Our models of the solar system with the sun at the center is called the heliocentric. - 21Describe some examples of how technological advances have led to increased scientific understanding of the solar system.We have modern day telescopes and cameras. Our technology is much more advanced. Which has led to a deeper look in space and much more understanding of it.
- 22How do we know about the universe and solar system?Because we have satellites, telescope and computers to help discover it. We also have a clear view into it from the surface of Earth.
- 23Describe the telescope's importance? Where is the Hubble telescope.Telescopes give us a deep look in space to investigate all different things.
The Hubble telescope is in Earth's orbit in space about 406 000km up and it looks out into space. - 24Describe how advancements in technology have led to a greater understanding of the Universe.We have more technology like telescopes-We can get a deep look into space which shows us answers about size, shape, distance ect.
