SparkNotes: Venus: Review Test

In what way are Earth and Venus similar?

(A) They have similar mass and size.

(B) They revolve around the Sun at the same distance.

(C) They both have a magnetic field.

What is a 'greenhouse' gas?

(A) A gas found in greenhouses.

(B) A gas that traps visible light and lets infrared heat radiation through.

(C) A gas that traps infrared heat radiation and lets visible light through

What did Galileo find by watching Venus with a telescope?

(A) He found that Venus was always in a crescent phase, and therefore the Sun is at the center of the solar system.

(B) That Venus appeared to have ice on its surface.

(C) That Venus displayed all phases, like the Moon. Therefore the Sun is at the center of the solar system.

The rotation of Venus around its axis is

(A) relatively fast, about 5 Earth days long.

(B) slow, taking about 243 days, in the same direction as the Earth's.

(C) slow, taking about 243 days, and retrograde.

The pressure of Venus' atmosphere is

(A) lower than the Earth's.

(B) high, like the pressure of ocean water at 100 m depth.

(C) high, like the pressure of ocean water at 1 km depth.

The pressure of Venus' atmosphere is correlated to

(A) the presence or absence of water oceans.

(B) plate tectonics

(C) the absence of plant life.

In what form do we find water on Venus?

(A) Only large quantities of vapor.

(B) Liquid water and vapor.

(C) Negligible amounts of water.

In what way did scientists map the surface of Venus?

(A) By taking images with an infrared camera aboard orbiting probes.

(B) By taking images with telescopes on Earth.

(C) By using radar techniques.

The clouds on Venus are made of

(A) water

(B) methane

(C) sulphuric acid

The carbon dioxide in Venus' atmosphere was:

(A) generated by primordial animal life on the planet

(B) always present, and further replenished by volcanoes

(C) the result of a collision with an asteroid

Venus' surface is made of:

(A) sedimentary rocks.

(B) volcanic rocks, coming from a few major volcanoes.

(C) volcanic rocks, coming from widespread eruptions.

How was the surface of Venus formed?

(A) by a gradual process, like Earth's plate tectonics.

(B) by a gradual process, by the action of volcanoes.

(C) by a process taking place relatively suddenly.

What are hot spots?

(A) regions in Venus' atmosphere.

(B) volcanic regions on Venus' surface.

(C) hot molten regions deep in Venus' mantle, giving rise to localized volcanism.

What do scientists think about Venus' interior, in relation to Earth's?

(A) Venus has an interior very different from Earth's.

(B) Venus' interior is similar in composition to Earth's, but solid.

(C) They should be very similar.

In the study of Venus, what were meteoric craters used to measure?

(A) Venus' magnetism.

(B) Venus' age.

(C) the age of Venus' crust.
