The latitudinal circulation can also act on this scale of oceans and continents, and this effect is seasonal or even decadal. Warm air rises over the equatorial, continental, and western Pacific Ocean regions. When it reaches the tropopause, it cools and subsides in a region of relatively cooler water mass.
Continents affect the climate of the planet drastically, with supercontinents having a larger, more prevalent influence. Continents modify global wind patterns, control ocean current paths, and have a higher albedo than the oceans. [1] Winds are redirected by mountains, and albedo differences cause shifts in onshore winds.
A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations including both deletion and non-deletion forms.
Below are separate lists of countries and dependencies with their land boundaries, and lists of which countries and dependencies border oceans and major seas. The first short section describes the borders or edges of continents and oceans/major seas. Disputed areas are not considered.
Great Pacific garbage patch in August 2015 (model) The patch is created in the gyre of the North Pacific Subtropical Convergence Zone. The Great Pacific garbage patch (also Pacific trash vortex and North Pacific garbage patch [1]) is a garbage patch, a gyre of marine debris particles, in the central North Pacific Ocean.
None of the regions indicated on the map have sharp well-defined borders, except where the Escarpment, or a range of mountains forms a clear dividing line between two regions. The central plateau (apart from the Lesotho Highlands) forms a largely flat, tilted surface which, as indicated above, is highest in the east, sloping gently downwards to ...
In 1525, Spanish navigator Francisco de Hoces discovered the Drake Passage while sailing south from the entrance of the Strait of Magellan. [2] Because of this, the Drake Passage is referred to as the "Mar de Hoces (Sea of Hoces)" in Spanish maps and sources, while almost always in the rest of the Spanish-speaking countries it is mostly known as “Pasaje de Drake” (Argentina, mainly ...
Oceania with its sovereign states and dependent territories within the subregions Australasia, Melanesia, Micronesia, and Polynesia. Definitions of Oceania vary. [20] [21] [6] The broadest definition encompasses the many islands between mainland Asia and the Americas.
