Fossils of Glossopteris have been found on Antarctica, proving:

Antarctica was once closer to the Equator

Swells become breaking waves because:

Their top moves faster than their bottom

What principle states that a fault is younger than the rock layer that it cuts through?

Principle of cross-cutting relationships

A fossil is thought to be a thousand years old. The fossil has:

More than half of its original amount of carbon-14 left

A breakwater works to slow beach erosion because:

It causes waves to break early and lose energy

If a dinosaur bone is found in a rock layer:

The bone and the rock are similar in age

One plate will subduct underneath another only if:

The subducting plate is more dense than the overriding plate

Pushes more on Earth's surface because it is sinking

Questions 21

Answers

1
The Gulf Stream is:
A freshwater current
A cold surface current
A warm surface current
An unusually low tide
2
If a bone contains only 1/8 of its original amount of carbon-14:
It is 17,190 years old
It is 5,730 years old
It is 5 million years old
It is not old
3
Fossils of Glossopteris have been found on Antarctica, proving:
Antarctica was part of Pangaea
Antarctica was once closer to the Equator
Antarctica is cold
Antarctica was once closer to the South Pole
4
A feature of Earth's surface formed by oceanic-oceanic convergence is:
The Peru-Chile Trench
The Red Sea
The Aleutian Islands
The Himalayas
5
An example of an imprint fossil would be:
An insect preserved in sap
A footprint
None of these
A bone fragment
6
What type of plate boundary is the Mid Atlantic Ridge?
None of the above
Convergent
Divergent
Transform Fault
7
You feel hot on a humid day because:
Your sweat won't evaporate
Water vapor condenses on your skin
Air pressure is high
You sweat
8
Swells become breaking waves because:
None of these are correct
Their top is slowed by friction
They get too tall to support themselves
Their top moves faster than their bottom
9
Convection happens because:
Dense material sinks
Temperature affects density
Materials of low density rise
These are all true
10
A falling barometer tells you:
That the pressure is dropping
All are true
That rain is coming
That a storm may be approaching
11
A fossil only forms in which family of rock?
Igneous
Sedimentary
Led Zeppelin
Metamorphic
12
A sling psychrometer works because:
Evaporation causes cooling
Water is cooler than air
It can sense the presence of water vapor
All of these are true
13
What principle states that a fault is younger than the rock layer that it cuts through?
None of these
Principle of superposition
Principle of cross-cutting relationships
Principal of WHS
14
A fossil is thought to be a thousand years old. The fossil has:
Less than half of its original carbon-14 left
Less than 1/4 of its original amount of carbon-14 left
Lost all of its original carbon-14
More than half of its original amount of carbon-14 left
15
Clouds can only form if:
Air cools to dew point
Condensation occurs
All of these are true
Relative humidity hits 100%
16
Increasing which of these things will increase the size of waves?
All are correct
Wind duration
Fetch
Wind speed
17
A breakwater works to slow beach erosion because:
It stops whales from splashing the beach with their tails
It blocks longshore currents
It adds fetch to a body of water
It causes waves to break early and lose energy
18
If a dinosaur bone is found in a rock layer:
The bone and the rock are similar in age
The rock killed the dinosaur
The bone becomes inorganic
The fossil is older than the rock
19
One plate will subduct underneath another only if:
The subducting plate is more dense than the overriding plate
They are divergent
The subducting plate is less dense than the overriding plate
They are transform
20
Cold air:
Pushes more on Earth's surface because it is sinking
Pushes less on Earth's surface because it is rising
Usually holds a high amount of humidity
Pushes more on Earth's surface because it is rising
21
Which air mass is the closest to saturation?
Really dry air
93% relative humidity
60% relative humidity
12% relative humidity
