- Chunks of rocks
come in many sizes and shapes, from boulders to grains of sand and even
smaller.
- Earth materials
include rocks (including minerals) and soil.
- The earth,
made of rocks (and minerals), has many shapes.
- Soils have the
properties of color and texture, the capacity to retain water, and the
ability to support the growth of many kinds of plants, including those
used for human consumption.
- Rock is composed
of different combinations of minerals. Smaller rocks come from the breakage
and weathering of bedrock and larger rocks. Soil is made partly from
weathered rock and partly from plant remains and also contains many
living organisms.
- Most rocks are
made of several substances (minerals), but some rocks are made of one
substance (minerals).
- The surface of
the earth changes. Some changes are due to slow processes such as erosion
and weathering, and some changes are due to rapid processes such as
landslides, volcanic eruptions, and earthquakes.
- Rocks are found
in layers formed over a long period of time.
- All rocks break
apart and form new rocks (rock cycle).
