Concept #7 Quiz
Choose the best possible answer to the following questions about Key Concept 7 "Development and evolution of the solar system and the Earth."

This activity contains 7 questions.

	Which observation below makes the universe a feasible outcome of the Big Bang?   The universe is currently exploding, illustrated by shifts on space images in the visible light spectrum. We just know this as a fact. The universe is currently contracting toward a point area, illustrated by light shifts in space images. The universe is currently expanding away from a point area, illustrated by light shifts in space images.

	Currently, the nebular theory is the accepted model to explain the formation of our solar system. All of the following statements support this idea except _______.   the planetary system is disc-shaped in total all planets (except Pluto) orbit the Sun in the same plane the Sun is at the center of a disc-like planetary system the planets orbit each other as they orbit the Sun

	In our solar system today, the inner four planets are not gas-ice giants like the outer ones. Why?   The solar system dust from the nebula were expelled due to gravity of the sun, whereas gases were contracted. The solar system gas from the nebula contracted due to gravity of the sun, whereas dust was expelled. The solar system dust from the nebula contracted due to gravity of the sun, whereas gases were expelled. None of these.

	Label the sequence of events describing the nebular origin of the solar system. For each item below, use the pull-down menu to select the letter that labels the correct part of the image. 4.1 Cooling of the nebula causes condensation of dust into solid particles. A B C D 4.2 Accretion of planets. A B C D 4.3 Contraction of the nebula into a rotating disk. A B C D 4.4 The early solar system is a dust and gas cloud (nebula). A B C D

	The Earth is today divided into three basic concentric spherical shells. What is the process by which this "shell" configuration emerged. What caused it to happen?   concretion / inertia differentiation / inertia differentiation / gravity concretion / gravity

	Each of the following statements about the early formation of the Earth is true except ________.   High velocity impacts caused the temperature to increase and iron and nickel to sink to the center. Chemical differentiation established the three basic shells of Earth's interior. The primitive core and crust melted to form the early Earth's mantle and hydrosphere. A primitive atmosphere evolved as gaseous materials escaped from Earth's interior. Buoyant masses of molten rock rose to the surface to produce a primitive crust.

	Relative dating involves __________.   placing events in their proper sequence or order without knowing their numerical ages in years using the law of superposition to compare the ages of rock layers comparing fossils found in rock layers all of the above none of the above
