Science Review 4th gradeWeek 17The picture below shows sand dunes. What natural force likely shaped this landform? ice water wind gravity

The natural process of breaking down rock into smaller pieces is _______. weathering erosion soil deposition

A teacher made a model of the water cycle like on this picture. In this model, what does the lamp represent? The Earth Evaporation Ocean The Sun

Some animals get their energy from plants. Where do plants get their energy? Air Sun Earth Water

The energy that causes to form water vapor comes from:The cloudsUnderwater mountainsChemical reaction in the seaThe Sun

When a candy bar is heated by the sun, all of the following are likely to be seen EXCEPT the candy bar will be the same the candy bar will change into a liquid the candy bar will melt the candy bar will change its shape A chef is making spaghetti for a large group of people. In order to have enough water, he must boil the water in two different pots. Both pots are metal, but one has wooden handles, and the other has metal handles. What recommendation would you make for handling the two different pots? Use a hot pad to handle the pot with the wooden handles because wood is a good conductor of thermal energy Use a hot pad to handle the pot with the metal handles because metal is a good conductor of thermal energy Use a hot pad to handle both pots, because the handles on both pots will get hot There is no need to use hot pads because neither of the pot handles will get hot. ACBWhich shows the illustrations in order from A to C?Solid, liquid, gas C. Liquid, solid, gasGas, liquid, solid D. Gas, solid, liquid

By creating a closed circuit, an object that needs electricity to operate will work. An example of this would be a light in a room. When the light is working, it creates a closed circuit. If the circuit is open, the light in the room ____________.needs to be changedglows brighteris turned offflickers on and off

What is the process that changes a liquid to a gas? condensation precipitation water cycle evaporation

Which of the following dissolves in water? Sand Salt Dirt OilA student puts a sample of matter in a closed container. The matter takes the shape of the container and spreads out to fill all of the space. What is the state of the sample? Gas Solid Liquid SolutionTo save on heating bills, what should the roof of a building should be lined with? A thermal conductor A thermal insulator Nothing A layer of air

73If one bulb is removed from a series circuit, the other bulbs will ______________. dim get brighter flicker go out

Which sentence describes a liquid?Particles slide past each other.Particles are arranged in a tight patternParticles stay near their neighborsParticles bounce away from each other.

The movement of bits of rock or soil by wind and water is called ________. weathering erosion contour plowing deposition

Can you infer from the picture which rock layer is the oldest?ABCDWhich kind of land is most likely to experience erosion?Flat land because the water will flood and the wind will blow across it.Sloped land because the water will run swiftly down it washing away soil.Flat land because the plants will cover the land and grow forests.Sloped land because the plants will not grow as it is too cold.A ________ has a definite shape. solid sugar-water solution gas liquidFood ChainGrass grasshoppers mice snakesThe arrows show the flow of energy in the food chain. Where does grass get its energy? Wind Rocks the Sun GrasshoppersMost metals are good ________. switches conductors vibrations insulatorsWhich of these is NOT a force?MagnetismWeightHeightFrictionCompleting an experiment one time will assure reliable results. True FalseA gas changes to a liquid by a process called _____. deposition evaporation condensation precipitation
