Question

The Savanna type of climate is characterised by __________.
(A) Humid summers and humid winters
(B) Humid summers and dry winters
(C) Humid winters and dry summers
(D) Humid throughout the year

Answer 1

Hint:A savanna or savannah is a blended woodland-grassland ecosystem characterised by way of the bushes being sufficiently extensively spaced so that the cover does now not close. The open cover permits enough mild to attain the floor to aid an unbroken herbaceous layer consisting particularly of grasses.

Complete answer:
Savannas keep an open cover notwithstanding an excessive tree density. It is frequently believed that savannas characteristic broadly spaced, scattered trees. However, in many savannas, tree densities are greater and timber are greater often spaced than in forests. The South American savanna sorts cerrado sensu stricto and cerrado dense generally have densities of timber comparable to or greater than that determined in South American tropical forests, with savanna ranging from 800–3300 timber per hectare timber and adjoining forests with 800–2000 trees.
Similarly Guinean savanna has 129 trees, in contrast to 103 for riparian forest, whilst Eastern Australian sclerophyll forests have common tree densities of about a hundred per hectare, similar to savannas in the equal region.
Savannas are additionally characterised by means of seasonal water availability, with the majority of rainfall limited to one season; they are related with numerous kinds of biomes, and are regularly in a transitional region between wooded area and wilderness or grassland. Savanna covers about 20% of the Earth's land area.
Many grassy landscapes and combined communities of trees, shrubs, and grasses had been described as savanna earlier than the center of the nineteenth century, when the thought of a tropical savanna local weather grew to be established. The Köppen local weather classification machine used to be strongly influenced by way of outcomes of temperature and precipitation upon tree growth, and his oversimplified assumptions resulted in a tropical savanna classification thinking which resulted in it being viewed as a "climatic climax" formation.

Hence the correct answer is option (B).

Note:The Savanna local weather is characterised via awesome moist and dry seasons, suggesting excessive temperature during the 12 months (ranging between 240Cand 270C), and ample insolation.
