What is the different in 4 layers of the earth?
The earths 4 layers are: Find Out Yourself Lazy
How can fossils help geologists match rock layers?
If the fossils that the scientists find are very evolutionarily similar, for example, if they are the same species or genus, then that means that the sedimentary rock layers have some correlation to each other since the two extinct animals that turned into the fossils most likely lived during the same time period. This hints that the two rock layers were both exposed to the atmosphere during the same time period.
How geologists tell time?
RocksRocks have many mysteries to them. Many geologists study the rocks to find out the history of earth. What happened in the past? How was it back then? Have you ever wanted to know what the history of your ancestors? Well the same for geologists, they study it to see what was the weather conditions in the past, how old was the rock, was it eroded, and many other things. To determine that, geologists use their tools to find out all these things. One main tool they use is relative dating, or the sequence in which an event took place. For example, if a geologist fined a rock that was cracked almost half way, he/she will predict that an earthquake took place then wind came and eroded it. Basically, relative dating is saying first, second, third etc.However, when geologists bring the exact time something happens it is called absolute dating. Another thing about rocks is, most of the rocks are layered. The bottom layer of the rock is the oldest and the top is the youngest. When a piece of the rock is missing it is called unconformity. Some of the layers in the rock is larger or smaller than the other layer. This is due to compression for sun light or heat. Some layers may be exposed to the sun and some not. Another tool that is used is relative age. Relative age is when geologists bring two rocks from different places but they are the same age. They examine it to see the differences in these two rocks to see the effects on each environment.This is a figure of layers of a rock. This layer is made of many different types of rocks. As shown in the picture some of the layers are large and some are small. Some are dark and some are light. The top is the youngest and the bottom is the oldest. The layers show you the ages of the rocks.Erosion is when weather conditions happen and it moves materials from one place to another using snow, hail, rain, waves, wind etc. Geologists try to discover what happened in the past that made the rocks go from one place to another. Did an earthquake occur? A volcano eruption? A storm? This is one way how rocks travel around the world. This is how sometimes unconformity happens.
How do geologists use fossils to determine rocks age what are this fossils called?
they find the hard part of the fossil
Where do you find coarse grained rock?
true mf
Technology used to find out the different layers of the earth?
The technology used to find out the different layers of the earth is referred to as sonar technology. This is the method that geologists use to find details about the layers of the earth.

Where can I find Which layer of the earths atmosphere has most of earths weather?
Outside your window, and with an Internet search for "atmospheric layers". The answer is the "troposphere". That's the lowest layer where most of the air is.
What other type of scientists besides geologists would find the theory of plates tectonics useful in their work?
capriologists they study the whole world space, the layers everything so they would find theory of plate tectonics useful
The study of earth layers and the artifacts found in them is called?
The study of earths layer and the artifacts found in them is called archeology. Archeology is used to find out about past organisms.
Why does the principle of original horizontality cause problems for geologists?
the Law of Original Horizontality states that sedimentary layers and lava flows were originally deposited as horizontal sheets. However, they may not be horizontal or flat because they have since been displaced by various movements of the Earth's crusts, and geologists must find out what happened to cause these movements.
What would i find on a contor map?
different heights and depths
Where do you find young seafloor?
in the depths of the oceanic crust floor.
Where would you be most likely to find granite in earths mantle or earths continents?
you will find it in earths mantle because it is a kind of an igneous rock
How many elements make up earths crust?
How many elements make up the earths crust? The earths crust is made of many layers..You can find clay and very good soil. But that is if you dig a little way down. the earth has a center which is called the core of the earth. Inside this core is lava and is incredibly hot. Like the sun but not as hot..
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.
Where could one find information about the Blackrock Depths?
You can find information about Blackrock Depths on the website Wow Wiki. This website contain a lots of information about legends, role playing games and video games.
