What else can I help you with?
How will a scientist make a geologic column of rock layers from different parts of the state?
help
What kind of scientist worked with geologist to develop the geologic scale?
biologists
What do a modern day scientist believe about geologic change?
Some happens gradually, and some happens suddenly
What evidence do scientist use to place events on the geologic time scale?
they use major fossil records
What did scientist use when geologic timescale?
Scientists use various methods such as radiometric dating, fossil evidence, stratigraphy, and biological markers to establish and categorize the different time divisions on the geologic time scale. These methods help in determining the age of rocks and fossils, as well as understanding the sequence of events that have occurred throughout Earth's history.
What scientist studies rocks and geologic processes of ocean basins?
A scientist who studies rocks and geologic processes in ocean basins is a marine geologist. They investigate the formation and evolution of the ocean floor, as well as the geological features and processes that shape ocean basins. Their research contributes to our understanding of plate tectonics, seafloor spreading, and marine geology.
What types of evidence do scientist use in dividing geologic time into smaller time segments?
Iron precipitation is a chemical formula that scientists use in dividing geologic time into smaller time segments. They also use C14 dating to determine this.
The four types of geologic contacts traditionally shown on geologic maps?
The four types of geologic contacts shown on geologic maps are faults, igneous intrusions, unconformities, and sedimentary contacts. These contacts represent boundaries between different rock units with distinct characteristics and histories. Geologists use these contacts to understand the geologic history of an area and to interpret the relationships between different rock formations.
What do scientists need know about geologic formations to make a geologic map?
To have a scientist make a geologic map, they need to know something about geologic formation to show what the map is meaning. They use color to show the differences of the kind of rock and its age.
How are geologic units of similar ages shown on a geologic map?
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
What is the best evidence that many different geologic periods are represented in Virginia?
The presence of fossils of different ages
Which of the following is not a geologic period of the Earth Jurassic Cretaceous Triassic Neoprene?
Neoprene is not a geologic period of the Earth. The Jurassic, Cretaceous, and Triassic are all recognized geologic periods that represent different intervals of time in the Earth's history.
