Asked by final exam please
                15.  How does convection transfer heat throughout Earth’s surface and interior?  (1 point)
Heat and pressure build up over time in the Earth’s core.
Heat cycles through liquid magma currents in the mantle.
Heat from the sun reaches Earth in the form of rays and waves.
Heat moves between materials in direct contact with each other.
16. Which wave property can be measured as crest-to-crest or trough-to-trough? (1 point)
amplitude
frequency
wavelength
wave speed
17. Which of the following correctly describes a property of a sound wave but not a property of an electromagnetic wave? (1 point)
transfers energy
requires a medium
swings back and forth while traveling
travels the same speed in any medium
