What is the meaning of weather and climate? Copy the definition for: Weather = the state of the atmosphere around us (changes every day) Climate = the average weather over a period of time (many years)

The 4 main parts of the weather Precipitation (How much it has rained / snowed and how wet it is) Temperature (How hot or cold it is) Visibility (How much we can see Is it foggy / dusty?) Wind (How fast it is and which direction it will travel)

Final Task – Build a sentence Level 3/C The word weather means… The word climate means. Describe what the weather it is like today. Level 4/B The word weather means. The word climate means. The weather today is… (use specific examples like wind, visibility, precipitation) Level 5/A The difference between weather and climate is… The weather today is… (use examples like wind, visibility, precipitation) The weather in the UK is… (use examples like wind, visibility, precipitation) It is important for humans to know the weather because…

The Water Cycle

The Water Cycle in more detail

Places get warm because of the _______. It heats up the ________, which heats the ______. The sun also _______ wind. The warm air ________, so ______ air ________ in to replace it. This cold air is ______. The water from the oceans __________ to become a gas ( _________ __________). As warm air rises it ________ down. The water vapour ____________. That’s why we get ________. When the clouds become too _________, it rains. Sometimes when the weather is very ________ the water droplets may fall as __________, hailstone or sleet. The Water Cycle: Test Rain causes wind rises rising raining sun heating evaporates snow condenses evaporation condensation heavy clear windy water vapour cools cooling.

The units of temperature are degrees Celsius °C or degrees Fahrenheit °F. (Like MPH and KMPH) Temperature is a measure of how warm or cool it is. Temperature Most thermometers are made so liquid (mercury or spirit) in the bulb at the bottom expands as it gets warm and rises up a tube. Temperatures are measured in the shade, so the sun’s rays do not heat up the instrument being used. Temperature is measured using a thermometer. How is temperature measured?

The force exerted on the Earth by the air above. Air pressure is measured using a barometer. It records it in millibars (mB) Air pressure Air pressure changes with height, the higher up we go, the more air pressure.

Wind Direction: A Weather vane records the direction the wind is blowing in. It spins and points towards the direction. A compass direction can be calculated: – North – South – East – West

Wind speed is a measure of how fast the air is moving. It is measured using an anemometer Wind speed Wind is simply moving air. An anemometer has metal cups that rotate in the wind. The stronger the wind, the faster the cups turn.

Rainfall is measured using a rain gauge. Precipitation: Rainfall Rain is a type of precipitation, Snow, sleet, hail, dew and fog are also types of precipitation. Precipitation occurs when water vapour in the air cools and condenses into water droplets. Rainfall is usually measured in millimetres (mm).

Cloud Cover Your eyes are the most useful tools to measure the weather You can look at the sky and see how much is covered in cloud We record this in Oktas 1 Okta is ⅛th A full sky of cloud would be 8 Oktas Your eyes are the most useful tools to measure the weather You can look at the sky and see how much is covered in cloud We record this in Oktas 1 Okta is ⅛th A full sky of cloud would be 8 Oktas

It uses a scale from 0 to 12. The Beaufort scale measures wind intensity using the effects of wind to estimate its speed. Beaufort scale 0 on the scale means there is no wind. How is wind speed estimated without an anemometer? 12 indicates hurricane conditions.
