1) Because the sun heats the earth unevenly that means the air's density is different,the lighter, hotter air rises, and the cool air falls, making a circular current, called a convection current.
2)Wind is caused by the sun's energy, the molecules start moving around, eventually causing a a convection current.
3) When air molecules heat up they start moving around, they move around, and bump into each other.
4) The sun provides energy, that causes wind to blow.
1) Convection currents are produced when less-dense air rises and more-dense air falls.
2) The movement of more-dense air to an area where the air is less-dense causes wind.
3) When the air is heated there are less molecules in the air.
4) The sun is the source of energy that causes wind to blow.

1) Convection currents are produced by hot dense air rising, getting cold, and then falling, and that happens over and over.
2) Less dense air goes upward, and the warm and cold air mix and move, causing wind!
3) When air molecules are heated, they get farther apart.
4) Solar energy makes the air warm and cold, which makes the molecules change, causing wind.

1) Convection currents are produce by hot dense air rising then getting cold and falling then it keeps doing that.
2) Less dense air goes upward and the cold and warm air mix, and move causing wind.
3) When air molecules become warm they spread apart.
4) Solar energy changes the temperature of the air molecules that causes wind to blow.

1.)convection currants are produced by uneven heating.
2.)The movement of denser air to lighter air is wind.
3.)when air is heated air molecules rise up from the land.
4.)The source of energy that causes wind to blow is the sun's energy.
1)the convection currents are produced by the uneven heating of the earth's surface.
2)the density of the air causes wind. the cool & dense air sinks and the warm & not-so-dense air rises causing a circle.
3)when air is heated, air molecules rise.
4)the source of energy that causes the wind to blow is the solar energy that comes from the sun.
1. convection currents are produced in the air when warm air rises and cool air falls.
2. wind is caused by the movement of denser air from the sea to warm land.
3. when air is heated, air molecules spread apart.
4. the source of energy that causes the wind to blow is convection currents.
EXPLAIN HOW CONVECTION CURRENTS ARE PRODUCED IN THE AIR:when cold denser air movies from sea to land 1)
2)dense cold air combines with cold air over land.
3)when air is heated,air molecules fly faster.
4)the source of energy that cause the wind blow is the air currunt with densec hot air
1. The convection currents are produced in cool,dense air falls and less-dense, warm air rises.
2. Wind is air go on cool sea, go on hot land, he go up, now he is cold and go down.
3. The molecule go up when air is heated.
4. The source of energy is cool sea and hot land.
A circular movement of fluid that is the result of uneven heating.
What happens to create wind is warm air cools and rises becoming denser,and denser air from the sea warms up and flows over hot land.
When air molecules are heated they bump into each other.
The source of wind is energy from the sun.
1) cool air denses and the warm air combines.
2) when a mass of air is in motion.
3) The warm sir goes up.
4) wind blows by energy from the sun.
1.Convection currents are cause from uneven heating.
2.Denseity of air cause wind.
3.When air molecules are heated,land is heated and it makes the day hotter.
4.Wind is air in motion.air has mass,so mass causes wind.
1) Convection currents are produced in the air when dense cool air flows from the sea to the air.
2) Wind is caused by the movement of denser air.
3) When air is heated, air molecules bounce int each other.
4) The source of energy that causes the wind to blow is solar energy.
1)Convection currents start by air falling in a circle
2)When dencer air rises wind happens
3)they bumb into each other and mor come out
4)solar energy is enegy made by the sun

1.) The circular current is called a convection.
2.) Molecules create wind.
3.)They bang into each other and more come out.
4.)The convection current creates wind that blows from land to sea
1. The circular current is called a convection current.
*convection current: A circular movement of fluid
(such as air)that is the result of uneven heating of the fluid.
2. Wind is air in motion. Air is matter. Air has mass
and takes up space.
3. When air molecules bang into the hot surface of the land,energy transfers to the air molecules.
Because of this
1. convection currents are made by hot and cold air mixing
2.wind is made by solar uneven heating
3. air molecules flow upwards
4.solar energy causes to blow
1.Convention currents are produced in the air when the hot air rises and the cold air falls.
2.wind is caused by the flowing of dense air.
3.When air molecules are heated,it pushes the molecules farther apart.
4.the energy source that causes wind is a convention current.

1.Convection currents are produced in the air when cool and warm come together 2.Wind is caused by denser cool air.Ahmirah and Devanae

1. Convection currents are produced in the air when warm air cools as it goes upward and starts to fall [it goes in a circular motion.
2. Wind is caused by the falling of dense air molecules.
3. When air is heated,molecules go upwards.

1) when air is heted
