2. METEOROIDS
• They are interplanetary,metallic,and stony celestial bodies that vary
from a fraction of a millimeter to a few hundred meters.
• They are also called meteors, or shooting stars, when they enter earths
atmosphere.
• It becomes luminous because of the vast amount of heat generated by
friction with air. Most meteoroids vaporize in the atmosphere, but
some bigger ones survive the travel through the atmosphere and strike
the surface of the earth, in which they are called meteorites.

3. IMPACT CRATER
• Some meteorites hold enough mass
to create a depression on the Earths
crust.

4. TYPES OF METEORITES BASE ON THEIR
COMPOSITION
1. Less common – iron–nickel type with a higher density.
2. Most common – stony in nature, made up of silicates with some
iron and nickel.
3. Classified as stony iron – consists of stone material, iron, and
nickel.
