Zircon (ZrSiO4) forms in magma as it cools into igneous rock. It is also useful for numerical dating.
a. If you walk on a modern New Jersey beach, then you will walk on some zircon sand grains. Yet if you determine the numerical age of the zircons, it does not indicate a modern age (zero years) for the beach. Why?
b. Suggest a rule that geologists should follow when they date rocks based on the radiometric ages of crystals inside the rocks.
Answer:
Zircon is essential element in the formation of igneous ricks.
Explanation:
Zircon crystal commonly grow in rocks and are very small in size. Zircon forms magma ad the lavas as it cools and thus is useful for absolute dating but does not indicate modern age for the beach. Due to the structure of the crystal, as it solidifies in magma. Once make sure that the crystal formed inside the ricks are formed at the same time as the rock itself. As the ricks are formed in different environments just beneath the surface of the earth.Dân cư châu Âu thuộc chủng tộc: *

2/5/g + 3h - 6 when g = 10 and h =6
Answer:
18.04
Explanation:
2/5/g + 3h - 6 when g = 10 and h =6
You can simplify that to 2 ÷ 5 ÷ 10 + 3 × 6
Then you follow PEMDAS
First you do 2 divided by 5 which equals 0.4
So now you have 0.4 ÷ 10 + 3 × 6
Now you divided 0.4 by 10 which is 0.04
0.04 + 3 × 6
According to PEMDAS now you do 3 times 6 which is 18
Finally 0.04 + 18 = 18.04
Imagine that you are standing on a beach but cannot swim. Your friend encourages you to walk into the surf zone created by incoming deep water waves that a wavelength of 30 meters. Would it be safe to walk out to where the waves are breaking?
Answer:
Explanation:
The water depth in the surf zone is between 5 to 10 meters deep and with a wavelength of 30 meters, the speed of the wave is considerably fast such that control for safety may be difficult
Also the speed of the wave is directly related to the depth of the water which means that where the wave described above is fast as well as the rip current, also the water depth is expected to be considerable for a non swimmer
It is best to seek for sign post regarding safe areas and do not go into the water where there are no lifeguards or marked safe zones.
write a note on alternative energy resourse
Answer:
Alternative Energy refers to energy sources other than fossil fuels. This includes all renewable sources and nuclear. Nuclear is not classified as a renewable energy source. A renewable energy source is produced from sources that do not deplete or can be replenished within a human’s lifetime. Nuclear is produced from mined elements like uranium and thorium which cannot be replenished.

Choose the true statement about the nitrogen cycle.
a. Bacteria take nitrogen from the atmosphere and convert it into sugars.
b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
c. Nitrogen makes up about 22% of the atmosphere's composition.
d. Animals release nitrogen through urination and by dying.
The true statement about the nitrogen cycle is that: b. Nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.
Nitrogen is a chemical element with the symbol "N" and it has an atomic number of 7.
Basically, it is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell. Therefore, nitrogen has two (5) valence electrons.
Nitrogen cycle can be defined as a repeating biogeochemical process which typically involves the interconversion or circulation of nitrogen and its compounds by the actions of both living organisms and non-living things in the environment such as nitrogen fixation and decomposition. Thus, it is biogeochemical process that converts nitrogen gas into organic substances and then back to nitrogen in air.
In the real world, it is known that the leaves of plants such as peanuts, soybeans and clover contain nitrogen in a very significant amount.
In conclusion, true statement about the nitrogen cycle is that nitrogen is contained in the leaves of plants such as peanuts, soybeans and clover.

Describe the change in the Moon's phase that takes place over the span of one cycle.
Answer:
Las fases lunares son los cambios en la forma de la parte iluminada de la Luna cuando es vista por un observador en la Tierra. Estos cambios son cíclicos de acuerdo a la posición de la Luna respeto a la Tierra y al Sol. ... A medida que la Luna orbita alrededor de la Tierra, parece que continuamente cambia de forma.
Explanation:
Answer:
A different section of the moon's face is lit up by the sun, causing it to show different phases.
Explanation:
How do the phases of the moon change?The moon's location changes daily as it goes through its 29-day orbit. It is between the Earth and the sun at times and behind us at other times. As a result, the sun illuminates a different area of the moon's face, causing it to show different phases.
What happens to the moon's phases during the period of a month?We don't see the Moon as it moves between the Sun and the Earth because the side reflecting the Sun is facing away from the Earth. It's the new moon.So, while it appears like the Moon is changing shape over the course of a month, this is not the case. The Moon's orbit around Earth causes the phases to change.Moon Phases-Moon phases: New Moon, First Quarter, Full Moon, and Last Quarter
There are also four secondary phases: Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent.

After capital flight
Now, suppose that Mexico experiences a sudden bout of political turmoil, which causes world financial markets to become uneasy. Because people now view Mexico as unstable, they decide to pull some of their assets out of Mexico and put them into more stable economies. This unexpected shock to the demand for assets in Mexico is known as capital flight.
Shift the NCO curve to illustrate the effect of capital flight. Then, on the graph representing the market for loanable funds, shift the demand curve, the supply curve, or both to reflect the change caused by the shift in NCO.
Note: You will not be graded on your final placement of the curves on the graph, but you will need to shift them correctly in order to answer the questions that follow.
Determine the equilibrium interest rate after capital flight occurs, and enter it into the second row of the table. Then determine the level of NCO that occurs along the new NCO curve at the new equilibrium interest rate.
Finally, show the effect of the change in NCO on the market for foreign exchange by shifting either the supply curve, the demand curve, or both.

What is supply and demand?Supply in economics exists described as the total amount of a provided product or service a supplier offers to consumers at a provided period and a conveyed price level. It exists usually specified by market movement.
Demand exists in the quantity of a good that consumers stand willing and able to purchase at different prices during a provided period. The connection between price and quantity demand exists also named the demand curve.
supply and demand exist as an economic model of price decisions in a market. It postulates that holding all else equivalent, in a competitive market, the unit price for a certain good, or other traded item such as labor or liquid financial assets, will vary until it determines at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. It creates the theoretical foundation of modern economics.
