Hey I'm an eighth grader and I'm not to good at science. Can you help me with my homework.?

Question

These are 3 questions i really need help on I just don't understand it.

1. Explain how convection is related to the formation of weather systems.

2. How is the Water cycle related to the weather?

3. What are some of the weather factors that forecaster must collect data on in order to predict weather?

Please help me I don't understand this.

Answer 1

Convection is when hot air rises and cold air falls. It is caused by the sun heating up our Earth. When hot air and cold air get close together (like in Kansas) the cold air rushing down and the hot air rushing up makes thunderstorms and tornados. like when you drain a bath tub and it swirls down the drain. This air movement also is what makes the regular wind.

Water evaporates (like puddles and the ocean). It doesn't just hang in the air, but is collected together in the clouds. when enough water is in the cloud, it is heavy. And so it starts to fall to the ground in the form of rain or snow.

Forcasters collect wind speeds and barometric pressure (helps to tell you when the hot air is going up or cold air is coming down). they know that when a cold front (lots of cold air) is moving close to section of warm air (a warm front) that those two types of air will make some weather. Either just rain, or thunderstorms, or just for a very cold day.

Answer 2

1. cool air delves down, while warmer air rises to the top. The warm air usually cools in the cooler, higher sections of the atmosphere and again begins to return back down. Local breezes, wind and even thunderstorms are a result of convection.

2. The recycling of water between the earth and the atmosphere An ecosystem reuses water through the water cycle. Water enters the atmosphere as vapour from bodies of water and from the soil. Plants lose water through the pores in their leaves. Water vapour in the atmosphere condenses and forms clouds. The water droplets return to the earth as rain, snow, sleet, or hail and are used again by plants and animals and the cycle continues.

Answer 3

You're a pretty smart kid, asking three questions in one.
1. If I remember, convection is how heat moves through the air. Where warm air goes versus where cold air goes cause wind and clouds. Clouds bring about hail, rain, sleet and snow.
3. Barometric pressure is important to determine the likelihood of storms. Temperature and humidity are obviously important. Then there's wind direction and speed. Hmm, that's all I can think of.

Aren't these answers found in your book? I'm not always going to be here, you know.

Answer 4

I don't know 1 or 3, but the 2 is easy. The water cycle includes precipitation, which is rain, snow, hail, etc, so that is why it is related to the weather.

Answer 5

ok for the second one it is related to the weather because as the sun evaporates the water it goes up into the sky then as dust mixes with the water it formes a cloud as the water drops in the cloud geet tooo heavy it rains and that is how it is related
