Describe Two ways scientists calculate the age of the universe?
by using the distance from Earth to various galaxies and by calculating the ages of old, nearby stars.
What is the main difference between geocentric and helicentric models of the solar system?
Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
How do scientists calculate the age of the universe?
thry mearsure the distance to the farthest galaxy Answer2. The age of the Universe is around 16 billion light years away or old. There are three completely independent means of measuring the age of our Universe, and all result in about the same age of 12 to 15 billion years: 1) Once a white dwarf is formed, it will remain stable for trillions of years. None have been found older than twelve billion years, however. 2) The inverse of the Hubble Constant -- ie, the time all matter in our observed Universe would return to sub-atomic size -- is about thirteen billion years. 3) Ratios of long-lasting radioactive isotopes to their decay products give close to the same value as (2).
As a star ages what happens to its composition?
A star's internal composition does not change as the star ages, as a result of rising temperatures. The life span of a star is from one to ten-billion years. Larger, more massive stars have a shorter lifespan than smaller ones, due to the pressure on the core causing the larger stars to burn hydrogen more quickly.

Why is the concentration of carbon dioxide rapidly increasing in the Earths atmosphere?
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.

Can carbon ages can be used as independent or dependent variable?
Either. You could have carbon isotope ratios as your independent and carbon age as your dependent. or You could have the carbon age of soil samples as your independent and the artefacts that you are trying to date as the dependent.
Why can't carbon be used to date all ages of material?
The method is limited by the half life of carbon-14 - cca. 5 730 years.
