1. A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, wherein the tooth assembly includes an adapter configured for attachment to the base edge of the ground engaging implement and having a forwardly extending adapter nose, the ground engaging tip comprising:
a rear edge; a top outer surface; a bottom outer surface, wherein the top outer surface and the bottom outer surface extend forward from the rear edge of the ground engaging tip and converge at a front edge; oppositely disposed lateral outer surfaces extending upwardly from the bottom outer surface to the top outer surface; and an inner surface extending inwardly into the ground engaging tip from the rear edge of the ground engaging tip and defining a nose cavity within the ground engaging tip having a complementary shape to the adapter nose of the adapter for receiving the adapter nose therein, the inner surface comprising:
a bottom inner surface extending inwardly from the rear edge of the ground engaging tip and oriented approximately perpendicular to the rear edge of the ground engaging tip,a front inner surface,a top inner surface having a first support portion proximate the front inner surface and having a rear edge, a second support portion proximate the rear edge of the ground engaging tip and having a front edge, and an intermediate portion extending from the front edge of the second support portion to the rear edge of the first support portion, wherein a distance between the first support portion and the bottom inner surface is less than a distance between the second support portion and the bottom inner surface, and wherein the second support portion of the top inner surface is approximately parallel to the bottom inner surface, and oppositely disposed side inner surfaces extending upwardly from the bottom inner surface to the top inner surface.
