Why do most isotherms tend to run from east to west?
The general trend of isotherms on the maps is east-west direction. The temperature of tropical region is more than polar region, since it is closer to the equator, for doing so the latitude direction will be east-west.

Why do isotherms generally trend east-west quizlet?
Why do isotherms generally trend east-west? The heating of Earth’s surface by solar radiation is a function of latitude and similar latitudes have similar temperatures. There is differential heating of different latitudes with the seasons depending upon the angle at which the Sun is striking them.
Why do isotherms generally run east-west across the US instead of north south?
The land and the water are the same temperature. The tides shift the trend. Both the Southern and Northern Hemisphere follow a true east-west trend. Earth’s tilt causes the isotherms in the Southern Hemisphere to follow a true east-west trend.
Do isotherms run east?
(2) Isotherms generally run from East to West and are parallel to the latitudes.
Do the coldest global temperatures occur over continents or oceans?
Does the coldest temperature generally occur over continent or ocean? (1 pt) (ANSWER): The continent is generally coldest. 35. Explain why there is a large annual range of temperature (January to July) in Siberia.
How is nighttime minimum influenced by clouds?
How is the nighttime minimum influenced by clouds? Clouds absorb outgoing nighttime radiation from the Earth, acting as a blanket and keeping minimum temperatures warmer than they otherwise would be.
What is horizontal distribution of temperature?
Horizontal Distribution of Temperature The distribution of temperature across latitude over the Earth’s surface is known as the horizontal distribution of temperatures. The horizontal distribution of temperature on Earth is shown by Isotherms. Isotherms are the line joining points that have an equal temperature.
Why are isotherms more irregular in the Northern Hemisphere than in the Southern Hemisphere?
Isotherms are more irregular in the Northern Hemisphere than in the Southern Hemisphere because of the marked contrasts in the distribution pattern of land and water in two hemispheres. They bend towards south making the isotherms more irregular.
Why do isotherms run horizontally?
As the air is warmer over the oceans than over landmasses in the northern hemisphere, the isotherms bend towards the north (poles) when they cross the oceans and to the south (equator) over the continents. Over the land, the temperature decreases sharply and the isotherms bend towards the equator in Europe.
Why does the entire pattern of isotherms shift northward from the January map to the July map?
Question: JANUARY Why does the entire pattern of isotherms shift north on the July map from the January map? The oceans heat faster in the Northern Hemisphere Growth of the Antarctic ice sheet in July pushes isotherms north It follows the migration of the vertical rays of the sun from.
What are the factors that affect the temperature distribution?
Factors Controlling Temperature DistributionThe latitude of the Place.The altitude of the Place.Distance From The Sea.The presence of warm and cold ocean Currents.Local Aspects.
Which are the factors that influence the distribution of temperature?
The factors responsible for the uneven horizontal distribution of temperature are:Latitude. In the previous article, we have studied that the angle of incidence of sun’s rays goes on decreasing from the equator towards the poles. Altitude. Land and Sea Contrast. Ocean Currents. Air Masses. Vegetation Cover.
Why are temperature isotherms straighter in the Southern Hemisphere?
As the land surface area is much larger in the Northern Hemisphere compared to that in the Southern Hemisphere, the effects of landmass and ocean currents are more pronounced. Over the land the temperature decreases sharply and the isotherms bend towards south in Europe.

Why are isotherms not straight?
Isotherms are lines of equal temperature. Isobars are lines of equal pressure. As you can see, none of the lines are straight.
