Isotherms connect points of equal temperature on a weather map. The lines of isotherms naturally run parallel to each other. Their spacing indicates temperature variance.

How many swamps are in America?
By "in America", that would mean Canada, United States, and South America. If you mean only in the US, there are vast areas of swamps in the south-eastern States. But as well, wetlands exist in many States across the US. They would be too numerous to count.
How many people in the US use solar energy?
60 percent Generally, people in the states that get most sunshine (Southwest, Great Plains, California) use the most solar energy resources.
When incident angle is equal to critical angle then angle of refraction will be what?
When the angle of incidence equals the critical angle, there is no refraction wave as we usually understand it. The result is a surface wave. Let us suppose we are asking about light incident on a flat interface between to mediums which are transparent (nonabsorbing). The formula for the angle of refraction says the angle of refraction approaches 90 degrees, so the direction the wave would be traveling would be parallel to the interface. The same formulas in electromagnetic theory will also predict that the energy transmitted across the surface decreases to zero as the angle of incidence increases towards the critical angle. That is the equivalent to the more common statement that there is total internal refection. Advanced mathematical treatments of this topic show that the electromagnetic field does exist on the transmission side of the interface and that energy is flowing parallel to the interface in that region. That is the surface wave. The energy in the surface wave decays exponentially with distance from the interface into the transmission region.
In the 1950s the US spent a large amount of money building the Interstate system of highways This system links major cities across the country what was a desirable cons?
If my memory is still good ten that happened at a time when unemployment was high and money was hard to come by. If the current US government can afford to keep the Interstate Highway system in good repair then it will last a long time
How are we able to see things around us?
Visible light from the Sun is refracted as it enters our eyes as parallel light rays. The light rays are converged to a point on our retina by the lens in our eyes. The inverted image produced is then sent chemically to the brain via the optic nerve where it is interpreted by our brains as a virtual image (the image that we see)

Did the US attack the troops in Korea across the 38th parallel?
30,000
What is the most Northerner state in the US?
Alaska is the northernmost US state.In the 48 lower (contiguous) states, the northernmost is Minnesota, which extends slightly across the 49th parallel at the Lake of the Woods.
What state is the most northern in the US?
Alaska is the northernmost US state.In the 48 lower (contiguous) states, the northernmost is Minnesota, which extends slightly across the 49th parallel at the Lake of the Woods.
What types of crops are raised in the US?
It depends on what region of the US, but generally speaking across multiple regions:corn (maize)wheatoatsother grainsnumerous types of vegetablescottontobaccoOther crops like:peachesorangesapplescherriesstawberries
Which parallel separates western Canada from the western US?
The 49th Parallel
Which is a quadlirateral that has one pair of parallel and a pair that's not parallel?
A trapezium (US: trapezoid).
Is the The Panama Canal is the only way to travel from one side of the country to the other.?
You can drive across the US, you can take a bus across the US, you can fly across the US, you can take the train across the US.
Where was korea divided after world war 2?
After the defeat of Japan in 1945, the 38th parallel was chosen to divide the Korean peninsula into two US and Soviet occupied zones. The line dividing North and South Korea is still often referred to as the 38th parallel, but the border is no longer parallel to the equator and rather runs diagonally across the peninsula.
What quadrilateral has opposite sides that are not parallel?
A trapezium (US) has no sides parallel, while a trapezoid has one set of unequal parallel sides.
Is Appalachian a mountain parallel to the east coast or the west coast of US?
Since parts of the east and west coasts of the US are roughly parallel, something parallel to one of them would be parallel to the other. The Appalachians are closer to the east coast than the west.
What directions do weather patterns generally move across the US?
Weather patterns in the contiguous 48 states almost invariably move west to east overall.
