Dr Dabour Hub Academy - figure 4
Basalt, which cooled quickly at the surface
Sandstone, made of sand grains cemented together
Marble, made by heating limestone without melting it
Granite, which cooled slowly deep underground
7.

Dr Dabour Hub Academy - figure 5
R, then P, then S, then Q
P, then R, then Q, then S
R, then S, then P, then Q

8.
Kareem put 20 g of limestone chips in dilute acid and another 20 g in water, and weighed them every 5 minutes. What is the best conclusion from his graph?
Dr Dabour Hub Academy - figure 6
Water alone breaks limestone down as quickly as acid does
The limestone in acid gained mass because it absorbed the acid
The acid, not the water, broke the limestone down
The acid stopped reacting after 5 minutes because the mass stayed the same
9.
Using the observations in the table, which identification is correct?
K is sedimentary, as it has cemented grains and fossils
J is sedimentary, because its crystals interlock
M is igneous, because its crystals are in bands
L is metamorphic, because its crystals are tiny
10.
Each option pairs a place from the table with a feature expected there. Which pairing is correct?
L4 – many strong earthquakes every year
L3 – fold mountains made as plates pull apart
L2 – no volcanoes and no earthquakes at all
L1 – fold mountains like the Himalayas

Water freezing in cracks and splitting rocks
Layers of sediment being squeezed into new rock
12.
Each option pairs a rock type with an example. Which pairing is correct?

Sedimentary – basalt, formed from cooled lava
Igneous – slate, formed from mudstone
Metamorphic – marble, formed from limestone
13.
Think about what causes each kind of weathering. Which pairing is correct?
Chemical weathering – acid rain reacting with limestone
Biological weathering – water freezing in cracks
Physical weathering – acid rain dissolving rock
Chemical weathering – animals burrowing into rock
14.
Each option pairs a change in the Earth with how quickly it happens. Which pairing is correct?
Earthquake – takes millions of years to happen
Mountain building – very slow, over millions of years
Weathering – happens instantly in one day
Mountain building – sudden, over a few days
15.
Why are most volcanoes found at plate boundaries?
Magma rises where plates part or one sinks below another
Plate boundaries are always the coldest places on Earth
The crust is thickest at plate boundaries, so it holds more magma
Volcanoes form wherever it rains the most
16.
Which sequence describes how a fossil usually forms?
Organism dies → melted by magma → cools into a fossil
Organism dies → buried by sediment → hard parts replaced by minerals
Organism dies → stays on the surface → turns into rock in a year
Organism dies → frozen by ice → forms metamorphic rock
17.
What does the fossil record show scientists?
The exact date of every earthquake
Where magma is found beneath volcanoes
How living things have changed over time
How fast tectonic plates are moving today
18.
Sandstone near the top of a high mountain contains fossil sea shells. What is the best explanation?
Sea animals once climbed the mountain and died there
The shells were made when lava cooled on the mountain
Sea birds carried the shells up from the beach and dropped them there
The rock formed under the sea and was later pushed up by plate movement
19.
In a desert, rock surfaces heat to 50 °C by day and cool to 5 °C at night, again and again. What type of weathering is most likely?
Physical weathering, as the surface repeatedly heats and cools
Freeze–thaw weathering, because the water freezes each night
Biological weathering, because many plants grow there
Chemical weathering by acid rain, which falls daily
20.
Which of these is an example of erosion rather than weathering?
Water freezing in a crack in a boulder
A river carrying pebbles downstream to the sea
Acid rain reacting with a limestone statue
A tree root slowly splitting a large rock apart as it grows
21.
A student wants to model how sedimentary rock forms. Which plan is best?
Melt candle wax and let it cool quickly on a cold tile
Heat a piece of chalk strongly in a flame for 10 minutes
Settle sand and gravel in layers in water, then press them
Freeze a wet sponge and measure how much it expands
22.
Which description of how a volcano forms is correct?
Rain soaks into the ground and boils, forcing rock upwards into a cone
Two plates fold rock layers upwards until a hollow mountain forms
Wind piles up sand into a cone and the Sun heats it until it melts
Magma rises through the crust and erupts; layers of lava and ash build a cone
23.
A class models mantle convection by gently heating a beaker of water containing food colouring over a Bunsen burner. Which is the most important safety precaution?
Wear eye protection and let the beaker cool before touching it
Use a much bigger flame so the experiment finishes quickly
Hold the beaker in your hand to feel the currents
Put a lid on tightly so no colour escapes while heating

30.
The diagram shows a cliff made of sedimentary rock layers containing fossils F, G and H. Statement: fossil H is probably older than fossil F. True or false?
Dr Dabour Hub Academy - figure 7
False – F is older because it is nearer the surface
True – H is in a deeper layer, laid down earlier
False – all fossils in one cliff are the same age
True, but only because plants are older than fish
31.

False – granite gained the most water
True – sandstone and chalk gained far more mass

Metamorphic rocks often have bands or lines of aligned crystals. True or false?
False – they always contain large fossils
False – they are made of rounded grains
True – heat and pressure line up the crystals
