Quarter 2 - Summative Test

When tracing a typhoon's path on a map of the PAR, which of the following is the most important factor to include?

• The storm's origin in the Pacific Ocean

• The locations of previous typhoons in the region

• The typhoon's maximum sustained wind speed

• The time intervals of each recorded position

While tracing the path of a typhoon on a map, you notice a sudden change in direction. Which of the following factors is most likely responsible for this shift?

• A decrease in ocean water temperature causing the typhoon to lose energy

• The typhoon encounters a cold front, altering its movement

• A sudden increase in the typhoon's wind speed

• The typhoon's movement is solely influenced by the Coriolis effect

You are analyzing the path of a typhoon that has already made landfall in the Philippines. Which of the following factors is most crucial for predicting the remaining course of the storm?

• Wind speed and direction post-landfall

• The number of typhoons that have made landfall in the past

• The temperature of the landmass

• The salinity of the ocean at the storm's point of entry

Which of the following best describes the primary difference between comets and asteroids?

• Comets are composed mainly of ice and dust, while asteroids are primarily rocky or metallic.

• Comets are located mainly in the asteroid belt, while asteroids are found in the Kuiper Belt.

• Comets move faster than asteroids in space.

• Comets have no tails, while asteroids do.

Which of the following statements best compares the size of comets, meteors, and asteroids?

• Comets are generally the largest, followed by asteroids and then meteors.

• Asteroids are the largest, followed by comets, then meteors.

• Meteors are typically the largest, followed by asteroids, and then comets.

• All three objects are typically the same size.

If you observed a streak of light across the night sky, what would you most likely be seeing?

• An asteroid entering Earth's atmosphere.

• A meteor as it burns up in Earth's atmosphere.

• A comet traveling through the solar system.

• An asteroid collision in space.

Which of the following is a key factor that differentiates meteoroids from asteroids?

• Meteoroids are much smaller than asteroids.

• Asteroids are always found in the Earth's atmosphere.

• Meteoroids are composed mostly of dust, while asteroids are made of solid rock.

• Meteoroids move faster than asteroids.

Which of the following would provide the best evidence for distinguishing between a comet and an asteroid in a telescope observation?

• A comet will have a visible tail, while an asteroid will not.

• A comet will always be closer to Earth than an asteroid.

• An asteroid is composed of gas, while a comet is made of solid rock.

• An asteroid will reflect more light than a comet.

How does the tail of a comet provide insight into the composition and structure of the comet?

• The tail is made of dust and gas that is ejected as the comet is heated by the Sun, revealing the comet's structure.

• The tail contains only frozen gas, which scientists study to determine the comet's age.

• The tail is made of radioactive elements, allowing scientists to trace the comet's origin.

• The tail reveals the comet's interaction with the magnetic field of the Sun.

Which of the following statements best explains the relationship between an asteroid's composition and its albedo (reflectivity)?

• Asteroids made of metals reflect sunlight more strongly than those made of rock.

• Asteroids made of rock reflect more sunlight than those made of metals.

• Asteroids always reflect the same amount of sunlight, regardless of composition.

• Only comets reflect sunlight; asteroids do not.
