what is a tundra?

Question

if tundra is the coldest biome why in pictures it is like a grassland.?

Answer 1

In physical geography, tundra is an area where the tree growth is hindered by low temperatures and short growing seasons. The term "tundra" comes from Kildin Sami tū̄ndra, the genitive of tundar, "treeless plain", or according to some, comes from the Finnish word "tunturia", also meaning "treeless plain".

There are three types of tundra: Arctic tundra, Antarctic tundra, and alpine tundra. In all of these types, the dominant vegetation is grasses, mosses, and lichens.

Trees grow in some of the tundra. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree-line or timberline.

Answer 2

the way they taught me in high school was this.
there are regions that rap around( belts all around the world)..
tundra= extream north and south(just below north pole and south).
little to no plant life grows and what does is short lived because of the outragious cold temperatures amd the lack of year round sunlight. the roots never go very deep because of the frozen ground, which is at least a couple of feet deep.
the nothern coniferiuos forsest= here we're talking about pines and the high altitudes they tend to grow in in their natural state.
in the mid u.s. we;re talking about the mid-latitude decidious forest, to include all the wide leaf trees like the maple and the oak. this is my native envirnment. these tend to grow at lower altitudes than the coniferious plants, though both can live on the same ground, if nurtured by people.
the tropical rain forest=jungle. that's the best way to describe it because that's what most people picture. abundant rain fall, really wide leaves that hide the plant life on the forest floor. great oygen producer.
when you get to the equator, everything's reversed. the same for the top and the bottom.

Answer 3

It looks like a grassland as you say because its flora consists mostly of mosses and lichens but also heaths and sometimes species of terrestrial algae and plants.
