The cards Question What is weathering? Tap to flip Answer The wearing down or breaking of rocks while they stay in place. Question What are the three types of weathering? Tap to flip Answer Biological, chemical and physical. Question What is erosion? Tap to flip Answer The breakdown and removal of rock material by flowing water, wind or moving ice. Question In freeze-thaw weathering, what widens the cracks in a rock? Tap to flip Answer Water in the cracks freezes and expands, gradually wedging them open until the rock breaks. Question Is freeze-thaw a physical, chemical or biological weathering process? Tap to flip Answer Physical. Question What is sediment? Tap to flip Answer Material deposited by water, wind or ice, such as pebbles, sand, or salts left by evaporation. Question What is deposition? Tap to flip Answer Sediment grains settling out of water or wind as the flow slows, or as ice melts. Question What is compaction of sediment? Tap to flip Answer Sediment grains being squashed closer together by pressure during burial. Question What is cementation of sediment? Tap to flip Answer Sediment grains being stuck together by minerals deposited from groundwater, turning the sediment into rock. Question What are strata? Tap to flip Answer Layers of rock formed by the deposition of sediment. Question What kind of timeline can strata be used to create? Tap to flip Answer A relative timeline. Question In which type of rock are fossils found? Tap to flip Answer Sedimentary rock. Question How can bones buried in sedimentary rock become fossils? Tap to flip Answer They are very slowly dissolved by water and replaced by minerals from the water. Question What is the rock cycle? Tap to flip Answer The gradual recycling of rocks over millions of years. Question What can geological activities do to fossils? Tap to flip Answer Break them or completely destroy them. Question What is a mineral? Tap to flip Answer An element or compound with a crystal-like structure; minerals are the building blocks of rocks. Question Why does coal burn? Tap to flip Answer It is made mostly of carbon. Question What type of rock is coal? Tap to flip Answer Sedimentary rock. Question What was coal formed from? Tap to flip Answer Deep sediments of organic matter made of prehistoric plants. Question What did oil and natural gas form from? Tap to flip Answer Dead plankton mixed in with sediments millions of years ago. Question Where are oil and natural gas found? Tap to flip Answer In the pores of sedimentary rock. Question What are plankton? Tap to flip Answer Microscopic aquatic plants and animals. Question What are hydrocarbons? Tap to flip Answer Molecules made of hydrogen and carbon atoms only. Question Why are fossil fuels not a renewable energy resource? Tap to flip Answer They take millions of years to form and are being used faster than they are produced. Question What percentage of Earth's atmosphere is nitrogen? Tap to flip Answer 78%. Question What percentage of Earth's atmosphere is oxygen? Tap to flip Answer 21%. Question Within what height of Earth's surface is most of the atmosphere? Tap to flip Answer Within 7 to 15 km. Question What is the test for oxygen gas? Tap to flip Answer It relights a glowing splint. Question What is the test for carbon dioxide gas? Tap to flip Answer It turns limewater milky (a white precipitate forms). Question What is a precipitate? Tap to flip Answer An insoluble solid formed when two solutions react together. Question Which atoms make up one molecule of carbon dioxide? Tap to flip Answer One carbon atom and two oxygen atoms. Question Which atoms make up one molecule of methane? Tap to flip Answer One carbon atom and four hydrogen atoms. Question What gas is commonly made when fuels containing carbon are burned? Tap to flip Answer Carbon dioxide. Question What is a greenhouse gas? Tap to flip Answer A gas that contributes to global warming by reducing the amount of radiation leaving Earth's atmosphere. Question What is global warming? Tap to flip Answer The increase in Earth's global temperature, likely caused by higher levels of greenhouse gases in the atmosphere. Question What is the carbon cycle? Tap to flip Answer The process by which carbon is transferred between the atmosphere, organisms and Earth. Question Give one process that increases the amount of carbon dioxide in the atmosphere. Tap to flip Answer E.g. combustion, respiration or decomposition. Question Which process carried out by plants, phytoplankton and some bacteria reduces carbon dioxide in the atmosphere? Tap to flip Answer Photosynthesis. Question What is decomposition? Tap to flip Answer The breakdown of dead organic matter by microorganisms. Question What is combustion? Tap to flip Answer An exothermic reaction in which a substance reacts with oxygen, releasing heat to the surroundings. Question Are carbon atoms created or destroyed in the carbon cycle? Tap to flip Answer No. The total amount of carbon stays constant; carbon is transferred from one place to another.

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.
