Science Quiz - 2

Question 1

Gases that make up the sun

Answer 1

Hydrogen and Helium

Question 2

Nuclear Fusion

Answer 2

When gasses in the sun mix in together forming stars

Question 3

Ancient Greece Observations

Answer 3

They believed that the universe was perfect and earth was the center of the whole thing

Question 4

Sun’s gravity

Answer 4

The Sun’s gravity pulls on the planets, just as Earth’s gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Question 5

Sun’s characteristics

Answer 5

The sun is about 1.3 million times bigger than the earth. Medium mass, medium bright, in between yellow

Question 6

Sun’s interior

Answer 6

Core, where nuclear fusion occurs, huge amounts of energy is produced, is 15.7 million Kelvin

Question 7

Sun’s atmosphere

Answer 7

Photosphere, chromosphere, and corona

Question 8

Photosphere

Answer 8

Electromagnetic spectrum, gives off visable light, the surface layer

Question 9

Chromosphere

Answer 9

Is that red part that is seen only during solar eclipses, is the second layer of the atmosphere

Question 10

Corona

Answer 10

The halo that is seen during a solar eclipse, is the last layer of the atmosphere

Question 11

How hot is the sun

Answer 11

The sun is 5,778 Kelvin

Question 12

Answer 12

Is a primary source of energy, the sun gives us food

Question 13

Ptolemy

Answer 13

Question 14

Nicolaus Copernicus

Answer 14

Figured out the arrangement of the plantes, and how they moved around the sun = heliocentric theory earth is other plants move around the sun

Question 15

Tycho Brahe

Answer 15

Observed the positions of the planets

Question 16

Johannes Kepler

Answer 16

Agreed with Tycho Brahe, found the orbit of each planet is an elipse

Question 17

Sir Isaac Newton

Answer 17

Stated that inertia and gravity keep planets in orbit

Question 18

Radiation zone

Answer 18

Region of very tightly packed gas, where the energy is mainly transferred, it’s extremely dense, is the second layer of interior

Question 19

Convection zone

Answer 19

The outer layer of the inside, gasses gradually cool as they reach the top, forming loops of gas that moves energy toward the sun’s surface

Question 20

Sunspots

Answer 20

Can be larger than earth, are areas of gas on the sun’s surface. Sun spots appear to move, proving that the sun rotates on its axis.
