What is the difference between a graph and a data table?

A graph represents the data visually, and a data table represents the data numerically.

A data table represents the data visually, and a graph represents the data numerically.

A data table represents the data in percentage form, and a graph represents the data in decimal form.

A graph represents mathematical data, and a data table represents scientific data.

How does Hubble time estimate the age of the universe?

Hubble time measures the distances between galaxies and the time they take to expand.

Hubble time measures the distances between galaxies and the time they take to shrink.

Hubble time measures the amount of time that planets in other galaxies orbit their sun.

Hubble time measures the radiation levels from the sun and the time they take to reach the surface of the planets.

Why is the Big Crunch a hypothesis and not a theory like the Big Bang?

In contrast to the Big Bang theory, the Big Crunch does not have enough data and evidence to support it.

The Big Crunch is based on data and measured evidence, and the Big Bang is based on an educated guess.

The Big Crunch is a new idea and has not been around as long as the Big Bang theory. In order for a hypothesis to change to a theory, scientists must discuss the idea for more than ten years.

The Big Crunch is based on the idea that the universe has been shrinking since day one. The idea cannot be a theory if it is not based on the universe expanding.

What is the 'first second' in relation to the Big Bang theory?

the formation of the Milky Way galaxy

the moment the planets began their orbits around the sun

How does the galaxy movement theory support the big bang theory?

The big bang theory states that the universe is expanding. Scientists can look back in time to galaxies beyond the Milky Way and calculate how long it takes the galaxies to expand and move to their present destinations.

The big bang theory states that the universe is shrinking. Scientists can look back in time to galaxies beyond the Milky Way and calculate how long it will take them to shrink and move to their future destinations.

The big bang theory states that the universe does not evolve or change and that it has, in fact, stayed the same since its formation. Scientists can study galaxies and see that they have not evolved or moved, which supports the big bang theory.

The big bang theory states that, over time, galaxies move and combine with other galaxies. Scientists can observe this movement and note when planets join different galaxies.

How does the composition of the universe support the big bang theory?

The elements helium and hydrogen remain prevalent in the universe. These same elements were formed minutes after the big bang.

The elements helium and hydrogen are almost nonexistent in the current universe. The fact that the universe is evolving suggests that these elements might change into different elements over time.

Over time, the elements that make up the universe have evolved and have therefore created new elements that did not exist when the universe formed.

When the universe formed, it was composed of stars, planets, and other celestial objects. Though the universe is evolving, these components are still present.

The universe has both clusters and voids. What is the difference between these two areas?

Voids are areas where there is little matter and no galaxies. Clusters are areas with many galaxies.

Clusters are areas where there is little matter and no galaxies. In contrast, voids represent areas with many galaxies.

Voids are areas that have only elliptical galaxies, and clusters are areas that have only irregular galaxies.

Clusters are areas that have only elliptical galaxies, and voids are areas that have only irregular galaxies.

What is the correct hierarchy of structures within the universe starting with the smallest in size?

planet, solar system, galaxy, galaxy cluster

galaxy cluster, galaxy, solar system, planet

solar system, galaxy, planet, galaxy cluster

galaxy, planet, galaxy cluster, solar system

What feature makes our solar system a heliocentric solar system?

All the planets revolve around the sun.

All the planets revolve around Earth.

All the planets revolve around their own moon.

All the planets have a retrograde rotation on their axis.

What is the difference between wavelength and frequency?

Wavelength represents the distance between two crests or troughs, and frequency represents the number of waves that occur in an amount of time.

Frequency represents the vertical distance between the center line and peak, and wavelength represents the top-most part of the wave.

Wavelength is the lowest part of the wave, and frequency is the highest part of the wave.

Frequency represents the distance between two crests or troughs, and wavelength represents the number of waves that occur in an amount of time.

How are the speed of light and a light-year different?

Both are measurements but differ in what they measure. The speed of light is a measurement of speed, and the light-year is a measure of distance.

Scientists can use the speed of light to look back at galaxies formed during the Big Bang, but a light-year cannot be used to look back at these galaxies.

Both are measurements but differ in what they measure. A light-year is a measurement of speed, and the speed of light is a measure of distance.

Light-years measure distances within the solar system, and the speed of light measures distances outside of the solar system.

What is the difference between a scientific law and a scientific theory?

A scientific theory explains how and why something happens. A scientific law describes what happens without explaining how or why.

A scientific law explains how and why something happens. A scientific theory describes what happens without explaining how or why.

A scientific theory is accepted without scientific testing, and a scientific law is accepted when it is proven to explain how and why something happens.

A scientific law is an idea that has not yet undergone experimental testing, and a scientific theory is a law that has undergone experimental testing.
