The Grand Canyon began its formation about 5 my ago by the erosive action of the Colorado River. Its sedimentary layer composition reflects its history, keeping fossilized living forms that used to inhabit the area.
--------------------
The Grand Canyon formation began approximately 5 million years ago, thanks to the erosive action of the Colorado River.
The strength of the colorado river caudal, together with deglaciation and humidity factors, began to cause an uncontrollable erosion process in these lands that were previously part of the sea bottom.
Originally many strata and sediments accumulated at the bottom of the ocean. With time these extensive areas were exposed when the Rocoses Mountains got formed by the end of the cretaceous (70 million years ago).
Now, by looking at the composing layers, it is possible to understand its formation.
The Grand Canyon is almost entirely composed of sedimentary rock.
It was formed while sediments of sand and mud got deposited in thick layers at the bottom of the ocean and got compacted through the pass of time until becoming a rock.
Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.
According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
Each layer keeps fossilized organisms that used to inhabit this area in the past.

Pls Hurry!
1. Breakfast Food Company A conducts a research experiment that shows that one of their products, Cereal A, is much healthier than cereals made by other companies. Is this an example confirmation bias? Why or why not?
2. John wants to test sports drinks to find the best one to drink during the soccer season. Every day after practice, John drinks a different sports drink and writes down how good it tastes. At the end of the week, he looks at his data and finds that Sports Drink A is the best. Is this confirmation bias? Why or why not?
Answer:
1. It is confirmation bias because the company conducted a research experiment on their on products. They could have implemented or changed variables that are part of the experiment in order to get the results they would want. It is best to have a third party that don’t work for the company in order to conduct the experiment without biases
2. For this one it could be both yes and no. It could be that John really enjoyed Sports Drink A, so he purposely wrote down the data for the other drink lower. Here he was bias towards what he wants to have a better outcome. Maybe the sport drink A is from a company he likes many of their products. In order to not have confirmation bias, john should get a friend to give him the drinks without the labels, and the drinks should be the same color. That way he only tests the taste and not the way it looks. Both packaging and the color of the drink.

what is known as electronegativity and mention how the electro negativity vary long the periods and down the groups..please i need answers quickly!
Answer:
Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.

Ingrid drew a diagram to compare two ways in which biodiversity can be protected.
Which label belongs in the area marked Y?
has the goal of releasing animals in the wild
is often done in nature preserves
usually protects entire ecosystems
focuses on increasing the population of a single species
Answer:
The answer is often done in nature preserves
Explanation:
The region Y in the diagram represents the action that is is often done in nature preserves. Hence, option b is correct.
What are the ways of biodiversity protection?Captive breeding and habitat preservation are two important ways to protect biodiversity. Captive breeding involves the capture and breeding of endangered species in a controlled environment to increase their population size.
This method is used for species that are in danger of extinction in the wild due to factors such as habitat destruction, poaching, and disease. By breeding the species in captivity, the population can be increased and eventually released back into the wild to help restore the species' population.
Habitat preservation, on the other hand, involves protecting natural habitats from human activities such as logging, mining, and urban development.
By preserving habitats, the native species that rely on these habitats can continue to live and thrive, maintaining a healthy ecosystem. This is crucial for the conservation of biodiversity, as many species are dependent on specific habitats for their survival.
Hence, option b is correct.

Answer:
A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.
B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.
C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.
