Which is the driest continent on earth?
Antarctica is the driest continent on Earth. It receives very little precipitation annually, and a large part of its surface is covered by ice, making it a polar desert.
Which Japanese city was the site of the world's first nuclear attack?
Hiroshima was the Japanese city that was the site of the world's first nuclear attack on August 6, 1945.
What Percentage of rainforest covers the earth?
Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.
What is One plate sinking under another?
Subduction occurs when one tectonic plate slides beneath another into the Earth's mantle at convergent plate boundaries. This process is commonly associated with the formation of deep oceanic trenches and volcanic arcs, and it is a key mechanism driving plate tectonics and shaping the Earth's surface.
What is the lowest place on Earth's land surface?
The Dead Sea Shore in Israel, Jordan with an elevation of -418m (-1,371ft) below sea level.
The Dead Sea
the dead sea area
The hypothesis that continents have slowly moved to there current locations is?
The hypothesis that continents have slowly moved to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains how the Earth's lithosphere is divided into large plates that move and interact with each other. This movement of continents is driven by processes like seafloor spreading and subduction at plate boundaries.
What is Austria's functional region?
Austria's functional region includes neighboring countries like Germany, Switzerland, Czech Republic, Slovakia, Hungary, Slovenia, and Italy, with which Austria has strong economic, social, and transportation links. This region is characterized by high levels of cross-border trade, tourism, and labor mobility. It forms an important economic and cultural hub in Central Europe.
Pangaea was a supercontinent that formed approximately 300 million years ago. It existed during the Paleozoic and early Mesozoic eras, breaking apart to form the continents we know today after about 100 million years.
Why is it difficult to accurately represent the earth on a map?
because it has to be stretched to fit on the map. example, look at Greenland on a map and on a globe. are they the same size or not? NO. the globe is accurate and the map is wrong because it had to be stretched out the fit the flat rectangle. hope this helped
What is Alfred Wegener's hypothesis about the continents?
Alfred's hypothesis was that all the continents were a big land mass which he called Pangaea because if you see a world map it is like a jigsaw puzzle and other evidence is that some animal fossils were on other continents. Also the same rock range was found on different continents.
Continents grow through a process called continental drift, where tectonic plates move and collide. As plates converge, they can create mountain ranges and add landmass to existing continents. This process takes millions of years to occur.
What are the two continents in the world with the largest land areas?
Asia is the largest
Africa is the second largest
Which country is located at 60 degree north and 10 degree east?
The country located at 60 degrees north and 10 degrees east is Norway.
Swamp reclamation is the process of restoring or converting swampland into usable land for agriculture, infrastructure development, or other purposes. It typically involves draining, filling, or cultivating the swamp to make it suitable for human activities. Swamp reclamation is often necessary to expand arable land or address environmental concerns.
Where on earth would you find the greatest biodiversity?
In general, biodiversity globally is high in the Tropical World
of the humid tropics (most especially in tropical rainforests where more than half of all species are found) and in the extremely infertile Unenriched World
of the ancient arid landmasses of Australia and Southern Africa. Biodiversity is much lower in the geologically young and cool Enriched World
which basically corresponds to the extratropical northern and western hemispheres, plus New Zealand (which can very easily be thought of as part of the Western Hemisphere though it is on the other side of the International Date Line).
Although it is popularly though that high biodiversity relates to the more “benign†and less demanding environment in hot climates, recent research by Michael Huston of the University of Texas in “Biological diversity, soils, and economics†and “Precipitation, soils, NPP, and biodiversity: resurrection of Albrecht's curveâ€, Australian ecologist Tim Flannery in The Future Eaters
plus Jason Weir and Dolph Schluter in “The latitudinal gradient in recent speciation and extinction rates of birds and mammals†show that these are misconceptions.
Flannery and Huston both demonstrate that owing to the roughly four orders of magnitude greater age of their soils (except in the volcanic regions of the Pacific Rim), the productivity of the Tropical and Unenriched Worlds is very much less than those of the Enriched World of the extratropical northern and western hemispheres. Weir and Schluter show that speciation rates are much lower in the Tropical World than in the depauperate fauna of the Enriched. One would presume that with their extreme geological stability the Unenriched World of Australia and Southern Africa would have still lower speciation rates than the humid tropics
. This is especially true when one considers that many birds and mammals in Australia and Southern Africa require so much labour for reproduction that most adults must serve as “helpers at the nest†rather than reproduce on their own, which acts as an extremely severe limiter on potential dispersal.
All these indicators point to the higher diversity of the Tropical and Unenriched Worlds as being due to reduced interspecific competition
compared to the young and highly productive Enriched World. Soils of an infertility universal in all of the Unenriched and most of the Tropical World are exceedingly rare in the Enriched World - occurring only in a few areas of exceptionally nutrient-poor parent materials
like ultrabasic rocks (serpentines, peridotites) - and then only outside of glaciation limits within which intrazonal parent materials are converted to highly fertile zonal soils. (In this context, it’s notable that the most northerly major biodiversity hotspot in the Klamath Basin is one of the major occurrences of serpentines in the world, as is the very rich tropical hotspot of New Caledonia).
In the Tropical and Unenriched World resources are so scarce in unfertilised environments that co-operation rather than competition tends to be the rule to allow plants to obtain the minimal nutrition possible on these soils. The absence of competition reduces extinction rates to a fraction of the level observed throughout the Enriched World: in essence, the creation of biodiversity occurs in the Enriched World, but it is rapidly pooled into reservoirs in the Tropical World, and the Unenriched retains older species (marsupials, mousebirds) dating from periods when its ecological conditions were globally general.
What ecological region do Florida and Mexico share?
Florida and Mexico share the ecological region of the southeastern coastal plain, characterized by flat terrain, marshes, wetlands, and diverse flora and fauna that thrive in humid subtropical climates. Both regions have similar ecosystems supporting a variety of plant and animal species adapted to these environments.
Is California a functional region?
California is not typically considered a functional region as it does not exhibit the clear functional characteristics that define functional regions, such as a central hub providing a service or good to the surrounding areas. California is more commonly categorized as a formal region due to its clearly defined boundaries and characteristics.
Yes, Tsunami is a place as well as being a tidal wave within the continent of Asia.
How did the continents get to where they are today?
The Earth is made up of Tectonic Plates, these are large sections of land (Continental Plates) or ocean (Oceanic Plates). The Mantle (magma beneath the Earth's crust) is heated from the core of the Earth, where it is hottest, causing a convection current, this is when a fluid (magma in this case) is heated unevenly and the hot fluid rises, causing the cooler fluid to sink in its place (forming a circular current of heating, rising, cooling and sinking.)
This current effectively drags the Tectonic Plates along in differenbt directions to each other, causing them to move apart or together, sometimes even alongside each other.
What land masses are in the Arctic Circle?
The Arctic Circle includes parts of North America (Alaska in the United States and northern Canada), Europe (Norway, Sweden, Finland, Russia), and Asia (Russia). This region is characterized by cold temperatures, permafrost, and ice-covered seas.
What percent of the world is covered in asphalt?
Estimates suggest that around 1% of the Earth's land surface is covered by asphalt or other forms of impervious surfaces such as concrete. This percentage is expected to increase as urbanization and infrastructure development continue.
Brown.
Wow, that previous answer is SO wrong! Some of Utah's mountains rise to over 13,000 feet of elevation. Within Utah's SIX major life zones, over 4,000 floral species are recognized.
Of course From the lighter side; As a dedicated omnivore, I'd have to respond, "Delicious!"

Which continent is covered with snow?
A snowfall depends upon two things, their being moisture in the air, and the arrival of a cold weather front.
At the poles, there is very little moisture in the air, so polar snowfalls are light. In fact Antarctica is considered a desert in terms of precipitation.
At the equator; and at low altitudes; there may be lots of water in the air, but the arrival of a cold front would be unusual.
So it is in the temperate regions, perhaps slightly closer to the polar ones, that you would expect the heaviest snowfalls. And on land of course.
