How can you use the products of photosynthesis to help reduce levels of harmful air pollutants?
you can reduce this by trying to reduce air pollution in the gases that get caught in many layers of earth. so the air pollutants cause green house gases, and we can help reduce by riding bikes, saving paper, brown bags, any bottles, glass, and fuel would become rare which we shall always have in the first place.-Stephanie-advance physics-12-
What composes all living things?
All living organisms are made of cells However, all objects in the universe (including living organisms) are composed of, according to current understanding, fundamental particles which are quarks and leptons. (Some objects are not made up of atoms such as neutron stars)
The apparent motion of the sun in the sky is caused?
Stars move very fast through space (millions of miles per hour), but because of our distance from them, they appear to move very slowly if at all. The stars we see move the most are the Sun and moon and the other 7 planets of the Solar System. The Sun and stars moves across the sky because the Earth revolves upon its axis, which causes us to see days and nights. The movement of the moon is due to its orbiting the earth and the constant spinning of the Earth. Because the Earth spins, the moon rises approximately 40 minutes later each day. The movement of the planets is caused by their orbit of the Sun and also the Earths. As we go around the sun, our vantage point changes, so objects in the sky appear to move more than they actually do.
Where on the earth does the earth get the most light?
Near the equator.
What is everything that is alive on earth made of?
Earth is only made of rock and has gravity.
What does analysis of colors tell astronomers about objects in space?
Doppler shift tells the distance form the earth station
Most ancient astronomers thought that all celestial objects revolved around?
Earth. I had the same question on a science packet.
Arab Astronomers determined that the earth was what?
Arab astronomers determined that the Earth is flat.
Indian astronomers recognized that earth?
India astronomers recognized that the earth was a sphere.
Why are astronomers interested in mass extinctions on Earth?
Astronomers know that just as large objects from space have cause catastrphes on Earth in the past they are likely to do so again in the future. By finding such objects and calculating their paths they learn which ones have paths that intersect Earth's orbit. By calculating when and where that will happen they discover which ones are a threat to Earth. With such advance warning they can send a spacecraft to the object to change its path so it is no longer a threat. For example, astronomers know that a large object will pass close to Earth on Friday the 13th of April 2029. It will miss Earth, but it will be so close that it will be closer than our communication satelites.
How do astronomers solve the problems with earth based telescopes?
Adaptive optics which change the shape of large mirrors during observation have helped to reduce atmospheric distortion.
What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
Why do astronomers move their telescopes when observing the sky?
To compensate for the motion of the Earth in order to observe a fixed object, such as a distant star. Relative to the Earth, distant objects do not move, but the Earth rotates and orbits the sun, thus all objects appear to move relative to a fixed point on the Earth. Therefore telescopes (which are fixed points) must move to compensate for this motion.
Astronomers collect data about space by?
astronomers collect data by diverse technical equipment: - by space probes -by telescopes -by satellites -and by other technical equipment In general they often also use radiometry/radiation and take pictures of astronomic objects, sometimes they also land on some objects and take samples, sometimes also by meteorites (that strike on earth).
Why do you think that astronomers are considered to be e Earth scientists?
Because you study earth and science and astronomy is study of stars and planets. So I think astronomers are a scientist of earth dont you!:)
What kind of scientist studies the universe and the planets galaxies stars and other objects within it?
Astronomers and physicists.
What planet do astronomers believe there is life?
Earth
