100
Write the Earth, Moon and Sun in order from smallest to largest.
Moon -> Earth -> Sun
100
What are the four seasons?
Summer, Autumn, Winter, Spring
100
What does this diagram show?
Lunar Eclipse
100
What are the two factors that effect gravitational pull?
Mass and Distance
100
What is the definition of a renewable resource?
Something that can be replenished within a lifetime (100 years)
200
Out of the Earth, Moon and Sun, which one has the greatest gravitational pull?
The Sun, because it has a greater mass.
200
What causes the seasons? You may like to draw a diagram.
The Earth is tilted on an axis, causing one hemisphere to be closer or further away from the sun.
200
What does this diagram show?
Solar Eclipse
200
What is a spring tide?
A larger tidal effect due to the the sun and moon aligning.
200
Is coal renewable or non-renewable. Explain your answer.
Non-renewable because it takes hundreds/thousands years to form.
300
How long does it take for the Earth to complete on rotation on its axis?
24 hours.
300
If the southern hemisphere is tilted towards the sun, what season are the exeriencing?
Summer.
300
Can eclipses be seen from all parts of the Earth at the same time?
No, it can only be seen from certain places because the Earth, Moon and Sun need to be in line.
300
What is a neap tide?
A smaller difference between high and low tide due to the sun and moon being at a 90 degree angle to Earth, cancelling out the gravitational pull.
300
What are two disadvantages to using fossil fuels?
Non-renewable
Greenhouse gases are produce
Can harm/destroy ecosystems through mining.
400
How long does it take for the Earth to do one revolution around the sun?
365.25 days
400
If the northern hemisphere is tilted away from the sun, which season are they experiencing?
Winter
400
Name two phases of the moon.
Full moon, gibous, quarter moon, new moon
Waxing/Waning
400
What time is the highest tide?
2:51pm and 3:25pm
400
What are some examples of renewable energy sources?
Wind
Solar
Hydro
Geothermal
500
Why is it not sunlight for 24 hours a day?
Earths rotation causes the Earth to be turned away from the sun for half of the day
500
If an asteroid hit Earth and changed the tilt of its axis, what impact would that have on the seasons?
If the earth's tilt increased the seasons would become more extreme. If the tilt decreased the tilt would become less extreme.
500
What causes the phases of the moon? Is the moon changing size/shape?
The moon phases are caused by the amount of sunlight being reflected off the moon and the angle and position of the moons orbit to Earth.
500
What time is the lowest tide?
8:31am and 8:36pm
500
What does sustainable mean?
Sustainable means something that can be continued for a long period of time/many generations.
