What technology is used to measure the energy released from an earthquake?

• Siesmometers

• satellites

• Seismographs

• paw patrol

Which is the BEST comparison of static electricity and electric current?

• Static electricity flows through wires, while electric current jumps across wires

• Static elecctricity involves open circuits, while electric current involves closed circuits

• Static electricity involves the build-up of electrons in an object, while electric current involves the flow of electrons through wires

• Static electricity begins with objects that have a negative charge, while electric current begins with objects that have a positive charge.

A student carries out an investigation to observe a change of state in water. She records her observations and data in the diagram above. Which argument is supported by the student's observations?

• A decrease in temperature makes water change from a liquid to a solid

• A decrease in temperature makes water change from a solid to a liquid

• An increase in temperature makes water change from a liquid to a solid

• An increase in temperature makes water change from a solid to a liquid
