What is the name of the phenomenon that most likely created our universe?
The big boom theory
The giant bang theory
The cosmic explosion theory
The big bang theory
Which of the following statements is NOT true about the Big Bang Theory?
At first, our universe was in a hot and extremely dense state.
Then, it exploded and created space (tér), energy, matter and time.
As the radiation from the explosion decreased, the first atoms were formed, mostly carbon and iron.
Atoms formed atomic clouds, and the gas within them had enough gravity to cause more atoms to collect. They will form the core of stars.
A large collection of stars, dust, and gas held together by gravity is a.........

What happens in the core of a star?
hydrogen and helium atoms are created
nuclear fusion
hydrogen atoms cool helium atoms down
other stars born
What can we use to measure the distance of objects in our solar system?

Astrological kilometre
Light- year
Which statement is TRUE about our Sun?
It has 2 movements: orbits the nuclear bulge of our galaxy system and rotates around its axis.
It mostly consists of iron and oxygen.
The nuclear fusion reactions in its core produce the gravity of Earth, thus making our planet habitable.

It keeps the axis of our planet tilted.
Which statement is not true about the motions of the Earth?
It rotates around its axis.
It rotates around the Moon.
It revolves around the Sun.
It revolves around the bulge of the galaxy.
One of the following pieces of evidence about the shape of our planet is incorrect. Which one?

The angle from which sunlight reaches Earth is the same everywhere on the planet.
According to multiple satellite images, our planet is a sphere/globe.
We can see that Earth’s shadow projected on the Moon is an arc.
What are the dark features/areas of the Moon?
highlands
mountains
frozen seas
impact basins (large complex craters)
