Fill in the Blanks

What is the percentage of nitrogen in Earth's atmosphere today?

Fill in the Blanks

Which gas, frequently examined by meteorologists for its role in the greenhouse effect alongside carbon dioxide, is abundant in the atmosphere and influences weather patterns?

Multiple Choice

Which of the following is NOT a reason why the atmosphere is important?

• It is made of many layers.
• It provides gases living things need.
• It provides warm temperatures.
• It protects us from UV rays and meteors.

Multiple Choice

The _________________ is the process by which gases in the atmosphere absorb and give off heat

• ozone layer
• greenhouse effect
• coriolis effect
• thermosphere

Multiple Choice

Why does the troposphere experience (have) the greatest amount of atmospheric pressure compared to the other atmospheric layers?

• It produces the ozone layer.

• It has the highest temperatures.

• It contains a high concentration of air particles.

• It is the region in which weather occurs.

Multiple Choice

Which of these statements BEST describes (explains) temperature as elevation in the atmosphere increases?

• Temperature remains constant with elevation in the thermosphere.

• Temperature remains constant with elevation in the mesosphere.

• Temperature generally decreases with elevation in the stratosphere.

• Temperature generally decreases with elevation in the troposphere.

Multiple Choice

How is the stratosphere different from the troposphere?

• The clouds in the Stratosphere produce more rain.

• The air in the Stratosphere has a greater density.

• The composition of the Stratosphere lacks ozone.

• The temperature of the Stratosphere warms as altitude increases and in the Troposphere the temperature cools as altitude increases.

WEATHER

Weather

Weather refers to the present state of the atmosphere. It could be sunny or cloudy, windy, or still, wet or dry. A complete description of weather includes the type of clouds, temperature, wind speed and direction, precipitation, humidity, and air pressure.

Meteorology is the study of the entire atmosphere, including the weather.

Weather forecasting is important to predict bad weather. The national weather service issues weather alerts and advisories when it anticipates approaching severe thunderstorms or tropical cyclones. This helps to protect life and property.

Importance of Weather forecasting

These factors are affected by many elements such as the surface of the local area and the distance from big water bodies. They influence each other too.

Meteorologists can make weather forecast through observing different weather components by using weather instruments. They observe and analyse the collected data to prepare the weather forecast.
