This technique allows the user to create a protective wall out of earth. One method of doing this is for the user to convert chakra in their body into an earthen material that they spit from their mouth; the more skilled the user, the greater the volume of earth that can be created. The earth quickly piles up into a defensive wall, blocking incoming attacks. Although the muddy material is solid on its own, it is further fortified with a coat of chakra, making it more resistant to fire and water than it would otherwise be.
A second method of performing this technique is to instead manipulate pre-existing earth directly: by placing their hands on the ground, users can raise the ground as a barrier in front of them. Walls erected in this way are typically featureless, but users can alter the appearance if they choose; Kakashi Hatake adorns his with bulldog sculptures. Users are not limited to strictly defensive uses for this technique, as they can create walls behind targets to prevent them from escaping or even to entirely surround and encase said targets. The anime shows users creating these walls from afar.
In Kakashi Retsuden, the Earth-Style Wall is one of several techniques that Kakashi specifically improves his ability with after the Fourth Shinobi World War, to make up for the loss of his Sharingan. His improved Earth-Style Wall is large enough to surround a small village, strong enough to withstand a barrage of cannons, and Kakashi can convert sections of the wall to quartz to negate earth's natural weakness to lightning. Kakashi is able to keep the wall up for over a day, but it tires him out.
