left behind a sea over Indiana. As that sea
evaporated the particles from the living
substances settled to the ground and reacted
chemically to each other and the water to
form chemical sedimentary rocks.

worn away and transported from one place to
another by a natural agent, such as wind,
water, ice, or gravity

pieces
• Chemical Weathering: Chemical alteration of
minerals, changes both the composition and
physical appearance of the rock.

water vapor into the atmosphere

the divergent plate boundaries which causes
sea-floor spreading. The Pacific ocean is
shrinking because it has convergent plate
boundaries with subduction.

of rock are on the bottom while the newer
layers are at the top.
• Cross-cutting relationships says that the rock
cutting through layers of rock must be
younger than the layers it’s cutting across.
• Oldest: Q, O, N, M, L, P, H, I, J, K: Youngest

dry places, because most bacteria which cause
decay cannot survive in these places.

groundwater replace the original organic
materials that were covered by layers of
sediment with new materials.

use over and over again (ex. Wind, solar).
Nonrenewable is a source that you can only
use once (ex. Oil, natural gas)
Chapter 24.2
• Carbon Cycle: Carbon dioxide is absorbed
when plants are undergoing photosynthesis,
oxygen is released as a by product. Plants also
form carbohydrates which is consumed by
animals and is the basis for life. Other
organisms release carbon dioxide into the
atmosphere during respiration. The cycle
starts all over again.
Chapter 24.2
• Nitrogen Cycle: Nitrogen is an element used
by organisms to produce proteins. Nitrogen
fixing bacteria have to convert nitrogen from
the atmosphere to be used by organisms to
produce proteins. This cycle continues as
animals eat one another and as waste is
excreted by animals.
