Inside Earth
Remains, impressions, tracks, or other evidence of ancient organisms that are preserved in sedimentary rocks.
What are fossils?
The process by which natural forces break down rocks.
What is weathering?
Resources, such as water and trees, that can be replaced by natural processes in 100 years or less.
What are renewable resources?
The center of the Earth.
What is the inner core?
Layers of rock.
What is strata?
The breakdown or decomposition of rock that takes place when minerals change through chemical processes.
What is chemical weathering?
Coal, oil and natural gas made from the remains of microscopic organisms or ancient plants that lived on Earth millions of years ago. Used to produce energy and contributes to global warming.
What are fossil fuels?
What are dinosaurs?
A naturally occurring material that is broken down by processes of weathering and erosion.
What is sediment?
The most abundant greenhouse gas in the atmopshere.
What is Carbon Dioxide?
Large pieces of the crust that move around on the Earth's surface and 'float' above the mantle.
What are tectonic plates?
The branch of science concerned with the fossil remains of plants and animals.
What is paleontology?
The breakdown of rock into smaller pieces of the same material without any change in its composition.
What mechanical weathering?
Rocks whose structure, composition, and texture have changed from those of the parent rock.
What are metamorphic rocks?
A renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.
What is hydropower?
A historical sequence of life on Earth, documented by the preserved remains or traces of organisms found in sedimentary rock.
What is the fossil record?
A geologic feature in the Southwestern U.S. that was formed through a combination of geological uplift, river erosion, and other erosional processes over millions of years. Home to the Colorado river.
What is the Grand Canyon?
When a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers.
What is habitat destruction?
