Question 10

define what a “day” is

Answer 10

A day is the time it takes for Earth to spin around on its axis once completely.

Question 11

What causes the seasons to occur

Answer 11

earth’s tilted axis causes the sunlight to be more concentrated on some parts of Earth than others at different times of the year. this causes the seasons

Question 12

what is the degree of Earth’s axis tilted at

Answer 12

23.5°

Question 13

what is the equator

Answer 13

an imaginary line that goes around Earth that divides it into 2 equal halves, the southern hemisphere (Australia) and the northern hemisphere (America)

Question 14

what does the equator have to do with the seasons

Answer 14

the two hemispheres experience opposite seasons due to one half being closer to the sun than the other. (Australia=Summer, America=Winter)

Question 15

define solar eclipse

Answer 15

it’s when the moon passes between the Sun and Earth causing the Moon’s shadow to block the Sun’s rays from hitting Earth

Question 16

the moon’s inner shadow (during an eclipse) is called what

Answer 16

the umbra

Question 17

what is the moon’s faint shadow called (during an eclipse)

Answer 17

the penumbra

Question 18

define lunar eclipse

Answer 18

when the Earth moves between the sun and the moon therefore, blocking the sun’s rays from hitting the moon.

Question 19

during a lunar eclipse the observer would see

Answer 19

the shadow of the Earth slowly move across the surface if the Moon, covering it. Sometimes it turns the moon’s surface red.

5. full moon
6. waning gibbous
7. last quarter
8. waning crescent

Question 21

how long does it take the moon to cycle through all its phases

Answer 21

29.5 days
-this is known as one lunar month

Question 22

how many times a year do we see a full moon

Answer 22

12 or 13 times

Question 23

explain why we can only see 1 side of the moon

Answer 23

The moon spins on its axis once in precisely the same amount of time that it takes to orbit the Earth once, that we only ever see one side of it because of the way both planets orbit.

Question 24

what moon phase is the lunar eclipse seen at

Answer 24

full moon

Question 25

what moon phase is the solar eclipse seen at

Answer 25

new moon

Question 26

why do phases of the moon occur

Answer 26

the sun’s rays reflect off the moon at different angles as it orbits Earth and as Earth revolves around the Sun.

Question 27

describe the geocentric model

Answer 27

the geocentric model places Earth at the centre of the universe. The moon, sun, other planets, and stars all revolve around it
-this is not correct the sun is in the middle of the universe

Question 28

describe the heliocentric model

Answer 28

the heliocentric model of the solar system places the sun at the centre. The Earth, and other planets revolve around it.
-this is a correct representation of where we are in space

Question 29

which planet is closest to the Sun

Answer 29

Mercury

Question 30

how many planets are in our solar system

what are the 4 outer, gas giants

Answer 32

-Jupiter
-Saturn
-Uranus
-Neptune

Question 33

what is the order of the planets

Answer 33

Mercury, venus, earth, mars, jupiter, saturn, uranus, neptune

Question 34

what are the two types of satellites

Answer 34

1. natural satellites, bodies that orbit around planets (the Moon)
