Distinguish between isobar and isotherm.

Isobars and isotherms are both terms used in meteorology and geography to describe different aspects of atmospheric and temperature conditions. Here's how they differ:

Isobar:

Isobars are lines or curves on a weather map that connect points of equal atmospheric pressure.
They are used to represent and visualize variations in air pressure across a geographic area.
Isobars are typically drawn at regular pressure intervals, such as every 4 millibars (mb) or 10 millibars, to show areas of high and low pressure.
Meteorologists use isobars to analyze weather patterns, predict wind direction and speed, and identify the location of high and low-pressure systems. Wind tends to flow perpendicular to isobars, from high-pressure areas to low-pressure areas.
Isotherm:

Isotherms are lines or curves on a weather map that connect points of equal temperature.
They are used to represent and visualize variations in temperature across a geographic area.
Isotherms are typically drawn at regular temperature intervals, such as every 5 degrees Celsius (°C) or 10 degrees Fahrenheit (°F).
Meteorologists use isotherms to analyze temperature patterns, identify temperature gradients, and understand temperature distributions across regions.
Isotherms are especially useful for identifying frontal boundaries, which are transitions between different air masses with contrasting temperatures.
In summary, isobars deal with atmospheric pressure variations, while isotherms deal with temperature variations. Both are essential tools in meteorology for understanding and predicting weather patterns and are often depicted on weather maps to provide valuable information to meteorologists and the public.
