Q: What type of field does earth have? Read this paragraph and choose the correct option from the provided answers: Earth has a magnetic field ( Figure below ). The magnetic field has north and south poles. The field extends several thousand kilometers into space. Earth's magnetic field is created by the movements of molten metal in the outer core. Choices: - atmospheric - seismic - force field - magnetic A:
magnetic

Q: What kind of solid is characterized by an unorganized and unpredictable structure? Read this paragraph and choose the correct option from the provided answers: When water freezes in a non-crystalline, amorphous form as frost, the water molecules are fixed in place, but not in a regular, repeating pattern. Frost and other amorphous solids are characterized by their unorganized and unpredictable structure. Because ice comes in both amorphous and crystalline forms, there are differences in the physical properties of ice such as its hardness and density. Choices: - magnetic - aqueous - porous - amorphous A:
amorphous

Q: Heating a gas gives its particles more of what type of energy? Read this paragraph and choose the correct option from the provided answers: In this lesson, you read that heating a gas gives its particles more kinetic energy. As a result, its volume or pressure also increases. The opposite happens when a gas is cooled. Choices: - residual energy - electrostatic energy - nuclear energy - kinetic energy A:
kinetic energy
