<h2>What are fossils?</h2>

Fossils are the remains or impression of plants or animal embedded in rock. They are the remains of dead animals and plants that once lived on this earth in the remote past. Fossils are formed when dead organisms are not completely decomposed.

<h3>2. Fossil record</h3>

The fossil records are referred to as the totality of fossils. It helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. Fossil records can be used to show that organisms changed to meet new conditions

<h3>3. The grand staircase</h3>

The Grand Staircase is referred to as a sequence of sedimentary rock layers that stretch south for 100 miles from Bryce Canyon National Park through Zion National Park and into the Grand Canyon.

The different environmental conditions the Grand Staircase exposed to over this +1 Billion year is heat

4. Based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.

Las Vegas, Nevada is in a desert. How does its rapid population growth affect the
Scrat [10]

Answer:

Many areas of the United States experience explosive population growth. <u>The more people that reside someplace, the more demand there is for water there.</u> Often these urban-growth <u>expansions are unplanned and place extraordinary stress on the water supply system, mainly on the groundwater.</u> <u>The stress often depletes groundwater supply, thereby causing wells to dry up.</u> Then water must be brought from somewhere else to support the local population.

Such situations have occurred all over the United States. For example, increased population growth in the southwestern United States has significantly lowered the water table 50 to 200 feet (depending on the area) since the 1940s. Managing urban growth, efforts to reduce water demand, conservation of the resource, and attempts to increase the water supply all address the problem of exceeding water resource limits.

<u>Human activities affect groundwater quality.</u>

<u>Here are some sources </u>and possible solutions to groundwater pollution:

<u>Agriculture</u>—Reduce usage of pesticides and fertilizers.

<u>Landfills</u>—Monitor for leakage and repair linings.

<u>Underground storage tanks</u>—Remove damaged and unused tanks.

<u>Household wastes</u>—Properly dispose of household hazardous waste.

<u>Septic tank leaks</u>—Properly maintain and repair tanks.

This came from the K12 learning course read this and the answer will be there. I underlined the important parts for the answer.

A 25.0-mL sample of 0.150 M butanoic acid is titrated with a 0.150 M NaOH solution. What is the pH before any base is added? The
hoa [83]
HA ⇄ H⁺ + A⁻ 
so:
\frac{[H^+][A^-]}{[HA]} = 1.5 x 10^{-5}
and now:
\frac{(x)(x)}{(0.150-x)} = 1.5 x 10⁻⁵
x is considered very small compared to 0.15
x² = 2.25 x 10⁻⁶
x = 1.5 x 10⁻³
So [H⁺] = 1.5 x 10⁻³
pH = - log [H⁺] = - log (1.5 x 10⁻³) = 2.83
