The Movements Of The Earth and The Moon

The Movements Of The Earth

1. The Earth moves around the Sun in their own path.
2. The path is called the orbit.
3. Each planets have their own orbit. The bigger the size of the orbit is, the longer the time taken takes by planet to complete one revolution moves around the sun.
4. The Earth takes around 365 days to complete one revolution moves around the sun.




The Movement Of The Moon

1. The Moon moves around the Earth in their own path.
2. The path is called the orbit.
3. The Moon takes around 27 days to complete one revolution moves around the Earth.
4. The movement of the Moon can cause the phases of the moon.
5. The phases of the moon shown in diagram below.

Rotation Of The Earth

Note :-
1. Earth rotates its own axis from west to east.



2. The Earth takes 24 hours to complete one rotation.
3. The rotation of the Earth can cause:-
a) The changing the direction and length of the shadow.


b) The occurrence of the day and night

Pre-PKSR 2 Answer

Question 1

(a) Increasing / Increases / Increase
(b) Because the liquid Q becomes neutral
(c) pH value of liquid Q
(d) The volume of soap water added increasing / increases / increase // more, so the pH value of liquid Q increasing / increases / increase // more // Vice Versa
(e) To study / investigate / find out the realtionship between the volume of soap water added and / with the pH value of liquid Q

ANSWER-TRIAL UPSR 2010

Section B

Question 1

(a) Because animals in cage Z is more active than animals in cage Y //

Cage Z puts under sunlight than cage Y puts indoor

(b) Decrease, increase, decrease, increase, decrease

(c) 1. Time

2. Air temperature of animals cage

3. Type/size/number of animals

(d) The air temperature in cage Z higher than air temparature in cage Y / (vice versa)

Question 2

(a) To study/investigate/find out the relationship between the time/position of the sun and/with direction of the shadow.

(b) Time // Position of the sun // direction of the shadow // height of pupils /Kelvin / place of the investigation.

(c) Position of the sun is at the west, direction of the shadow is at the east / (vice versa)

(d) Because the rotation of the Earth on its own axis from west to east.

Question 3

(a) To study/investigate/find out the relationship between the size of container/surface area and/with volume of water after one hour.

(b) Volume of water in each container decreasing because the water evaporate to the surrounding.

(c) Air humidity // Air movement // Surrounding temperature

(d) The sorrounding temperature increase / more, the volume of water left decrease / less // (vice versa)

Question 4

(a) Because Q is having total eclipse // umbra.

(b) Surrounding temperature decreasing // the Sun suddenly disappear.
