What is a scientific theory?

• a repeating pattern in a scientific model

• a truth that is universally acknowledged by scientists

• a well-tested explanation of scientific observations and experiments

• a guess that is made early in an investigation based on available information

Which of these is a pattern that scientists can use to study the formation of the solar system?

• Earth’s weather patterns for the last 5 years

• Jupiter’s surface temperatures for the past 10 years

• the revolution of the planets over the last 100 years

Which of these is NOT true of the patterns of the planets’ orbits?

• Their orbits do not cross.

• The sun is near the center of each orbit.

• They are ellipses that are nearly circular in shape.

• The distance between any two orbits changes based on how fast the planets rotate.

A nebula is a

• collection of comets.

• large cloud of gas and dust.

• collection of dwarf planets.

• large constellation of stars.

What is the Nebular Theory?

• a theory that explains how solar systems form

• a theory that explains why there is life on Earth

• a theory that explains what causes a supernova

• a theory that explains the shape of the universe

What happens during a supernova?

• two nebulas collide

• a massive star explodes

• a new solar system forms

• a sun emits a small burst of energy

What role do scientists believe a supernova played in the Nebular Theory?

• The supernova merged with the nebula and created several solar systems.

• . The supernova pushed matter together, causing matter in the nebula to expand.

• The supernova pulled matter apart, causing matter in the nebula to break apart and flatten

• The supernova pushed matter together in a nebula, causing the matter to rotate and flatten.

How did the bits of dust and gas that eventually formed the solar system behave while falling into orbit around each other?

• They collided and went spiraling in opposite directions.

• They expanded as they were pulled farther apart and eventually cooled.

• They created new gases that caused them to cool after interacting with each other.

• They ran into each other and stuck together due to gravitational and other forces.
