What process has occurred when atoms combine to form a new element and release energy?

• Hydrogenation
• Fission
• Ionization

Slate is a fairly common rock that can be used for roofing shingles. What property makes it MOST suitable for this use?

• It feels soft and smooth.
• It can occur in different colors.
• It is hard and brittle.
• It can be split into thin, flat layers.

Rock layers tell a story about their past. What is the basic assumption that is made when reading this story?

• Chemical reactions in the past were slower than they are today.
• The Earth's crust cooled and then remelted
  before rock layers began to form.
• The processes in the rock cycle were the same
  in the past as they are today.
• The composition of the Earth's atmosphere
  has been constant.

The Earth's mantle is made up of very hot material that rises to the top of the mantle, cools, then sinks, reheats, and rises again, constantly repeating the cycle. This action, which causes the Earth's crust to move, is known as -

• Hot spots
• Advection Forces
• Magnetic field
• Convection Currents

Which of the following minerals found in the northern Piedmont province is known as "fool's gold"?

• Galena
• Pyrite

• Hematite

Saturn's volume is 762 times the volume of Earth, and yet its mass is only about 95 times that of Earth's mass. That is due to Saturn's -

• Low Density
• Distance from the Sun
• Thousands of rings
• tempurature

The highest and lowest tides are known as spring tides. When do these tides occur? 

• During the new moon and cresent moon phase
• Between the half moon and full moon phases
• Between the new moon and full moon phases
• Between the full moon and cresent moon phases

The moon has a stronger influence on Earth's tides than the sun because the moon -

• Moves much faster relative to Earth
• Is much closer to Earth
• Is denser than the sun
• Has more mass than the sun

Remains of ancient life are most often preserved through which process?

• Freezing
• Entrapment in tar
• Burial in Sediment
• Drying out
