Earth in the Solar System

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

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.
