Fossils
Are evidence of past life, allows
Inferences about the environment
at the time
Fossils
Rocks formed by accumulating sediment.These rocks are soft and crumbly, often have layers and fossils can be found in them
Sedimentary Rocks
fuel that has formed from remains of trees and plants from millions of years ago
fossil fuel
a feature on the Earth's surface that is part of the terrain
Landform
How was coal formed?
comes from energy that was stored in plants that lived hundreds of millions of years ago.
The study of prehistoric life
Paleontology
Happens over time as sediments settle on land or water?
Sediments settle and create layers and cement together over time.
To draw to a close, to finish or conclude with an explanation, ...
conclusion
The outermost layer of the Earth
crust
What are some examples of non-renewable resources?
Oil, coal, and natural gas
Where most fossils are found
Under water
What process best describes why the sedimentary rock changed shape?
Weathering
the process of making inferences or educated guesses about a particular parameter.
hypothesis
where continental plates collide, as they do, for example, in the Asian subcontinent
collision zone
formed from the remains of animals and plants that lived millions of years ago. Over the years, the remains were covered by layers of mud. Heat and pressure from these layers helped the remains turn into
oil
Sand, mud, and little pieces of rock are commonly called
Sediment
Small pebbles, pieces of other rocks, and sand are all examples of ____________ .
sediment
a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition
Physical Weathering
where the edges of the heavier oceanic plate are slowly sinking below continental plates.
subduction zones
use heat from deep inside the Earth to generate steam to make electricity.
Geothermal power
A map that shows what rocks are beneath the surface of the Earth
Geological Map
Four basic processes are involved in the formation of a clastic sedimentary rock:
weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kind
a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
Chemical Weathering
Where continental plates collide, they crunch together and form ________ and cause earthquakes
mountains
sometimes called biomass, is any material made by plants and animals that we can covert into energy.
Biofuels
