1- Brachiopods are marine animals with large shells. They live in Coral Reef, in the Ocean.
This is a picture of a brachiopod.2- Fossils are great assets in history. With a fossil we can carbon date and find out the age of a bone.
We can also use fossils to learn what type of animal or plant lived in a given area. For example, in the Grand Canyon it would not be uncommon to find a fossil of a cactus in the future. This would tell future generations that the Grand Canyon is dry and hot.
Apart from telling you about the climate fossils can also tell you about what types of animals lived in a given area. If you find the fossil of a fish on a sand bed, you can infer that perhaps at one time that area may have been covered by water.
3- Uniformitarianism assumes that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe.

The above link is a discussion taking place at the Grand Canyon regarding this very topic
4-
Sedimentary rocks are the only type of rock that can contain fossils, the remains or imprints of dead organisms. In nature, dead organisms are usually quickly removed by scavengers, bacteria, rotting and erosion.

The above video shows and discusses fossils and sedimentary ROCKS. You only need to watch the first 2 minutes the rest is pretty advance, but entertaining if you would like to view it. (You don't have to write this statement here if you are writing it to study)
5- According to fossils that we have found do you know how old the Earth is?
4.5 Billion years. Yes that is older than I your science teacher.
6- Uplifting is nothing more than land being raised to a higher level.

7- Erosion is moving sediments from one area to another

This video illustrates Weathering, Erosion and Deposition in only 60 seconds (VERY EASY TO Understand)
In seeing the video above it's easy to understand why running water, the Colorado River, is the main method of Erosion in the Grand Canyon.
8- The Principle of Superposition states that Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top. In other words,
oldest on the bottom and newest on top. 9- Remember the following careers:
Geologists study Rocks
Archaelogists study fossils
Botanists, study plants
10- As seen in the video above weathering is nothing more than the breaking down of rock. DO NOT confuse it with the WEATHER. It doesn't have to do with weather. A rock can break in good or bad weather.
A great example of weathering ICE WEDGING.. because it breaks down rock, not because it happens in cold weather, remember weathering can happen in ANY TYPE of weather.An avalanche is caused only by gravity, nothing else. Look at the this video of an avalanche in New Zealand. The snow accumulates until gravity eventually just pulls is down the side of a mountain.

11- What is Mechanical Weathering, breaking down rock through a physical process, but Chemical Weathering is breaking is down in a chemical reaction.
Physical weathering would be the lab where be made sand from shaking the stones. Chemical weathering is the lab where we applied the acid to the rocks and it fizzed
We will review this information in class as well and have a the Science Feud Face off for points on Wednesday, be prepared to earn points...
