32. How will you differentiate a meteor from a comet when viewed from earth? a. A meteor moves fast while a comet moves slow b. A comet and meteor are readily seen on a cloudless night C. A meteor moves slowly while a comet moves fast All of the above 33.What causes meteors to glow when they fall on earth? a. Friction with the atmosphere produces heat and light b. Friction with the atmosphere causes meteors to give off their own light C. Friction with other heavenly bodies produces light Reflection of sunlight 34.When earth orbits the sun and passes through the orbit of a comet, we observe many streak of lights from earth which is called a. Meteor spring b. Asteroids C. Meteor shower d. Meteorite 35. Why does a meteor shower occur? a. When earth orbits the sun and passes through the orbit of a comet b. When a moon orbits the sun and passes through the orbit of a comet C. When a fragment from the meteoroid survives and makes it to the ground d. When it enters earth's atmosphere rt nd 36. Which is NOT happening during a meteor shower? a. We observe many streaks of light from earth b. Meteor seem to originate from only one point in the sky C. Many meteors fall through the atmosphere in a relatively short time d. Meteors collide with neighbouring comet its in d. 20 years 37. How many years it will take for the halley comet orbit the sun? a. 100-150 years c. 10 years b. 75-79 years 38. Which of the following did not tell about the origin of the meteoroid? A. moon b.Asteroids d. Jupiter C. Mars
When viewed from the Earth, a meteor, a celestial body which entered the Earth's atmosphere, can be seen as a streaking light going downwards that is also called by many as a shooting star. Meanwhile, a comet, which did not enter the atmosphere, is also seen to be a streaking light but has a longer tail.
33. B
explanation:
A meteor is a streak of light in the sky caused by a meteoroid crashing through Earth's atmosphere. When a meteoroid enters the Earth's upper atmosphere, it heats up due to friction from the air. The heat causes gases around the meteoroid to glow brightly, and a meteor appears.
34. C
explanation:
A meteor is a streak of light in the sky. A meteor, sometimes called a shooting star or falling star, is actually a space rock that is crashing through Earth's atmosphere. This meteor is streaking across the sky above Chelyabinsk, Russia, in 2013.
35. A
explanation:
Meteor showersoccur when the earth in its orbit around the Sun passes through debris left over from the disintegration of comets. When the earth intersects this orbit in its annual trip, it can run into this debris, which burns up on entry into the earth's atmosphere, producing a visible shower of meteors.
36. B
37. B
explanation:
76 Earth years
Halley's orbit period is, on average, 76 Earth years. This corresponds to an orbital circumference around the Sun of about 7.6 billion miles (12.2 billion kilometers). The period varies from appearance to appearance because of the gravitational effects of the planets.
38. A
explanation:
origin of meteoroids?
Many meteoroids are formed from the collision of asteroids, which orbit the sun between the paths of Mars and Jupiter in a region called the asteroid belt. As asteroids smash into each other, they produce crumbly debris—meteoroids. Other meteoroids are the debris that comets shed as they travel through space.
