Which of these supports the modern model of the solar system?
The inner planets contain the majority of the solar system mass
Planets move in well defined circular orbits
Planets closer to the sun are more dense than those farther from the sun
Matter is evenly distributed throughout the solar system.
Which of these is based on theoretical calculations, not observations?
Kuiper Belt
Asteroid Belt
Oort Cloud
Pluto
Which of these has been observed in other areas of the galaxy that supports how our solar system formed?
Planets have been see around young stars
Jupiter sized planets have been seen close to stars
Very young stars have been seen surrounded by disks of gas and dust.
Scientist haven't observed any solar systems similar to ours.
Which of these cannot be determined by observing lunar rocks in reference to Earth? (choose two)
estimated age of Earth
bulk composition of the solar system
bulk composition of Earth
formation of planets through accretion of smaller objects
How is orbital velocity related to distance from the sun?
The closer the planet is to the sun, the faster the velocity
The farther away the planet is from the sun, the faster the velocity.
The closer the planet is to the sun, the slower the velocity
There is no correlation between orbital velocity and distance from the sun.
Which answer does not support the heliocentric model?
The sun is stationary with elliptical orbits around it
Mars moves in two directions
Gravitational forces keep planets in orbit around the sun
Determined using telescopes and space probes.
Which of the following statements are true? (Choose 2)
All terrestrial planets are rocky
Most of the planets are made of ice.
The planets rotate in different directions
The planets all orbit with a few degrees of a common plane
Radiometric dating shows the Earth is much younger than Mars.
Which of the following is not true based on the nebular theory?
The solar system began as a nebula, a cloud of dust and gas
Some kind of disturbance caused the cloud to collapse
Due to fusion massive amounts of energy was released sending volatile compounds outward.
The central star formed through accretion.
Why is relying solely on data from Earth surface not reliable to determine the age of the solar system?
The rocks on Earth haven't changed since the formation of the solar system.
The rocks on the moon haven't changed since the formation of the solar system.
Earth has plate tectonics and the rock cycle
The data obtained from rocks on Earth is solely how the age of the solar system was determined.
The following is a list of eccentricities of planets:
Mercury - 0.206
Pluto - 0.25
Venus - 0.007
Jupiter - 0.0.53
Which planet has the most circular orbit?
Mercury
Pluto
Venus
Jupiter
Which factors affect when Earth will have a glacial period. Choose all the correct answers.
Earth's tilt
Earth's eccentricity
Direction of Earth's orbit
Earth's precession
Earth's rotation
Increasing the tilt of Earth would cause which of the following in the northern hemisphere?
Warmer summers and colder winters
Cooler summers and warmer winters
Cooler summers and winters
Warmer summers and winters
If a planet's orbital velocity remains constant, what eccentricity would you expect to see?
eccentricity would be 0, making the orbit elongated oval
eccentricity would be close to 1, making the orbit elongated oval
eccentricity would be close to 1, making the orbit circular
eccentricity would be 0, making the orbit circular
