1.

I have the greatest range of temperatures of any planet in the solar system. Very hot days and very cold nights. I have a low surface gravity, a thin atmosphere, and lots of craters.which planet am I?

a)

Mercury

b)

Mars

c)

Venus

d)

Earth

2.

I am an planet that has the largest volcano in the solar system called Olympus Mons. My atmosphere is very thin and my surface is cold. I have polar ice caps of frozen water and carbon dioxide. I also have seasons because I am tilted on my axis as I revolve around the sun. Which planet am I?

a)

Mercury

b)

Mars

c)

Venus

d)

Earth

3.

I am a planet that is about the same as Earth. I have a thick atmosphere of mostly carbon dioxide this causes my surface temperature to be the hottest of any other planet at 464 degrees C. I also have clouds of sulfuric acid and lots of active volcanoes. My pressure is 90 times that of Earth and I have retrograde rotation (backwards). Which planet am I?

a)

Earth

b)

venus

c)

Mars

d)

Mercury

4.

I am the only planet in are solar system known to have liquid water and life forms. I have seasons because I am tilted on my axis as I revolve around the sun. My atmosphere protects the surface from the sun's radiation and creates a constant range of temperatures. Which planet am I?

a)

Earth

b)

Venus

c)

Mars

d)

Mercury

5.

I am a planet who was discovered by mathematical prediction. I have visible clouds in my atmosphere which consist of hydrogen, helium, and methane. I have many storms because of the difference in my core temperature and my cloud temperature. Because of the temperature differences my wind speed often reach 2000 km/hour. Which planet am I?

a)

Neptune

b)

Uranus

c)

Saturn

d)

Jupiter

6.

I am a frozen ball of rock and ice. I have a very thin atmosphere of nitrogen, methane and carbon monoxide gases. My surface is 98% frozen nitrogen, some methane and carbon monoxide. I am one of the furthest from the sun and have been demoted to dwarf status. Which planet am I?

a)

Neptune

b)

Kuiper Belt

c)

Pluto

d)

Ceres

7.

I am the largest planet in the solar system. My gravitational force is 3 times that of Earth and my pressure is 30 million times greater than the Earth’s surface. I am known for my red spot which is a storm. I am made of mostly hydrogen and helium. Which planet am I?

a)

Saturn

b)

Neptune

c)

Jupiter

d)

Uranus

8.

I am made of mostly hydrogen and helium with methane, ammonia, and ethane in my upper atmosphere. My density is .70 which is less than the density of water. I have the most rings of any other planet in the solar system. One of my major moons is called Titan. Which planet am I?

a)

Jupiter

b)

Saturn

c)

Neptune

d)

Uranus

9.

I am the smallest of the outer planets with a bluish-green color. My atmosphere is primarily hydrogen and methane gas. I have a top to bottom rotation unlike other planets that rotate side to side. Which planet am I?

a)

Jupter

b)

Neptune

c)

Uranus

d)

Saturn

10.

I am a chunk of rock or dust in space. When I enter the Earth’s atmosphere I am heated by friction until I glow. Many of my kind burn up before we reach the Earth’s surface. What am I called when I am burning in the atmosphere?

a)

Meteor

b)

Meteorite

c)

Asteroid

d)

Comet

11.

I have a tremendous amount of gravitational pull, the strongest of any other object in our solar system. In my core hydrogen is fused together to make helium. This creates heat and light energy that I share with the planets in my solar system. I am known as a middle aged yellow dwarf which is a type of star. Which space object am I?

a)

Andromeda

b)

Betelgeuse

c)

Sun

d)

Jupiter

12.

Luna is my name and I am a natural satellite. I have many craters and a very low gravitational force. I am the reason for tides and have many phases. Which space object am I?

a)

Earth's moon

b)

Saturn's moon

c)

Venus' moon

d)

asteroid

13.

I am a rocky fragment left over from the formation of the solar system. Most of my kind congregates in a belt between Mars and Jupiter. Some are very small and others are as large as 250 km. I have been known to leave huge craters like the one in Mexico 65 million years ago. Which space object am I?

a)

Asteroid

b)

Meteroid

c)

moon

d)

Meteor

14.

I am a chunk of rock or dust in space. When I enter the Earth’s atmosphere I am heated by the friction until I glow. Many of my kind burn up before we reach the Earth’s surface. What am I called when I impact the Earth’s surface?

a)

Falling stars

b)

Meteorite

c)

Meteoroid

d)

Comet

15.

This space object can be either terrestrial or gaseous, they may have rings and some unique surface characteristics, they revolve around the sun and rotate on their axis. What space object am I?

a)

Moons

b)

Planets

c)

Comets

a)

Moons

b)

Planets

c)

Comets

d)

Asteroids

17.

These space objects are rocky bodies that orbit in a region in the solar system between Mars and Jupiter. They vary in size and shape their movement is based on their revolution around the sun.

a)

Meteoroids

b)

Asteroids

c)

Meteors

Comets

18.

I have a main body or head of frozen water, methane, ammonia, and dust. I have a tail that emerges as this object gets closer to the sun during its long, narrow elliptical orbit.
