Astronomy Quiz # 1

Natural satellites are always spherical due to the gravitational force they exert.

• TRUE

• FALSE

Answer explanation

Some natural satellites are captured asteroids; hence, they don't have the ability to shape themselves to become spherical satellites.

Which of the following statements describes the formation of the Solar System?

• Dust particles are repelled as more mass forms at the central region.

• Icy seeds contain water, which formed terrestrial planets such as Earth.

• The temperature of the seeds inversely changes based on their distance.

• Non-planetary bodies formed early in the Solar System.

Answer explanation

The farther the particles are from the center, the lower the temperatures they have.

Jupiter holds most of the mass in the Solar System.

• TRUE

• FALSE

Answer explanation

Despite being the largest planet, Jupiter does not have most of the Solar System's mass -- the Sun holds this title.

What type of tide represent extreme changes in water levels?

• Neap

• High

• Ebb

• Spring

Answer explanation

During Spring Tide, the gravitational force of the moon compounds with the gravitational force of the sun, creating the highest high tides and lowest low tides.

Gaseous planets have more moons than terrestrial planets to compensate for a lack of surface for landing expeditions.

• FALSE

• TRUE

Answer explanation

Gaseous planets have more moons than terrestrial planets because they exert stronger gravitational force -- this allows them to capture satellites and have their own prograde moons.

The following are correctly matched, except:

• Meteor - Atmosphere

• Shooting Star - Surface

• Meteoroid - Space

• Meteortite - Surface

Answer explanation

Shooting star is another name for meteors!

Artificial satellites can become natural satellites when they are captured by large objects such as planets.

• FALSE

• TRUE

Answer explanation

Artificial satellites are defined as small objects created artificially (by a person) and revolves around a large body.

Which of the following characteristics set comets apart from asteroids?

• Comets are large chunks of rock hurtling across the Solar System.

• Comets can be classified as planetoids or dwarf planets.

• Comets contain ice that can melt to form its tail.

• Comets are often misidentified as meteorites.

Based on our class activity, the following can affect satellite communications except:

• Distance

• Infrastructures

• Signal Quality

• Device Used

Answer explanation

Devices that are designed for satellite communication has standard specifications.

Locational satellites cannot become functional satellites, and vice versa.

• TRUE

• FALSE

Answer explanation

Locational and functional are just different classifications for the same satellites.
