explain how the universe was formed
small piece of matter blew up and expanded to create all of the solar systems in the universe.
events in nature that may have a negative effect
major geological event that occurs when plates shift suddenly and release stored energy; a frequent occurence along all types of plate boundaries
catastrophic events
earthquake
list 2 examples of chemical weathering

acid rain, rust
wind, flowing water, glaciers, and gravity
places the sun at the center of our solar system
rocky object moving through space in between the planets; smaller than an asteroid
heliocentric model
meteoroid
Attraction between two objects with a strength that is proportional to the masses of the objects; the force that attracts one object with mass to another
clouds of dust and gas that scientists theorize are how the planets were formed
gravity
nebula
waves of energy that travel through Earth and are the result of an earthquake, volcano, or explosion

seismic waves
climate
a product of photosynthesis; breathed in by humans and animals
breathed out by humans; brought in by plants to be used during photosynthesis
oxygen
carbon dioxide
rocky object that survives passage through the atmosphere but usually burns up before hitting the surface
rocky object that survives passage through the atmosphere and hits Earth's surface
meteor
meteorite
large grouping of stars in space
the most widely accepted theory to explain the origin of the universe; began as a small point that expanded rapidly
galaxy

breaking down of rocks into smaller pieces through physical processes
when particles stop moving and settle where the agents have carried them
weathering
deposition

comet
travels at a constant rate of about 300,000 km/s
how old is the universe?
speed of light
about 13.7 billion years old

made up of all water and ice
geosphere
hydrosphere
