Which is not one of Earth's layers?
D. ocean
Maria is building a model to show the location of all water on Earth. Which two spheres contain most of Earth's water?
A. hydrosphere and cryosphere
C. The balloon rises because convection causes the warmer air inside the balloon to rise in the cool atmosphere
How does deposition change the Earth's surface?
Wind deposits build up sand dunes. Water deposits create barrier islands, deltas, etc.
Which method do scientists use to find the relative ages of rock samples?
F. law of superposition
Which layer extends from below the mantle to the center of the Earth?
F. core
Which layer of the atmosphere does weather occur?
I. troposphere
Jermaine described how he saw steam rise from a puddle after the sun came out. Which processes did he observe?
H. radiation and convection
How are sediments created?
Weathering causes sediments by breaking down rock into smaller pieces
Which represents the youngest layer of rock?
A. Layer 1
Javier is going to construct a physical model of Earth. What is the correct order, from inside to outside, of Earth's layers?
C. inner core, outer core, mesosphere, asthenosphere, and lithosphere
How can ocean currents affect local weather?
D. Ocean currents can affect air temperature
One morning before the sun rose, Cole noticed it was very warm outside. Later that day, Cole noticed it became colder. Which statement best explains why it became colder as the day went on?
D. energy from the sun causes the atmosphere to move continuously
What is the difference between weathering and erosion?
Weathering is the breaking down of rock and erosion is the movement of rock.
How can scientists use carbon 14 to determine the age of a rock?
I. The proportion of carbon 14 in the rock tells how old it is

How do sediments make new landforms?
Sediment is carried by water, ice, wind, or gravity by erosion and deposited over time.
A rock formation near Gainesville, FL was formed 530 million years ago. Which information does a scientist need to most accurately determine the age of a rock?
C. The amount of each radioactive element present in the rock
Which is not explained by plate tectonics?
B. floods
What does warm water carried by the Gulf Stream to the North Atlantic Ocean cause?
D. a mild climate for the coast of Florida
People harness the sun's energy in many ways. Which is not a result of the sun's energy?
