Diffrences between tundra type climate and polar climate

Distinction from Tundra Climate

For example, tundra climates usually have a month in which the average temperature rises beyond the freezing point, while this does not occur in polar climates. The hotter month allows the ice in tundra climates to melt, which enable plants and animals to survive.

Endogenic process

Explanation:

The endogenic process is usually defined as those processes that are originated from the interior of the earth and takes place at greater depth, which eventually gives rise to the formation of the various types of landforms. These take place in an extensively large area, especially along the marginal areas of the continents, mostly due to the continuous plate motion, thereby creating various types of geological settings in different areas. Some of the examples of the endogenic process are folds, faults, earthquakes, volcanoes, and many more.  

Thus, the endogenic processes are responsible for the formation of continental landforms.
