KSA Science Grade 4 Quiz

What are the three main types of rocks?

• Igneous, sedimentary, and metamorphic

• Solid, liquid, gas

• Hot, warm, cold

• Red, blue, green

How are igneous rocks formed?

• From the compression of sediment

• From the solidification of molten rock material

• From the evaporation of water

• From the cooling of organic matter

What are the characteristics of sedimentary rocks?

• Contain no fossils

• Formed by accumulation and compression of sediments, often contain fossils, layered or stratified

• Formed by volcanic activity

• Not layered or stratified

What is the difference between metamorphic and igneous rocks?

• Metamorphic rocks are formed from the cooling and solidification of magma or lava, while igneous rocks are formed from existing rocks that are changed by heat and pressure.

• Metamorphic rocks are formed from existing rocks that are changed by heat and pressure, while igneous rocks are formed from the cooling and solidification of magma or lava.

• Metamorphic rocks are formed from the cooling and solidification of magma or lava, while igneous rocks are formed from the erosion and deposition of sediments.

• Metamorphic rocks are formed from the cooling and solidification of magma or lava, while igneous rocks are formed from the evaporation of water.

What are the three states of matter?

• solid, liquid, and gas

• liquid, air, and fire

• solid, gas, and plasma

• hot, cold, and warm

Explain the concept of melting point in relation to states of matter.

• The melting point is the temperature at which a liquid changes into a gas state.

• The melting point is the temperature at which a solid substance changes into a liquid state.

• The melting point is the temperature at which a gas changes into a solid state.

What is an electric circuit?

• A path that electricity follows

• A type of vehicle

• A type of animal

• A type of fruit

What is the role of a switch in an electric circuit?

• To cook food

• To open or close the circuit

• To send emails

• To play music

Explain the concept of conductors and insulators in an electric circuit.

• Conductors and insulators have no effect on the flow of electric current.

• Conductors and insulators are the same thing.

• Conductors prevent the flow of electric current, while insulators allow it.

• Conductors allow the flow of electric current, while insulators do not.
