Are there any countries with exactly the same number of boys and girls?

Worldwide there are more boys than girls. It is believed that for every 100 girls born, 107 boys are born. Over time, the populations even out a bit due to differing factors, for example war, accidents etc.

Due to populations being measured in millions, the chance of having exactly the same number of each is highly unlikely. Studies over the years have seen some trends in certain parts for the world. Caribbean countries like Barbados, Haiti and Aruba have tended to have more girls than boys. China and India tend to have more boys than girls. Central African countries like Zambia and DPR Congo tend to have a split closer to 50/50.

What is a hurricane?

A hurricane is a large storm characterised by very strong winds. If a tropical cyclone has winds over 74mph(119km/h) and it forms in the Atlantic Ocean, it is known as a hurricane. There are 5 categories of hurricane numbered 1 to 5. The most severe category 5 hurricanes can have winds up to 200mph(320km/h). The hurricane develops around an area of low pressure(the eye) and the winds rotate in an anti clockwise direction around this point. This is what they look like from space.

A hurricane is specific to the area around the USA. A tropical storm formed in the Indian Ocean is called a cyclone, and one formed in the Western Pacific Ocean is called a typhoon.

City to Equator distance calculator from

A basic way to work it out is to take your latitude and to multiply this by 111.111. This will give you the answer in kilometres. To convert to miles, multiply by 0.621.

Please see below video explaining why the distance you are from the Equator affects the weather you experience.

Clouds are formed when the water vapour in air cools down and forms droplets of water or ice. When lots of these droplets come together they form a cloud.

How do people predict the weather?

The science of weather prediction or forecasting is called meteorology. A person who predicts the weather is a meteorologist.


A meteorologist will collect data from a range of sources to show what the current weather conditions are. They then predict what will happen based on what has happened in the past, when the conditions were the same or similar.

Among the type of data collected is air pressure, temperature, wind speed and direction. This data is collected by weather stations which are dotted around the country.

Where can you find quicksand?

You can find quicksand in many different places. Quicksand is sand that has been mixed with so much water it forms a mixture that is in between a liquid and a solid. It does not actually suck you down, it is just so soft that it can’t support your weight, so you sink into it.
