Which of the following statements explains the formation of
tides?
• A. Earth rotates faster than the water in the oceans and the
water’s inertia causes it to move around the planet. This
causes tides.
• B. The Sun’s uneven heating of Earth’s surface and oceans
causes wind and ocean currents. Combinations of these
currents cause tides.
• C. The gravity of the Moon and Sun pull on the water of the
oceans and cause it to bulge. This, combined with the rotation
of Earth, causes tides.
• D. Magnetic and gravitational fields affect the water in the
oceans, causing it to move in a large cycle synchronized with
magma movement beneath Earth. This causes tides.
Which of the following statements explains the
formation of tides?
• C. The gravity of the Moon and Sun pull on the
water of the oceans and cause it to bulge. This,
combined with the rotation of Earth, causes
tides.
• The energy from tides can be used to produce
electricity. Ocean tides are caused by
gravitational pull on the oceans from both the
moon and the sun. The greater tidal pull comes
from the
• A. sun because it is closer to Earth than the moon
• B. moon because it is closer to Earth than the sun
• C. sun because it is farther from Earth than the
moon
• D. moon because it is farther from Earth than the
sun
• The energy from tides can be used to produce
electricity. Ocean tides are caused by
gravitational pull on the oceans from both the
moon and the sun. The greater tidal pull
comes from the
• B. moon because it is closer to Earth than the
sun

B. DC to thermal energy
C. AC to chemical energy
D. DC to chemical energy
• Photovoltaic cells produce electrical energy
that can be stored in batteries. This process of
