Astronomy

Conservation of angular momentum means that a spinning body tends to:

• keep spinning.

• slow down

• wobble into an eccentric orbit

• fly apart

As the solar nebula contracts due to gravitation, the cloud:

• expands

• spins faster

• becomes more spherical in shape

• changes direction

• begins to cool

A meteorite is

• an irregularly shaped body, mostly found orbiting between Mars and Jupiter

• a chunk of space debris that has struck the ground

• a chunk of space debris orbiting the Earth

• a streak of light in the atmosphere.

• an icy body with a long tail extending from it.

The Kuiper Belt is an "outer asteroid belt" consisting of what types of solar system bodies?

• asteroids

• meteroids

• icy cometlike bodies

• jovian planets

• terrestrial planets

The smallest sort of interplanetary matter is called:

• interplanetary dust

• meteoroid

• asteroid

• Kuiper Belt Object

• comet

The difference between a meteoroid and an asteroid is the object's

• shape

• composition

• orbital period

• location in the solar system

• size

In composition and density, the asteroids most resemble:

• pieces of terrestrial planets.

• comets

• the sun

• Jovian planets

• Kuiper Belt objects like Pluto
