how dose wind cause surface currents
Answer:
Suface currents are mostly caused by the wind because it creates friction as it moves over the water. This friction then forces the water to move in a spiral pattern, creating gyres. In the northern hemisphere, gyres move clockwise; while in the southern hemisphere, they spin counterclockwise.

Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies.The Earth receives ≈174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.Since, 1PW=1000TW
Thus, 174 PW= 174*1000=174,000 TW.

Write an essay about the dangers of Child Labour. ( 250 - 300 words).
Explanation:
Child labour is the working of children of ages under 18 years old for number of hours that contrast their body growth and affects their health badly. This research is studying the affects of child labour on development of countries and trying to prove that the child labour is cause of delaying of some countries due to its effects on education. To prove that an interviews with labour children’s and their families have been made. More over a lot of statistics have been gathered by me of child labour in several countries from uniceff and international labour organization in addition to world health organization .the results which have been indicated is that most of the child labour found around the world is in the developing countries because children leave schools to work so in the future they become untrained adult can work.
i-Introduction
Child labour is the working of young children under the age of 18 years old for large number of hours and in unsuitable jobs .It was noted that The Child labour it is the work of children in un suitable ages for unsuitable work hours or under unhealthy conditions and under certain circumstances that contrast with their body growth and their education and also their ability for creations (February 2, 1992, The Child Labour Situation) . also it was conducted that child labour is breaking of human rights which obstacle there psychological life and their physical activities (international labour organization ). Further more the child labour is mainly found in the developing countries and in Africa and Asia . some statistics The high percentage of child labor occurs mainly in mali with percentage of 54.5 Burkina Fasowith 51 percent, Niger and Uganda with 45 percent and Kenya with 4L3 percent, the report said.Bangladesh had 30.1 percent, Nigeria 25.8 Haiti 25, Turkey 24, Ivory Coast 20.5, Pakistan 17.7 percent, Brazil 16.1 , India 14.4. China U.6, and Egypt 11.2 percent. (INTERNATIONAL JOURNAL OF HUMANITIES AND PEACE. 1997). After all of that the aim of my study is to show the bad effects of child labour .moreover if the child labour has effects on developing countries in delay in development.
ii-Literature review
a-The meaning of child labour
It was noted that The Child labour is the work of children at unsuitable ages for unsuitable work hours or under unhealthy conditions and under certain circumstances that contrast with their body growth and their education .also their ability for creations (February 2, 1992, The Child Labour Situation) . moreover it was conducted that child labour is the breaking of human rights which obstacle there psychological life and their physical activities (international labour organization ).in addition to that there is a positive meaning of child labour i.e. the children can work with their parents in home ,help in family work or get their pocket money from working in the weekends and in the summer vacations (international labour organization ).
b-Causes of child labour :
there are many causes of child labour the main cause for it is poverty of the families . The international labour organization noted that the poverty of the families is the main cause of child labour because the children have tow work to get money which help in keeping their life and the life of their families . in addition to that the families are not capable to pays funds of the schools . also the children who are living in slums and villages which don’t have any educational facilities so they work .more over the work market are demanding more children to worm because they take low salaries and they are less trouble maker than adults for the employer . furthermore it was noted that The children works due to the poverty of their families so they need income to overcome the challenges of the life as a result they need to send their children to the work to get them money. In the other hand they cant send them to the working fields that give high wages as exportation because of restricting laws so they must send them to works of low wages as agriculture or servings fields. They have to work more hours to increase their income even if some of their brothers or sisters in school their parents get them out and send them to work field( number cruncher Putting children to work,By Stephen Nickell,september 2009 · prospect · 15). In the other hand not all the causes are economic causes some of the are from family where children work with their families in farms , shops and different hand made industries said international labour organization .
Answer: Right now roughly 152 million children are victims of child labour, in over 179 countries across the world. Though many governments have laws in place to protect their youth, much of the world is still suffering from a lack of healthy jurisdiction.
Child labour is defined as work that deprives a person of their childhood. Generally, the legal age at which you are allowed to begin working is 15 - 18. Bolivia has the world's lowest legal minimum age requirement, at just 10 years old. However, the majoroty child labour victims are as young as 5 - 11 years of age.
Child labour has be proven detrimental to the physical health, mental health, and development in youth. Often accompanied with depression, drug dependency, premature aging, malnutrition, etc. We have only just brushed the surface of the true depth and impact this issue has on the individual affected. Time is also a limited resource, and it is estimated $176 billion is lost in potential future wages when children engage in labour instead of completing their education. This goes without mentioning the percentage of deaths among child workers.
Most jobs associated with child labour are extremely harmful. Hazardous conditions occur more frequently, and the risk of being exposed to forced labour, debt bondage, serfdom, and illicit activities such as prostXXXitution, porXXography, or drXXug trafficking greaten significantly. It is estimated that over 1 million children involved in child labour are trafficked globally per year.
Overall, Child labour is a pressing issue affecting hundreds of thousands of lives daily across the world. With the extreme conditions, psychological and physical damage, and other risks associated with child labour, it is hard to deny that it is a violation of human rights.
Luckily there are things you can do to help combat this pressing issue. Organizations like The Bureau of International Labour Affairs (ILAB) and World Vision are working hard and fast to reduce the number of children affected, and to strengthen national policies to protect them. There is still work to do, and it's up to American citizens like us to push for more support by contacting our members of congress and raising our voice on behalf of the millions of children suffering worldwide.

Low frequency waves:
A. have high amplitudes.
B. Have long wavelengths.
C. Travel at high speeds.
D. Have short wavelengths.
Answer:
Its A
Explanation:
Its A =Have high amplitudes
Low-frequency waves have long wavelengths. Therefore, option B is correct.
What are waves?
Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.
Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.
Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

Answer:
Water will flow from microbe to the Jam.
Explanation:
Osmosis is defined as the movement of molecules from higher concentration to lower concentration of the solution across a semi-permeable membrane. In osmosis water moves from low concentration of solute to high concentration of solute.
In the given experiment, cell wall of bacteria acts as a semi-permeable membrane and sugar in jam and cytoplasm in bacteria act as solutes. Sugar in jam is strong solution means has high concentration of solute and cytoplasm in bacteria has low concentration of solute, which drives the movement of water from bacteria to the jam.
Hence, the correct answer is "Water will flow from microbe to the Jam."
