Definitions 1
breaking down of rocks and minerals on Earth's surface
What is weathering?
What is strata?
A person who studies plant's structure.
Who is a geologist?
Strata are stacked, vertical layers of sedimentary rock or soil formed over millions of years.
false, horizontal
geo
earth
any foreign piece of material that becomes trapped inside a host rock or mineral as it forms.
What is inclusion
What is index fossil?
The scientific study of the earth.
What is geology?
Absolute age describes the age of an object, event, or person in comparison.
False, relative age
paleo
ancient / old
The total collection of discovered fossils and their placement within Earth's layers.
What is a fossil record?
A break in the earth's crust where the rock on either side has moved or shifted
What is a fault?
a foreign piece of material such as a mineral, crystal, a water droplet, gas bubble, or a fragment of older rock
What is an inclusion
The geological feature is any physical structure or part of the Earth's surface or subsurface.
True
lith
rock
The process by which natural forces like wind, water, or ice wear away soil ad rock and move those materials to a new location.
States that in any undisturbed sequence of rock layers the oldest layer is at the top and the youngest is at the bottom.
What is the Law of Superposition?
A rare, geological event where more than half of all plant and animal species on Earth die out in a relatively short period of time.
What is mass extinction?
The principle of cross-cutting relationships states that any geological feature that cuts across or breaks another must be older than the feature it disrupts.
False, it must be younger
chrono
time
A missing gap in the geologic record.
What is unconformity?
A body of molten magma that pushes its way into pre-existing rock layers deep underground, where it then cools and solidifies.
What is intrusion?
matching up rock layers OR fossils found in different geographic locations to prove they are the same age or part of the same original formation.
What is correlation?
A paleontologist is a person who studies the plant's structure.
false, geologist
archaeo
ancient / beginning
