they use major fossil records
What else can I help you with?
Where does most geologic activity take place on Earth?
Most geologic activity on Earth takes place along tectonic plate boundaries, where plates move and interact, leading to events like earthquakes, volcanic eruptions, and mountain building.
Is there evidence of past life on mars?
Scientist have found what looks to be a place were there was once water so there is a big possibility.
Do many geologic processes and events happen because of erosion?
Erosion is one of several key geologic processes that shape the Earth's surface. It can lead to the formation of valleys, canyons, and other landforms by wearing away rocks and moving sediment from one place to another. Erosion can also trigger other geologic events, such as landslides and soil erosion, which can have significant impacts on landscapes and ecosystems.
What geologic events would have to take place for a chain of composite volcanoes to form along the east coasts of the United States and Canada?
About 2 - 3 weeks
What is a important characteristic of a index fossil?
to place events on the geologic time scale
How do you know that the events of the eruption in Pompeii took place?
there's plenty of archaelogical evidence as well as written historical sources.
What does factual events mean?
Factual events refer to real occurrences that have taken place and can be verified through credible sources or evidence. These events are based on actual happenings rather than opinions, speculations, or fiction.
As the plates continue to grind against each otherwhat other geologic event could take place?
As the plates grind against each other, it can lead to earthquakes, volcanic eruptions, and the formation of mountain ranges. The friction between the plates can cause stress to build up until it is released suddenly, resulting in these geologic events.
A place where two geologic units meet is called?
A contact or boundary.
What kind of changes mark the beginning and ending of divisions in geologic time?
Earth's past has been organized into various units according to events which took place in each period. I got my info from Wikipedia you can look there for more info.
What questions can be asked to lay a solid foundation for evidence in the case?
To lay a solid foundation for evidence in a case, one can ask questions such as: What specific events or actions occurred? Who was present or involved? When and where did the events take place? Are there any documents or physical evidence related to the case? Can witnesses provide testimony to support the claims? What motives or intentions might be relevant to the case? Are there any inconsistencies or gaps in the evidence that need to be addressed?
What evidence do scientists use to place events on this time line?
Scientists use various types of evidence to place events on a timeline, including radiometric dating techniques to determine the age of rocks and fossils. Stratigraphy, or the study of rock layers, helps establish the relative timing of events based on the sequence of sediment deposition. Fossil records provide insights into the evolution and extinction of species over time. Additionally, historical records and geological evidence, such as volcanic activity or ice core samples, contribute to a more comprehensive understanding of Earth's timeline.
