Tessera is a unique feature of Venus, and is also known as "complex ridged terrain". These features are found on some of the Venus Plateau Highlands.
Tessera is created is by a shortening of the crust. That is, when the crust is pushed together, the surface folds, buckles, and breaks. This process
may be related to the process of mountain-building on Earth. But,
because Venus does not have continental drift, the process must occur somewhat
differently. Nevertheless, tessera provide evidence that the surface of Venus may be in motion.
