NO.41 Which action demonstrates a physical change?

Baking cookies

Chopping wood

Iron rusting

Milk becoming sour

NO.42 In 1996, NASA scientists claimed that a Martian meteor contained chemical compounds that indicated life on Mars 3.6 billion years ago. However, further studies showed that the same chemical compounds were found in rocks from the Moon, where no life ever existed.
What is the appropriate scientific approach for dealing with this contradiction?

Accept the idea that there has been life on Mars because the scientists worked for NASA

Determine that the chemical compounds that were found do not necessarily indicate life

Decide that life could never have existed on Mars because the chemicals are also found on the Moon

Conclude that there must have been life on the Moon at some time in the past

NO.43 Which process is responsible for the formation of the sand dune pictured above?

Deposition by flowing water

Physical weathering

Deposition by wind

Chemical weathering

NO.44 What energy conversion takes place when a ball rolls up a ramp?

Kinetic energy is converted into gravitational potential energy.

Gravitational potential energy is converted into kinetic energy.

Chemical potential energy is converted into gravitational potential energy.

Elastic potential energy is converted into thermal energy.

NO.45 Which layer of the atmosphere would an atmospheric scientist be investigating if the scientist were studying the formation of clouds?

Stratosphere

Mesosphere

Thermosphere

Troposphere

NO.46 While listening to the morning weather report, a scientist hears that a low pressure system is settling over the area.
How should the scientist prepare for the day’s weather?

Bring extra water and prepare for very hot, humid weather.

Wear warm clothes and bring sunglasses to prepare for cold, sunny weather.

Dress in lightweight clothing and apply a lot of sunscreen to prepare for hot, sunny weather.

Bring an umbrella and wear waterproof shoes to prepare for cloudy, rainy weather.

NO.47 Which type of wave can travel through a vacuum?

Radio waves

Water waves

Seismic waves

Sound waves

NO.48 A team of scientists uses the Hubble Space Telescope to search for evidence of planets orbiting distant stars.
Which kind of investigation are they carrying out?

Laboratory experiment

Constructing a model

Controlled experiment

Observational study

NO.49 Which point In the diagram represents Earth’s location when locations in the southern hemisphere receive the most direct sunlight?

NO.50 In space, small particles of matter can join together to form larger particles. Those larger particles have more mass and can then attract even more particles to themselves to grow even larger. Eventually, they may form an asteroid, comet, planet, or star.
Which force allows the particles to attract more and more particles as their mass increases?

Gravitational

Electrical

Frictional

Magnetic

NO.51 Ball 1 is moving and ball 2 is still. Both balls have the same mass.
What happens to the motion of the two balls if ball 1 strikes ball 2 head on in an elastic collision?

Ball 1 stops, and ball 2 moves at the velocity ball 1 had before the collision.

Ball 1 and ball 2 both move in the direction that ball 1 was initially moving, but ball 1 moves twice as fast.

Ball 1 and ball 2 both move in the direction that ball 1 was initially moving, but ball 2 moves twice as fast.

Ball 2 remains at rest, and ball 1 moves at twice its original velocity.

NO.52 Which of these is an example of climate change caused by human activity?

Weather changes from regularly repeating atmospheric conditions such as El Nino

Worldwide weather changes from changes in the flow of air currents

Year to year differences in snowfall in a given area from different weather patterns

Warming because of farming and fuel use adding nitrous oxide to the atmosphere

NO.53 Which type of wave travels faster through water than through air?

Visible light waves

Sound waves

Radio waves

Gamma waves

NO.54 In which state of matter do particles within a substance vibrate around fixed positions?

Liquid

Solid

Gas

Plasma

NO.55 A group of scientists perform an experiment involving the interaction of protons colliding at high energies.
The results of their experiment contradict current theories regarding these proton interactions.
What is the appropriate response in light of the results of this experiment?

The current theory should be modified to match the findings of this experiment.

The results of this experiment should be discarded.

Other experiments should be done to confirm the findings of this experiment.

The scientists should change the results of their experiment to be consistent with current theories.

NO.56 Kepler discovered that planets move in elliptical paths around the sun. Repeated observations have confirmed Kepler’s finding.
Which type of scientific statement is Kepler’s discovery?

Inference

Theory

Law

Hypothesis

NO.57 The rock layers shown in the illustration have not been disturbed or overturned

Basalt (Igneous)
Sandstone (Sedimentary)
Siltstone (Sedimentary)
Slate (Metamorphic)

It experienced high heat and pressure, followed by deposition and then a volcanic eruption.

It has experienced high heat and pressure throughout its history

It was a desert environment, followed by glaciers and then high heat and pressure

It experienced a volcanic eruption and then was located underwater

NO.58 The island of Iceland is located at a divergent plate boundary. At this boundary, the North American plate and the Eurasian plate are moving apart.
What is expected about natural hazards in Iceland, based on its tectonic setting?

There is high risk of volcanism and low risk of large earthquakes.

There is high risk of large earthquakes and low risk of volcanism.

There is high risk of both volcanism and earthquakes.

There is low risk of both volcanism and earthquakes.
