GNA - The Two Californias

Image
Map of the Californias - by Me The Californias include mainland California and the island of Baja California. The mainland is composed for the temperature lands surrounding the Sacramento bay and the mountains which ring it - the Klamath mountains to the northwest, Sierra Madre to the east, and the San Gabriel and San Bernardino mountains to the south. These southern mountains as split in half by the San Andreas Straight, with one half of both ranges remaining on the mainland and the other forming the northernmost portion of the island of Baja California, beyond which is desert. Monterey Coast - Guy Rose The climate of mainland California is semi-arid Mediterranean with mild, wet winters and dry, hot summers. The average temperature in summer is 30 C while in winter it is about 20 C. Temperatures tend toward mild on the pacific coast and along the Sacramento Bay. Meanwhile, at high elevations like the southern mountains, summer temperatures become more varied and cooler in general, as ...

GNA - Arctic Archipelago

Image
Map of the Arctic Islands - by Me The harshest environment of North America, this region includes all of the non-tree baring islands of the Arctic ocean. Once covered in permafrost, which helped to trap moisture in the ground, the warmer southern months have allowed this water to escape turning it into a frigid desert. Its flora, where it occurs, consists mostly of herbs, lichen, and dwarf shrubs Pangnirtung Fjord, Auyuittuq National Park, Baffin Island - Ruth Driedger The Arctic archipelago has a frigid semi-arid climate with short, cool summers and long, cold winters. Average daily temperatures in the summer are 10 C while in winter they average less than -30 C. Annual precipitation ranged from about 300mm to 500mm. Highlands, mostly bare rock, are unable to hold water and so it tends to pool in low-lying lakes, rivers, and muskegs. Most characteristic of the climate of the far north is the immense seasonal fluctuation in the length of daylight. In the warmest months the sun can stay...

GNA - Ecology of the Subtropic East

Image
Map of the Tropical East - by Me This region of mixed forest is bounded in the west by the Mississippi river and the east by the vast reaches of the Atlantic ocean. Its northern boundaries are the St Lawrence and the Great Lakes, except for the northern portion of the Appalachians which are instead part of the northern forests. In the South, the forests continue into the Mississippi and Mexican gulfs along numerous peninsulas and islands Tropical Landscape - Frederick Church The climate is humid, tropical in the south abut more temperate to the north along the Great Lakes and St Lawrence. Higher elevations such as the Appalachian and Ozark mountains have mild oceanic climates. Throughout the region seasons are well defined, with hot summers and cool winters. Snowfall occurs regularly only the northernmost regions and only then in the coldest months - with the Maritimes being frost free year round due to the moderating influence of the ocean. Weather can be unpredictable across the regi...
