The cards Question What are the grains in a rock? Tap to flip Answer The individual pieces that make up the rock. Question What does a rock's texture describe? Tap to flip Answer The size and shape of its grains, and how the grains are arranged. Question What is a crystal? Tap to flip Answer A solid whose particles have a highly ordered arrangement; it often has a regular shape. Question What are interlocking grains? Tap to flip Answer Grains that lock together like a mosaic, with no gaps between them. Question The grains in a rock can be round or what? Tap to flip Answer Interlocking. Question To classify a rock, what is more useful than its colour, shape or size? Tap to flip Answer Its texture: its grains and how they are arranged. Question What is a mineral? Tap to flip Answer A naturally occurring pure substance (an element or a compound) that has a crystal structure. Question What is a rock? Tap to flip Answer A solid substance that is a mixture of minerals; it makes up any solid part of Earth. Question Besides minerals, what else do rocks consist of? Tap to flip Answer Rock fragments. Question Give one thing used to identify a mineral. Tap to flip Answer Its crystal structure, its composition or its physical properties. Question What does 'crystalline' describe in a rock? Tap to flip Answer A rock made of interlocking crystals. Question How do sedimentary rocks form? Tap to flip Answer From the compression of sediments: rock fragments, minerals and remains of dead plants and animals. Question What is a metamorphic rock? Tap to flip Answer A rock that has changed due to heat and/or pressure, e.g. marble or slate. Question What are igneous rocks formed from? Tap to flip Answer Magma, either erupted from a volcano or cooled below ground. Question What is a porous rock? Tap to flip Answer A rock with spaces between its grains. Question Is a rock with interlocking crystals porous or non-porous? Tap to flip Answer Non-porous. Question How do the crystals in igneous rocks differ from those in metamorphic rocks? Tap to flip Answer In igneous rocks they point in many directions; in metamorphic rocks they mostly line up. Question What is Earth's crust? Tap to flip Answer The rocky, outermost layer of Earth. Question What is the layer of dense rock below Earth's crust called? Tap to flip Answer The mantle. Question Over very long geological time scales, how do parts of the mantle behave? Tap to flip Answer As a fluid. Question What is Earth's outer core? Tap to flip Answer A liquid layer of mostly iron and nickel between the mantle and the inner core. Question What is Earth's inner core? Tap to flip Answer A solid ball of mostly iron at the centre of Earth, inside the outer core. Question How do temperature and pressure change towards the centre of Earth? Tap to flip Answer They increase. Question Why do scientists use models? Tap to flip Answer To represent parts of the natural world that are difficult to observe or explain directly. Question What did the theory of continental drift propose? Tap to flip Answer That Earth's continents were once one landmass and gradually drifted apart over time. Question What is the part of Earth's crust found below oceans called? Tap to flip Answer Oceanic crust. Question What is the part of Earth's crust found below landmasses called? Tap to flip Answer Continental crust. Question What does a tectonic plate consist of? Tap to flip Answer Earth's crust and the uppermost mantle beneath it. Question What do earthquakes and volcanic eruptions suggest about Earth's layers? Tap to flip Answer That they are not static but interact with each other. Question What does the theory of plate tectonics explain? Tap to flip Answer How tectonic plates move and interact with each other. Question Besides convection currents, give one process in current ideas about what drives plate movement. Tap to flip Answer Slab pull or ridge push. Question What is lava? Tap to flip Answer Molten rock that has broken through Earth's crust. Question What is magma? Tap to flip Answer Molten rock beneath Earth's surface. Question What is crystallisation? Tap to flip Answer A process in which solid crystals form as molten rock cools. Question Where do extrusive igneous rocks form? Tap to flip Answer Above Earth's surface, when lava cools and crystallises. Question Where do intrusive igneous rocks form? Tap to flip Answer Under Earth's surface, when magma cools and crystallises. Question What does the size of crystals in igneous rock depend on? Tap to flip Answer The rate at which the melted rock cools. Question Which two things decide the type of igneous rock that forms? Tap to flip Answer The mineral composition of the lava or magma, and the rate of cooling. Question How are the atoms arranged in a crystal? Tap to flip Answer In a very regular pattern. Question Under what conditions do metamorphic rocks form? Tap to flip Answer Extreme pressure and temperature. Question Where are the temperatures and pressures needed for metamorphism typically found? Tap to flip Answer At plate boundaries or hot spots.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
