The strand of DNA that is being continually created is known as the leading strand.
The strand that is being created in sections/loops is known as the lagging strand.
The reason that these two strands are created differently is because the two strands of DNA run in different directions (they are anti-parallel). This means that because new nucleotides can only be added in a 5'-3' direction, the two strands cannot be created in the same method.

5'-3' : One strand
Leading strands are one of the two newly synthesized DNA strands during DNA replication. They are synthesized in a continuous manner in the 5' to 3' direction, following the replication fork. The leading strand is synthesized in the same direction as the replication fork is moving, allowing for continuous synthesis.

5'-3' : One strand
A lagging strand is one of two strands of DNA found at the replication fork, or junction, in the double helix; the other strand is called the leading strand. A lagging strand requires a slight delay before undergoing replication, and it must undergo replication discontinuously in small fragments.
The DNA replication fork is where the replication origin forms the Y shape. The replication fork moves down the DNA strand to the strand's end, resulting in every replication fork having a twin.
