Natural resources

QuestionAnswer
What are invertebrates? Invertebrates are animals that do not have a backbone
What two types of natural resources are there? Renewable and non-renewable
What are vertebrates? Vertebrates are animals that have a backbone.
What are non-renewable resources? Non-renewable resources are finite. They will run out at some point.
What are fossil fuels? Fossil fuels are non-renewable resources that we burn to make energy.
What are mammals? Mammals are warm-blooded animals (as a dog, mouse, bear, whale, or human being) with a backbone. They feed their babies with milk. Their skin is usually covered with some hair e.g. monkeys, hippos, bears
What are renewable resources? Renewable resources can be replenished naturally (they never finish and we can keep using them)
How was coal formed? Coal was formed millions of years ago from dead plants. Dead plants fell into swamps, they were covered by sediment (dirt and sand) and later pressure and heat turned them into coal.
Why are fossil fuels bad for environment? When fossil fuels are burned they cause pollution
What are crustaceans? Crustaceans are aquatic animals that have several pairs of legs and a body made up of sections that are covered in a hard outer shell e.g. crabs, lobsters, shrimps
What is sediment? Sediment is matter that settles to the bottom of a river, lake, sea, ocean
Why should we protect natural resources? We should protect natural resources because there is a limited amount of non-renewable ones, and the renewable resources still need some time to be renewed so we shouldn't use them all too quickly
What are natural resources? Natural resources are found in nature, people need and use them to make energy
What are birds? Birds are warm blooded animals which have feathers, a beak, no teeth, wings and lay eggs.
What are fish? Fish are cold-blooded animals that live in water, have gills for breathing, skeletons inside their bodies, and scales on their skin
What are arachnids? Arachnids are invertebrates that have a segmented body and 8 legs e.g. spiders, scorpions.
What are mollusks? Mollusks are invertebrate animals with a soft body usually enclosed in a shell e.g. snails, clams, squids
What are amphibians? Amphibians are cold-blooded vertebrate animals that have gills and live in water as larvae but breathe air as adults e.g. frogs, toads, newts
What are reptiles? Reptiles are cold-blooded animals that breathe air and usually have the skin covered with scales or bony plates e.g snakes, lizards, turtles, alligators
What do we use fossil fuels for? Fossil fuels are used to fuel cars and airplanes, power electricity plants, and heat our homes, make medicines, cosmetics, plastics, synthetic fabrics
What do we use minerals for? Minerals are used to make various objects e.g. jewellery (gold, silver, diamonds), electronics, glass (quartz), pencils (graphite), pipes (copper)
What are rocks? Rocks are solids made up of of different minerals. There are three types of rocks: Metamorphic, Igneous, and Sedimentary.
What are crystals? Crystals are a special kind of solid material where the particles fit together in a repeating pattern. This pattern causes the material to form all sorts of unique shapes that look beautiful.
What are minerals? Minerals are solid substances that occur naturally. They can be made from a single element. The Earth is made up of thousands of different minerals.
What are igneous rocks? Igneous means made of fire.Igneous rocks are formed when molten lava comes out of earth's surface ,it cools and turns into solid rock.
What are metamorphic rocks? Metamorphic rocks have been changed over time by extreme pressure and heat. Metamorphic rocks can be formed by pressure deep under the Earth's surface, or from the extreme heat caused by magma.
What are sedimentary rocks? Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are turned to rock.
What are the characteristics of minerals? Minerals are solid, natural, and inorganic. They have a specific chemical structure
How was oil formed? Oil was formed millions of years ago from dead sea creatures that fell to the bottom of the ocean, were covered by sediment and with pressure and heat turned into oil.
How was natural gas formed? Natural gas was formed millions of years ago from dead sea creatures that fell to the bottom of the ocean, were covered by sediment and with pressure and heat turned into oil.
What do we use coal for? We burn coal in power plants to make electricity, but also to heat buildings. In the past we used coal on ships and in trains to make eneergy for them to travel.
What do we use crude oil for? We use crude oil to make gasoline for cars, to make asphalt, to make poliesther, candles, plastic
What do we use natural gas for? We use natural gas to make electricity, to heat water and buildings
How do we get coal? We extract it in mines
How do we get crude oil? We need to pump it from underground, we can do it on land or on sea
Where do we get minerals from? We can mine for minerals or get them from the water in which they dissolved
