Final answer:
An alpine tundra is characterized by bare rock, stunted trees, and a lack of hardwood trees.
Step-by-step explanation:
An alpine tundra is characterized by bare rock, stunted trees, and a lack of hardwood trees. Due to the extreme climate and high elevation, the growth of large trees is restricted, resulting in stunted trees or no trees at all. Instead, you will find low-growing vegetation like grasses, mosses, and lichens.
