correct Answer(s)
cratersExplanation
Callisto has more craters than any other object in the solar system. This means that it has experienced more impacts from asteroids and other celestial bodies over its lifetime compared to other objects. The high number of craters suggests that Callisto's surface is very old and has not been significantly modified by geological processes.Rate this question:

TITAN Titan has rivers of liquid ___________________ (the compound in natural gas).
Correct Answer(s)
methaneExplanation
Titan, one of Saturn's moons, is known to have rivers of liquid methane. Methane is a compound found in natural gas and is commonly known as a greenhouse gas on Earth. On Titan, the extremely cold temperatures allow methane to exist in its liquid form, creating rivers and lakes. This discovery has provided valuable insights into the unique geology and potential for life on this moon.Rate this question:

URANUS Methane makes Uranus look _____________________ (color).
Correct Answer(s)
blueExplanation
Methane in the atmosphere of Uranus absorbs red light and reflects blue light, giving the planet its distinct blue color. This is due to a process called Rayleigh scattering, where shorter wavelengths of light (such as blue) are scattered more easily by the molecules in the atmosphere. As a result, the blue light is scattered in all directions, making Uranus appear blue to observers on Earth.Rate this question:

URANUS JOKES……VERY LAME, BUT MOST KIDS LOVE THEM. Just for fun…….not graded. Thanks to scientist, Ben Dover for his discovery, we can all look up at URANUS now.URANUS is four times the size of Earth, larger than originally believed.Scientists had originally thought URANUS was 1.7 billion miles from Earth. This is wrong. It's closer that you think!There are no incidents of moons associated with URANUS. pHEW!!! That was a close one.I didn't think URANUS was the one with a big red spot.Do you know what happens when you ride a bicycle on a different planet? I was hoping you'd know because I saw some skid marks around URANUS.When earth's rotation causes us to face URANUS, I can only hope I'm upwind.What are those rings around URANUS?News Flash: The massive black hole located dead center of URANUS seems to be pulling the two moons right in.Don't look now, but there are rings around URANUS.The top religious and scientific figures are debating whether URANUS is holy or not.URANUS makes earth seem small.URANUS and it's moons are always visible to the naked eye.This morning, NASA released a news statement saying there will never be a mission to URANUS. It is far to dangerous, due in part, to the crushing gravity of the black hole located in the heart of it and it's crappy terrain.Due to the poisonous gases that exist, Man can not survive anywhere near URANUS.New scientific studies reveal that there are not five moons on URANUS, but only two, very large moons.Although URANUS is very far from earth, due to its large size there is no surprise it took man so little time to find it.When I go to see URANUS, will it be bright? Remind me to bring my blinders anyway.

COMETS A comets tail is made of __________________ _________________ .
Correct Answer(s)
water vaporExplanation
A comet's tail is made of water vapor. When a comet gets closer to the sun, the heat causes the frozen water on the comet to turn into gas, creating a glowing tail. This tail is composed of water vapor, along with other gases and dust particles that are released from the comet's nucleus. As the comet moves through space, the solar wind pushes the tail away from the sun, creating the characteristic curved shape.Rate this question:
