What are the classifications of seasonal climate?
The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are
A (tropical), B (dry), C (temperate), D (continental), and E (polar)
. Each group and subgroup is represented by a letter.
What is called permafrost?
The Short Answer: Permafrost is
any ground that remains completely frozen
—32°F (0°C) or colder—for at least two years straight. These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.

.
How does topography affect climate?
The topography of an area
can influence the weather and climate
. Topography is the relief of an area. If an area is close to a body of water it tends to make milder climates. Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture.
What causes the freezing temperatures of the high latitude subarctic climate?
What causes the freezing temperatures of the high-latitude, subarctic climate?
The lack of direct sunlight
causes freezing temperatures in high-latitude climates.
What zones go with that ecosystem?

What is the difference between an ecosystem Region province and a biome?
According to National Geographic, the biome definition is an area on the planet that is classified by the animals and plants in that area. An ecosystem, on the other hand, is defined as
a biological community of interactions between all living (biotic) and nonliving (abiotic) things in a particular area

physical climatology, dynamic climatology, tornado climatology, regional climatology, bioclimatology, and synoptic climatology
.
Which are the major climate zones classified by trewartha?

Which countries have permafrost?
Permafrost is widespread in the northern part of the Northern Hemisphere, where it occurs in 85 percent of Alaska, 55 percent of
Russia and Canada
, and probably all of Antarctica. Permafrost is more widespread and extends to greater depths in the north than in the south.
What is permafrost in geography Upsc?
Permafrost is
a permanently frozen layer below Earth’s surface

Where is sub tropical?
The subtropics are geographic and climate zones located
roughly between the Tropic of Cancer and Tropic of Capricorn and the 40th parallel in both hemispheres
. Subtropical climate regions can exist at high elevations within the tropics, such as across the Mexican Plateau and in Vietnam and southern Taiwan.
What is tropical and sub tropical climate?
Tropical systems are
warm-core weather systems that only form over water
. They have no fronts associated with them but typically generate more rain than extratropical systems. … Subtropical systems are a cross between an extratropical and a tropical system, having characteristics of both. They can be warm- or cold- core.
What is tropical and sub tropical area?
Tropics and Subtropics
The portion of the world found between the Tropics of Cancer and Capricorn is known as the Tropics. The subtropics are
the geographical and climatical zone of the Earth immediately north and south of the Tropics
. … Hurricanes are tropical disturbances with sustained winds exceeding 74 mph.
What is the desert region?
Deserts
cover more than one-fifth of the Earth’s land area
, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. Deserts are part of a wider class of regions called drylands.

Which of the following describes a desert?
A desert is
a region of land that is very dry
because it receives low amounts of precipitation (usually in the form of rain, but it may be snow, mist or fog), often has little coverage by plants, and in which streams dry up unless they are supplied by water from outside the area.

What is sub polar region?
The subarctic climate (also called subpolar climate, or boreal climate) is a
climate characterised by long, usually very cold winters, and short, cool summers
. … Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter.
How does latitude affect climate?
Latitude or distance from the equator –
Temperatures drop the further an area is from the equator due to the curvature of the earth
. … As a result, more energy is lost and temperatures are cooler.
What factors affect the temperature and precipitation of regions?
The temperature characteristics of a region are influenced by natural factors such as latitude, elevation and the presence of ocean currents. The precipitation characteristics of a region are influenced by factors such as
proximity to mountain ranges and prevailing winds
.
What is continental climate zone?

summers are hot to very hot and there’s hardly any rain that falls at all
. Winter days can be cool or warm, and winter nights can be very cold. The air is dry, there are hardly any clouds; the sun is very powerful and you’ll certainly get a massive glare in your eyes.
How does topography affect wind?
The direction and speed of the wind can be greatly affected by topography. Ridges and mountains are barriers to the horizontal movement of air.
The wind is deflected over them adding to the local up-slope convective winds from the surface heating
by the sun. … Winds will also be gusty and spotting is more likely.
How does topography influences regional and local patterns of precipitation?
Topography Affects Rain and Snowfall
Mountains
play an important role in precipitation patterns. Topographic barriers such as mountains and hills force prevailing winds up and over their slopes. … As air cools, this water vapor is forced to condense, depositing rain or snow on windward slopes.
What is orographic type of rainfall?
orographic precipitation, rain, snow, or other
precipitation produced when moist air is lifted as it moves over a mountain range
. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.
What is regional ecology?
An ecoregion (ecological region) or ecozone (ecological zone) is
an ecologically and geographically defined area that is smaller than a bioregion
, which in turn is smaller than a biogeographic realm.
What are the three ecological zones?
- 1 Tropical domain. Mean temperature of all months over 18
o
C. … - 2 Subtropical domain. At least 8 months above 10
o
C. … - 3 Temperate domain. …
- 4 Boreal domain.
What distinguishes one ECO region from another?
Ecoregions are identified by
analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity
(Omernik 1987, 1995). These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology.
