A scientist hiking in a desert observes a cliff. The scientist makes a drawing of the layers of rock in the cliff and the types of fossils observed in the layers. Based on observations, the scientist determines layers 3 and 5 were formed from cooled lava. The scientist's drawing is shown above.

Identify the oldest layer in the rock cliff and explain your reasoning for the layer chosen.

Day and night are the result of the earth's rotation on its own axis and its location from the sun. As the earth spins on its axis, parts of the planet are in the sun while others are in the dark. In other words, the sun appears to rise and set. The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day.

What fractions of the earth are in day and night at any time?

• Depends on the season

• 1/4 in day and 3/4 in night

• Depends on the tilt of the Earth

• 1/2 in the day and 1/2 in the night

Magnetic fields are produced by the motion of electrical charges. The motion of negatively charged electrons create the magnetic field in a bar magnet. The origin of the Earth's magnetic field is not completely understood. It is thought to be associated with electrical currents produced from the coupling convective effects and rotation of the spinning outer core of metallic liquid made of iron and nickel.

What does the Earth's magnetic field shield Earth from?

• meteors

• asteroids

• solar wind

• ozone depletion

Which of these is MOST LIKELY to cause natural pollution?

• a drought

• an avalanche

• heavy snow

• volcanic activity
