What is the index fossil of the Cambrian?
Trilobites are one of the index fossils commonly found in Cambrian rock layers. These ancient arthropods lived in the seas during the Cambrian period and are used by geologists as markers for dating rocks from that time period.
How do geologists use index fossils to determine rock age?
Oh, dude, so like, geologists use index fossils to figure out the age of rocks by looking at the specific types of fossils found in them. These fossils are like rock stars of the dating world because they only lived during certain time periods, helping geologists match up the rock layers with a specific era. It's like finding a vintage concert t-shirt in a thrift store and knowing it's from the '80s because of the band on it. So, yeah, index fossils are like the ultimate timekeepers for rocks.
How did Sir Humphry Davy know potassium was an element?
Potassium was discovered in 1807 by Humphry Davy, who derived it from caustic potash (KOH).It is reasonable to think that at that time he worked in London at the Royal Institution, though he might have lived in his hometown of Penzance, Cornwall[I've digged that out of the following incomplete citations from en.wikipedia]"Davy wrote to Davies Giddy on March 8, 1801 about the offers made by Banks and Thompson, a possible move to London and the promise of funding for Davy's work in galvanism.""By June 1802, after just over a year at the Institution and at the age of 23, Davy was nominated to full lecturer at the Royal Institution of Great Britain. In November 1804 Davy became a Fellow of the Royal Society, over which he would later preside"
What did the geologists Charles Lyell propose with respect to the earth?
Charles Lyell proposed the theory of Uniformitarianism, which suggests that the Earth's landscape is a result of slow and continuous geological processes that have been occurring over a long period of time. This theory challenged the prevailing idea of Catastrophism, which posited that the Earth's features were formed by sudden, short-lived events.
What kind of environment did the Anishinabe live in?
The Anishinabe primarily lived in the woodlands and forests of present-day Canada and northern United States. These environments provided them with access to resources like fish, game, and plants for sustenance and materials for crafting. The land was central to their cultural, spiritual, and economic practices.
How many Jewish people lived in them?
50000 billion
How many people lived in Londinium by the year 400?
50000
How can geologists tell about plants and animals that lived on earth a long time ago?
Well, most of the time geologists find fossils of plants and animals, and then study them to find out how long ago the plant(or animal) lived.
How many Indians were here?
i think about 50000 fifty thousand Indians lived in California fifteen thousand years ago...
How many years did the river Nile exist?
Well It has existed for about 50000 years and i think that the ancient Egyptians made it and lived there
What was one effect of the 6000 50000 BC climate change in northern Africa?
People who lived there moved to the Nile river.
Which method of radiometric dating is used mainly to date the remains of organisms that lived within the 50000 years?
carbon 14 dating
Which method of radiometric dating is used mainly to date the remains of organisms that lived within the last 50000 years?
carbon 14 dating
What was the original name of the British capital and how many people lived there by the year 400?
The original name of the British capital was Londinium. And there were about 50000 people
How could geologists use fossil in rock layer B to date a rock layer in another location?
Geologists can use index fossils from rock layer B to correlate the age of the rocks in another location by matching the presence of these unique fossils. Index fossils are widely distributed and lived for a short period of time, making them useful for dating rock layers. By identifying the same index fossils in both rock layers, geologists can infer that they are of similar age.
What is a No Trade Base?
People who lived in the colonies had to sell and buy materials from their MOTHER COUNTRY ONLY.
What are index fossils useful for?
Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
