6th Grade Final Review

How do the Sun, planets, moons, meteors, asteroids, and comets move in relation to other celestial bodies?

• all orbit, made up of elements, have mass,, originate from one source, and

• They all apply a push force on one another

• They are all stationary

• They only have massClear selection

Why is it appropriate to describe the Sun and its orbiting celestial bodies as a system? View options

• Like any system, everything is in order and repeats itself

• Like any system, everything is in disorder and random

• Like a few systems, all are found in the center

• Like any system, all travel in an elliptical path

How do masses, orbital paths, and movement of the inner planets compare to the outer planets of our solar system?

• The inner planets have a stronger force and speed than outer planets

• inner planets move slower than outer planets

• outer planets are all larger in mass

• all planets orbit the largest planet, Jupiter

How is the force of gravity different from magnetic force?

• Gravity has matter/mass; electromagnetic force acts on metals only.

• Gravity has electromagnetic force/magnetism has matter as a force

• Both repel objects.

• All are correct

What evidence do we have that gravity exists in space? View options

• An asteroid randomly tumbles through space

• The electromagnetic field lines that are measured on planets

• The light speed that travels through space

• The planets orbit around the sun because of gravity.

What essential needs of humans are needed in future space exploration?

• water only

• water food shelter only

• Only gravity, travel time, and distance from solar star

• water, atmosphere, food, shelter, gravity, distance from solar star

How might future space exploration benefit us?

• to understand the universe/our Creator better/ to backup of life on Earth

• To defy God

• To have more scientists

• To gain knowledge and power

space rock bigger than a meteoroid but smaller than a planet/usually orbits Mars & Jupiter

• Mars

• Jupiter

• Asteroid

• Meteoroid

Dense atmosphere, 67 moons, gas surface, rings of dust, largest planet in our system, and 5th planet from Sun

• Mars

• Jupiter

• Asteroid

• Meteoroid

Cold planet with thin atmosphere, 2 moons, 4th planet from the Sun

• Mars

• Venus

• Jupiter

• Asteroid
