A Student Proposes That Sugar Will Dissolve Faster in Rubbing Alcohol Than
The Student Reasons That Sugar and Rubbing Alcohol Both Contain Carbon
in Water.
So They

Tectonics?answers
( ) Plate Tectonics Explained Observations About Earth
That the Earth Idea Could Not

Explain.
, Astronomers have long accepted that plate tectonics exists nowhere in our
except on Earth. In 2011, a scientist analyzed 100 NASA-space-mission
solar system
photographs
Valles Marineris of on Mars, the longest known series of canyons in the solar
system. The
scientist found that Valles Marineris showed features found only in
locations
where on Earth
major tectonic plates divide. ( Correct answers ) Carry out further
research
gain moretounderstanding of possible plate tectonics
on Mars
According to the theory of plate tectonics, volcanoes are especially likely to
form along
plate boundaries because of rising magma. New satellite data mapping the
ocean floor
reveals thousands of seamounts, which are small volcanoes. Some of the
seamounts
are in lines that could correspond to past or present plate boundaries, but
many are
aligned in not
this way. ( Correct answers ) Carry out more research to
understand
how better
the seamounts
form
For many decades, scientists thought they understood how ozone breaks
down in the creating ozone holes. However, new data show
stratosphere,
significantly
reaction rates lower
than can be explained by the long-held model. ( Correct
Conduct
answers )additional experiments to confirm the
new data
For almost 1500 years most scientists in Europe accepted Ptolemy's
geocentric
planetary model that suggested the sun revolved around Earth. By the
century, most scientists supported a heliocentric model that suggests
eighteenth

A woman does pushups by lowering her body to the floor using her
arms andagainst
pressing then the floor with her hands to push herself back up. ( Correct
answers
The upward) force that the ground exerts on the
woman
Two boxes sitting on the floor look identical, but one has more mass than
the other.
Correct (
answers ) The box with less mass
accelerates more.
Two identical train engines are parked on parallel tracks. One engine
has ten cars
attached, and the other has no cars attached. Each engine exerts the
same net
which force,
allows the train to overcome static friction. ( Correct answers ) The
engine any
pulling not cars will accelerate
more.
A woman applies an upward force to a basket filled with groceries.
Assume she

move up.
A heavy truck and a light car travel at the same velocity side-by-side on
the highway.
Both drivers apply the same braking force at the same moment. ( Correct
