The image below show a special alignment of the Sun, moon, and Earth. How would this perpendicular configuration affect the tides on Earth?
it produces diurnal tides
produces the least change between high and low tides
produces the greatest change in high and low tides
it produces semidiurnal tides
It is hotter in the summer than in the winter because
the gravity of the Sun and Moon pull on the Earth more in the winter
the Sun is tilted causing rays to arrive at a lower angle
the Sun is lower in the sky and the days are shorter.
the Sun is higher in the sky and the days are longer
Kepler’s First Law states:
the shape of the planets is circular
planets have thick atmospheres
planets orbit the Sun

Solar radiation is important to living things on Earth because
animals use light to break down their food through cellular respiration
Gamma rays are needed to make sure DNA is not mutated
light is needed for water to freeze
plants use light to make their own food through photosynthesis
The length of a year is determined by the amount of time it takes
Earth to revolve around the Sun
the Sun to rotate on its axis.
the Moon to revolve around Earth
Earth to rotate on its axis.
In the diagram below, where in the planet’s orbit would it be moving FASTER?
B at perihelion
A at perihelion
B at aphelion
A at aphelion
A process occurs in a star that converts matter into Energy. Which of these describes the process that includes the conversion of matter into Energy?
Atoms acquire electrons to form negative ions.
Atoms release electrons to form positive ions
Atoms fuse, increasing the average size of atomic nuclei
Atoms split, decreasing the average size of atomic nuclei.
The Moon does NOT orbit the exact center of the Earth. Instead the Moon and the Earth are in orbit around each other. They both orbit the
Precession
Nutation
Ellipse
Barycenter
What is the relationship between area 1 and area 2?
Area 1 is 50% smaller than area 2.
Area 1 is the same size as Area 2.
Area 1 is twice as big as Area 2.
Area 1 is 50% larger than area 2.
Kepler’s third law shown by the equation p2=a3 shows that
Pluto is no longer a planet.
the Moon is drifting closer to the Earth.
meteorites are space dust that impact the Earth.
the further a planet is from the Sun, the longer it takes it to orbit.
What is happening to the size of our universe? (supported by redshift of light from other stars)
collapsing
expanding
not changing at all
shrinking
Many forms of _________________________ _________________ such as radio waves, visible light, and gamma waves are produced by reactions in the Sun.

Coriolis Effect
precessional energy
The amount of gravitational force which applies everywhere in the Universe between objects with mass depends on their ____.
inertia
speed and direction
masses and the distance between them
frictional forces

the known universe began as a ball of dust
What 2 phenomena cause the seasons?
The tilt of the Earth’s axis and the revolution around the Sun
The distance to the Sun and the revolution around the Sun
The tilt of Earth’s axis and the distance to the Sun
The angle of the Sun and the distance to the Sun
What caused the axis of the Earth to be tilted?
an impact with a large object, Theia
the pull of the oceans
the gravity of the Earth to the Moon
the gravity of the Sun to the Earth
The eccentricity of Earth's orbit is about .017 while the eccentricity of Haley's Comet is about .97. This means that:
No conculusions can be drawn from this information.
Earth's orbit is almost a circle, and Haley's Comet's orbit is almost a line.
They both have circular orbits.
Earth's orbit is almost a line, and Haley's comet orbit is almost a circle
The model shows Earth in four different positions in its orbit around the Sun. Which statement correctly explains which position of Earth represents summer in the United States?
The nebular hypothesis states that
the Universe formed from a large explosion.
our Solar System operates under different natural laws than the rest of the Universe.
the Solar System formed from gas and dust orbiting the Sun which clumped up together to form the planets.
The Moon orbits the Sun because of the larger gravity of the Sun.
The terrestrial planets are
the farthest from the Sun
are called the gas giants because they are large and are composed of gases.
include Mercury, Venus, Earth, Mars, and Jupiter
are made of rocks and metals
During an eclipse, the ______________ of the Sun is visible,
and the ____________________ , just beyond the radiative zone, is where gases both rise and sink

The text describes a debate that people are having about the cause of the rise in global temperature. Most scientist believe that global warming is largely caused by the greenhouse gases released by the burning of coal and oil. According to the text, what do other people believe causes global warming?
carbon dioxide
the Sun
methane
radiometers
The graphs at the end of the text show the changes in the number of sunspots, brightness, and global average temperatures from 1880 to 2000.
Based on the evidence, what conclusions can you draw about the relationships between the number of sunspots and the global average temperature?
A decrease in sunspot number causes a decrease in the global average temperature
A decrease in sunspot number causes an increase in global average temperature
The number of sunspots has little to no effect on the global average temperature
The number of sunspots has a direct and powerful effect on the global average temperature
What is the main idea of this text?
In the debate on the cause of the rise in global temperature, evidence suggests that greenhouse gases are the cause of global warming
In the debate on the cause of the rise in global temperature, evidence suggests that greenhouse gases are NOT the cause of global warming
In the debate on the cause of the rise in global temperature, evidence suggests that the Sun is the cause of global warming
In the debate on the cause of the rise in global temperature, evidence suggests that the Sun is NOT the cause of global warming
