Question

What prevents trees from growing in the Tundra


Wildfires


Permafrost


Droughts

Answer 1

The primary factor that prevents trees from growing in the tundra is **permafrost**. Permafrost is a layer of permanently frozen ground that restricts root development and access to nutrients and water that trees require to grow. Additionally, the harsh climate, characterized by low temperatures, short growing seasons, and limited precipitation, further limits tree growth in tundra regions. Wildfires and droughts are not significant factors in the tundra compared to the effects of permafrost.
