why do two dimensional maps of earth have distortions

Because the only way to properly represent places on a sphere is on another sphere. a flat map cannot properly depict the distances between more than three different places. Imagine three points on the surface of a ball, all out of 'sight' of each other because of the curvature of the ball. If you draw a straight ling between each of them you would get a 'triangle' whose lines curve around the surface of the ball.

If you measure those lines and plot them on a map, you could transfer each of them exactly - but, if there was a fourth point involved you would not be able to accurately represent the distances between each point and the other three. Earth is three dimentional, but maps are two dimentional~ apex
LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE).

We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina.

We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you. Donвt worry! The lesson plans, articles, and textbooks you use and love arenвt going away.

They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know itвs important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, weвre directing our resources into our newest efforts, so we wonвt be adding to the archive or updating its contents.

This means that as the North Carolina Standard Course of Study changes in the future, we wonвt be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.
