Question

I need help with a few definitons. Thanks

Answer 1

This is the first one.

Answer 2

All of the planets in the solar system have (blank) with the expectation of Mercury and Venus.

Answer 3

The answer is moons because Mercury and Venus are too small of a planet to have the gravitational strength to have a moon orbiting it. A small asteroid type rock would be possible but that is not considered a moon. All of the other planets do have moons orbiting them in our solar system.

Answer 4

Can you help me on somemore please? I don't know any of these:(

Answer 5

Sure, post them up and i'll answer the ones you need :)

Answer 6

thank you! You're a lot of help!

Answer 7

Because there is no (blank) on the moon, any liquid water would have evaporated into space long ago.

Answer 8

An atmosphere because if Earth did not have an atmosphere, the sun's ultraviolet rays would easily evaporate all of the water on Earth.

Answer 9

How do you know all of this? Do you study science??

Answer 10

The length of a planet's day is determined by its (blank).

Answer 11

Well, i'm going to grade 12 so all of this stuff is basic stuff for me :P

Answer 12

Lol, can I know what grade you? These questions should be really easy :3

Answer 13

I'm only in 9th:( I hate school. I'm so terrible at it. When I graduate I'm not even going to go to regular college. I'm just going to hair school and then I'm OUT.

Answer 14

Oh haha, well that explains it. Anyways, don't worry about school, just follow your dreams and compassion of what you want to do in the future! The answer is rotation or orbit of the planet because think about it, the only reason we have a 24 hour type time is because it takes 24 hours for the Earth to rotate 360 degrees to restart it's day depending upon the Sun.

Answer 15

I put axis :0 I would have failed without you:/ here's my next question.


The large, irregular objects mostly located between Mars and Jupiter are (blank)

Answer 16

Well, the only object there is in space between Mars and Jupiter are asteroids and since asteroids are large and irregular objects, that's the answer :P

Answer 17

Icy objects that mostly travel in long, elliptical orbits around the sun are (blank).

Answer 18

I thought this one was comet.

Answer 19

Yeah, it would be comet, good job :)

Answer 20

OMG YAY<3

Answer 21

The (blank) belt contains perhaps tens of thousands of objects orbiting within about 100 AU of the sun.

Answer 22

Hmmm yeah this would be a question from grade 9, i'm pretty sure it would be the Kuiper belt which is similar to the asteroid belt but a lot more bigger. And it is around 50 to 100 AU from the sun so yeah.

Answer 23

I've never even heard of that belt D;




The material that formed the solar system originated from a solar (blank).

Answer 24

I guess you learned only about the asteroid belt, I think you would either learn about the Kuiper belt in grade 9 or 10. Anyways, the answer would be a nebula because a nebula's basically a interstellar cloud of like hydrogen, helium, dust and other gases. And after a long time, all of these materials clumped together to produce our solar system due to the gravitational pulls upon the clumped up gases and dust.

Answer 25

Nuclear fusion within the sun takes place within the (BLANK).

Answer 26

I'm sure you know this answer, think about it! Where would be the only place that nuclear fusion is, or in other words, where on the sun is the hottest place?

Answer 27

the middle?

Answer 28

Yeah! Or in other words, the core.

Answer 29

Alright, for the next questions you have, post them up and tell me what you think the answer is and i'll tell you if it's right or wrong. This will help you a lot in learning all of this.

Answer 30

okay now this one is really hard for me. I had no idea what it was asking me.


In an H-R diagram, most stars are found in a diagonal band from the upper left, to the lower right , which is called the (BLANK)

Answer 31

I thought the answer to this one was diagonal... Cause I can't think of anything else

Answer 32

So this question shouldn't be given unless your teacher taught you this since this is a grade 10 question because I learned this last year. The H-R diagram is a Hertzsprung–Russell diagram which is basically a scatter graph of stars showing the relationships between the star's luminosites (brightness in other words) versus their temperature. The only way you would know the answer to this question is if you learned about the H-R diagram and what it is. Anyways, the answer is the main sequence.

Answer 33

oh wow! Yeah cause I don't remember learning this at all.

Answer 34

Describe a technology used in space exploration.

Answer 35

There are TONS of technology used in space exploration, I guess you can use the land rover that was used on Mars.

Answer 36

hold on real quickl(:

Answer 37

yeah sure

Answer 38

I need your help! @DaebakJoo

Answer 39

What formed the moon's maria?

Answer 40

Sure

Answer 41

Oh and can you explain to me what a maria is..

Answer 42

Uhh, i'm not really sure about this one since I never really learned about it o.o

Answer 43

I don't know this either O.O

Answer 44

How about this one?



What is the current hypothesis on how Earth's mooned was formed?

Answer 45

Uhmm The current hypothesis is basically an impact by a Mars-sized object like a large asteroid hit the Earth which ejected tons of material like dust and debris which then collected to form the moon.

Answer 46

What two factors cause a nebula turn into a star?

Answer 47

to develop into a star.

Answer 48

In order for a star to form, it must have dust and all of the debris from the nebula clump up to create a center of gravity. As more and more clumps of dust and gasses clump up together, the gravitational strength increases exponentially. Also, the pressure within the center of it is what creates a star.

Answer 49

you're so smart!

Answer 50

Okay I really need help on this! I'm gonna have to draw a picture!1

Answer 51

here's the question to the picture.



In the figure below, which components of the solar system are indicated by orbits 1-9? Name each component in order from the sun and classify each.
