Please help me. I will make it worth your while by giving brainliest answer and 50 points. no BS You will be writing a 5-7 parag
Natali5045456 [20]

Answer:

Explanation: Dear Sirs:

    I am writing today to urge you as strongly as possible to stop your deforestation program in the rain forest there in South America. Although for you the objective is financial gain, for the rest of us it is the destruction of land, habitats, people and eventually, the Earth.

   Deforestation is a process where large areas of forests are cut down to be used for farming, grazing land for cattle, and housing. This is especially true inn the South American rain forest where you are working. These are not necessarily bad things, but the effects of deforestation are devastating. Deforestation is achieved by cutting or burning of trees from a widespread area. Why does this matter?

    When deforestation occurs in an area, animals and plants are forced to move from their natural habitat. For many of these species they are unable to survive in new forced into areas. When the trees are cut down, the stumps are then burned to release nutrients into the soil to enrich it for farming. This is called, "slash and burn." However because of the heavy rains,and no tree roots to hold the soil, the nutrients are washed away and soon the farmers must move to a new area, and start the process all over.

      Further, deforestation can cause climate change. Obviously without the trees available to capture the Greenhouse gases, like carbon dioxide, stopping the gases from accumulating in the atmosphere and warming our planet. Climate change is a real issue that must be addressed if our planet is to survive.

       With all of these problems, what are the benefits? Who wins? Who loses? The benefits are to your company who now have a large tract of freshly cleared land that can be used for farming, cattle grazing, logging or housing. As always the almighty dollar comes to the forefront. The losers are the plants, animals and indigenous people who live in that area. Forced to relocate, many of all the groups will not survive. With the increased use of deforestation, the benefits are far outweighed by the cost- our planet Earth.

        What are the alternatives to land desertification?  There are better and more innovative ways to grow food and clear land, one of which is sustainable land management. It is a process to prevent, minimize, or reverse land degradation. There are organizations worldwide that will help you to find better solutions than deforestation to reduce carbon pollution, to safeguard arable land, repair degradable land and to manage water supplies more effectively.

          In closing, I strongly urge you to reconsider what you are doing in an area that can ill afford any more destruction. Why does it matter? Perhaps it doesn't to us in 2020, but to our children's children it will matter greatly if climate change destroys the Earth.

Analysis of a rock sample that it contains 6.25% of its original uranium-235. How old is the rock? How do you know?
Andrews [41]

Answer:

The age of the rock = 2800.6 million years = 2.8 billion years.

A simple method of analysis similar to Carbon dating is used to obtain the required age of the rock. Radioactive substances decay according to first order reaction kinetics. So, plugging all the required parameters into the general equation for amount of substance left in a first order decay gives us the age of the rock.

Explanation:

Half life of Uranium-235 = 700 million years (from literature)

The decay of radioactive substances follow first order reaction kinetics.

The general equation is given as

A(t) = A₀ e⁻ᵏᵗ

A(t) = Amount of radioactive substance left after a particular time = 6.25%

A₀ = initial amount of radioactive substance = 100%

t = time that has passed since the beginning = age of the rock = ?

k = decay constant

The decay constant is related to the half life (T) through the relation,

k = (In 2)/T

k = (0.693/700) = 0.00099 /million years

A(t) = A₀ e⁻ᵏᵗ

6.25 = 100 e⁻ᵏᵗ

0.0625 = e⁻ᵏᵗ

In e⁻ᵏᵗ = In 0.0625 = -2.7726

-kt = - 2.7726

t = (2.7726/0.00099) = 2800.6 million years

t = 2.8 billion years.

Hope this Helps!!!

Why have we not found examples in the fossil record of every animal that ever lived on earth? select all that apply. select all
Reptile [31]
Many fossils remain buried
Rocks contain the history of life...


Btw the animal ones don't count i think cuz fossils can be anything like teeth, bones or anything not just animals it can be formed by leaves as well so just for extra guidance i believe the ones that state animals are probably not the options to choose due to the fact that fossils are not just living organisms they're anything that has been buried and decomposed over many years and layers of sediments cover it over many years compression may alter the shape of the fossil aswell!

Hope that extra info helps for a bit of guidance!
