Understanding Isolines

What is the primary function of an isoline?

• To indicate the direction of wind

• To separate different regions

• To connect points of equal value

• To connect points of different values

Which type of isoline connects points of equal air pressure?

• Isotachs

• Isotherms

• Contour lines

• Isobars

When drawing a 250-meter isoline, what should you ensure?

• It crosses other isolines

• It forms a closed loop or runs off the map

• It joins with a 300-meter isoline

• It represents different values

What is a common mistake to avoid when drawing isolines?

• Drawing them as straight lines

• Crossing them over each other

• Using different colors

• Starting from the center of the map

What is the final step in completing an isoline map?

• Erasing all previous lines

• Drawing the 350-meter isoline

• Ensuring all isolines are parallel

• Drawing the 250-meter isoline
