(1) 3 a.m.
(2) 6 a.m.
(3) 6 p.m.
(4) 9 p.m.
14. Most of Earth’s major earthquakes are caused by
(1) seasonal heating and cooling of Earth’s surface
(2) weathering of rock at Earth’s surface
(3) Earth’s gravitational attraction to the Moon
(4) faulting of rock in Earth’s crust
15. Weathering and erosion of Earth’s crust are primarily caused by
(1) gravity
(3) evaporation
(2) volcanic activity

II. Answer all questions in this part using your knowledge in science and the scientific method.
Base your answers to questions 23 through 26 on the information below and on your knowledge of science.
A student determined that shaking a container of sand caused the temperature of the
sand to rise. The student then performed a new experiment to see if shaking a container of pebbles
would cause the temperature of the pebbles to rise.
23. Explain why the shaking caused the temperature of the sand to rise. [1]
