Fossils found in rocks can help scientists correlate and match rocks across different regions because specific types of fossils can provide information about the age of the rocks they are found in. By comparing the types of fossils in different rock layers, geologists can determine the relative ages of those rocks and create a timeline of events in Earth's history. This technique is known as biostratigraphy.

How is a index fossil like a key bed?
An index fossil is a particular fossil used to define and identify a particular time period in the geologic timescale. A key bed is a specific layer of rock or sediment that can be used as a marker for correlating rocks across different locations. Both are useful tools in stratigraphy for dating and correlating rock layers.
Can you show me dinosaur fossils?
No. I can not show you dinosaur fossils. But, if you go to a large natural history museum in a large city, you can see dinosaur fossils. New York City has the Museum of Natural History. Chicago has the Field Museum. Other large cities all over the world have such museums that have dinosaur fossils. It should not be too difficult for you to get to such a major city.
Why proteins and polysaccharides cannot diffuse through the membrance?
They are too large and usually contain hydrophilic regions which prevent movement across the hydrophobic core of the plasma membrane.
What is the two elements named for large regions?
Americium and Europium are the elements named for large regions which include several countries.
Could you throw a rock across a megalopolis?
No, it is physically impossible to throw a rock across a megalopolis due to the vast size of these densely populated regions. Additionally, throwing a rock in a heavily populated area could pose a danger to people and property.
What is the theory that suggested the earth once had a supercontinent?
The theory that suggests the Earth once had a supercontinent is called Pangaea. It proposes that all current continents were once connected as one large landmass before breaking apart and moving to their current positions. The evidence for this theory includes the matching shapes of continents, similar geologic formations across different continents, and the distribution of fossils.

Have found fossils on the top of mountains what do they infer?
Large plate tectonics or the fossils had wings.
What are large nebula called?
Large nebulae are often referred to as "giant molecular clouds" or "super star clusters." These nebulae can span hundreds of light-years across and are regions where stars are born.
What evidence did alfred wegener have for pangea?
Alfred Wegener had several lines of evidence to support his idea of Pangaea, including the fit of the continents, similarities in rock formations and fossils across continents, and the presence of past glacial evidence in regions that are now separated by large distances. Additionally, Wegener noted similarities in climate and geological features that suggested the continents were once connected.

Are fossil fuels fossils?
Yes. They are a large group of fossils which are full of the energy of the dead creatures or plants which formed them.
Matching on different continents are evidence for continental drift?
Yes, matching rock formations and fossils on different continents provide evidence for continental drift. These similarities suggest that the continents were once connected and have since moved apart. This supports the theory of plate tectonics, which explains how the Earth's lithosphere is divided into several large plates that move and interact with each other.
Why proteins and polysaccharides cannot diffuse through the membrance?
They are too large and usually contain hydrophilic regions which prevent movement across the hydrophobic core of the plasma membrane.
What was alfred wegeners evidence for continental drift?
Alfred Wegener's evidence for continental drift included the jigsaw-like fit of continents, similarities in rock formations and fossils across continents, and matching mountain ranges. Additionally, he observed similar ancient climates found on continents that are now separated by oceans.
What place is known for large amounts of fossils and dinosaur footprints in Texas?
Big Bend National Park has many fossils. The fossils are not only of dinosaurs; fossils of Quetzalcoatlus, the largest known flying reptile, come from this area.
What natural regions of California have the most large regions?
Columbia valley
