Why do strong storms such as hurricanes usually result in large ocean waves?
A) Hurricanes produce a lot of rain that ends up in oceans
B) A lot of small earthquakes happen during hurricanes
C) Strong winds are produced during hurricanes
D) Hurricanes stir up the ocean floor

Answer:

The sun provides energy for almost everything that happens on Earth. Scientists at the Laboratory for Atmospheric and Space Physics put it clearly: "Solar radiation powers the complex and tightly coupled circulation dynamics, chemistry, and interactions among the atmosphere, oceans, ice, and land that maintain the terrestrial environment as humanity’s habitat." Put another way, just about everything that happens in the atmosphere happens because of solar energy. This can be demonstrated with some specific examples.

Winds

Sunlight hits the Earth most directly at and near the equator. The extra solar energy absorbed there heats up the air, land and water. Heat from the land and water gets sent back up into the air, heating it even more. The hot air rises. Something has to take its place, so cooler air from the north and south rushes in. That creates airflow -- a circuit from the equator up and splitting to the north and south, then cooling and falling back down to the surface and reversing direction to head toward the equator again. Add in effects of the Earth's rotation and you get trade winds -- the constant flow of air across the Earth's surface. Even though the winds are modified by the Earth's rotation, it's important to realize they aren't created by the Earth's rotation. Without solar energy there would be no trade winds or jet streams.

The Ionosphere

Some wavelengths of solar energy are powerful enough to split molecules apart. They do this by giving so much energy to an electron that it shoots right out of the molecule. That's a process called ionization, and the positively charged atoms that are left behind are called ions. In the upper atmosphere, 80 kilometers (50 miles) above the surface, oxygen molecules absorb ultraviolet wavelengths -- solar radiation wavelengths between 120 and 180 nanometers (billionths of a meter). Because sunlight creates ions at that altitude, that layer of the atmosphere is called the ionosphere. Sunlight affects the Earth's atmosphere, but a side-effect is that the atmosphere absorbs this dangerous ultraviolet radiation.

The Ozone Layer

About 25 kilometers (15 miles) above the surface the atmosphere is far denser than in the ionosphere. Here is the highest density of ozone molecules. Regular oxygen molecules are made from two oxygen atoms; ozone is made from three oxygen atoms. The ionosphere absorbs the 120- to 180-nanometer ultraviolet, the ozone beneath absorbs ultraviolet radiation from 180 to 340 nanometers. There's a natural balance because ultraviolet light splits an ozone molecule into a two-atom oxygen molecule and a single oxygen atom; but when a single atom crashes into another oxygen molecule, ultraviolet light helps them join together to make a new oxygen molecule. Again, a happy coincidence is that the photochemistry taking place at the ozone layer absorbs much ultraviolet radiation that would otherwise make it to Earth and create a hazard for living organisms.

Water and Weather

Another critical component of the atmosphere is water vapor. Water vapor carries heat more easily than gases, so the circulation of water vapor is of critical importance for weather. It's also of critical importance for life on Earth, as water from the oceans is heated by sunlight to rise into the atmosphere where winds blow it over the land. When the water cools, it returns to the surface as rain. The movement of storm fronts is largely the result of collisions between air masses with different water content. Every gust of wind, every storm you have ever seen, every tornado and hurricane was therefore driven by solar energy.

Answer:

1/8

Explanation:

Use logic,

every one hour, half of a radioactive remains

for the first hour, half remains

for the second hour, half of half remains or quarter remains

for the third hour, 1/2 of 1/2 of 1/2 or 1/8 remains

or use this equation

[tex]n = r ({ \frac{1}{2} })^{ \frac{f}{t} } [/tex]

where

n = amount after f time

r = amount of the original isotope

f = time

t = half-life

Answer:True

Explanation:

Most of the transition metals—those metals in the center d-block of the periodic table—are polyvalent. Since they can form cations with different charges, those charges must be specified when naming the ions and when naming compounds containing those ions.

Answer:

D. the amount of oxygen collected over a period of 12 hours

Explanation:

Photosynthesis is a metabolic reaction performed by the cells of plant. In this reaction, light is used as an energy source to combine carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen gas (O2) as products. In every chemical reaction including photosynthesis, an increase in concentration of reactants will increase the rate of the reaction, which is evident in the amount of products formed.

According to this question where a student is performing an investigation to determine the relationship between a higher than normal concentration of carbon dioxide gas and the rate of photosynthesis. After increasing the concentration of carbon dioxide in water, the student illuminated the plant with a light and collected the bubbles of oxygen gas that were given off from the cut end of the submerged plant.

Based on the above explanation, the best indicator of the rate of photosynthesis in this investigation will be THE AMOUNT OF OXYGEN COLLECTED OVER A PERIOD OF 12 HOURS.

Answer:

This is a mole of   Ca₅ (PO₄)₃OH

  In this compound we have:

  5 moles of Ca

  3 mole of P

   13 mole of O

   1 mole of H

The two, eight, and eighteen electrons can be filled in the first, second, and third energy levels respectively.

The electrons revolve in different orbits are known as energy levels or stationary states. These energy levels are numbered as n = 1, 2, 3…… These values are also known as the principal quantum numbers.

The first energy level is also known as 'K' shell or level. The second energy level is called 'L' shell, the third energy level is 'M' shell, and so on.

The electrons present in the K shell contain the least energy whereas the levels contain more energy that is far from the nucleus.

The first energy level (n = 1) can have maximum two electrons in it. The second energy level ( n= 2) can have maximum eight electrons and the third energy level can fill maximum eighteen electrons in it.

Answer:

64.642

Explanation:

To find the miles per hour of each trip, you would divide the miles by the amount of time, in hours, driven. So that leaves you with the first trip being 65 miles per hour on average, and the second trip being about 64.285.

Then, to find the average for both stops, or the entire trip, you would add those two numbers together (65 and 64.285), divide by two (because that's the total number of numbers in the series), and you'd get 64.64!

Finding the Average:

To find the average of a series of numbers, simply add them all together and then divide by the amount of numbers there are.

The downward movement of water through pore spaces and other spaces in soil due to gravity is called infiltration.

Infiltration is greatly due to the force of gravity forcing water through pore spaces downward.

Answer:

2.No. because in an open system, gas will blow up & so, if it's measured, it won't have the equal amount of the reactant. But, if you arrange this reaction in a closed system, then it will be the same.
