What is the key feature of weather maps that shows areas of equal air pressure and temperature?

• Curved lines

• Wavy lines

• Straight lines

• Dotted lines

Answer explanation

Isobars are curved lines on weather maps that connect areas of equal air pressure. They help visualize high and low pressure systems.

Which layer of the atmosphere has the highest altitude?

• Troposphere

• Stratosphere

• Thermosphere

• Mesosphere

Answer explanation

The thermosphere is the layer of the atmosphere with the highest altitude. It extends from about 80 kilometers above the Earth's surface to the edge of space.

What is the main purpose of weather maps?

• To display weather observations

• To indicate air mass boundaries

• To predict weather

• To show air measurements

Answer explanation
