Sacramento Valley
The Sacramento Valley is the area of the Central Valley of the U.S. state of California that lies north of the Sacramento–San Joaquin River Delta and is drained by the Sacramento River. It encompasses all or parts of ten Northern California counties. Although many areas of the Sacramento Valley are rural, it contains several urban areas, including the state capital, Sacramento. Comparatively water-rich relative to the other segment of the Central Valley to the south, the San Joaquin Valley, there are slight differences in the crops typically grown in the Sacramento Valley. Much wetter winters (averaging between of annual precipitation in the nearby foothills) and an extensive system of irrigation canals allows for the economic viability of water-thirsty crops such as rice and '' Juglans hindsii''-rootstock walnuts. Since 2010, statewide droughts in California (combined with unprecedented summer heat) have strained both the Sacramento Valley's and the Sacramento metropolitan ...

Sierra Nevada (U
The Sierra Nevada ( ) is a mountain range in the Western United States, between the Central Valley (California), Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south, and its width ranges from to across east–west. Notable features include the General Sherman Tree, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing List of waterfalls in Yosemite National Park, high waterfalls. The Sierra is home to three national parks, twenty-six wilderness areas, ten national forests, and two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Security
The aim of water security is to maximize the benefits of water for humans and ecosystems. The second aim is to limit the risks of destructive impacts of water to an acceptable level. These risks include too much water (flood), too little water (drought and water scarcity), and poor quality ( polluted) water. People who live with a high level of water security always have access to "an acceptable quantity and quality of water for health, livelihood, and production". For example, access to water, sanitation, and hygiene services is one part of water security. Some organizations use the term ''"water security"'' more narrowly, referring only to water supply aspects. Decision makers and water managers aim to reach water security goals that address multiple concerns. These outcomes can include increasing economic and social well-being while reducing risks tied to water. There are linkages and trade-offs between the different outcomes.REACH (2020REACH Global Strategy 2020-2024 Univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

Sutter Buttes
The Sutter Buttes (Maiduan languages, Maidu: ''Histum Yani'' or ''Esto Yamani'', Wintuan languages, Wintun: ''Olonai-Tol'', Nisenan language, Nisenan: ''Estom Yanim'') are a small circular complex of eroded volcanic lava domes which rise as buttes above the flat plains of the Sacramento Valley in Sutter County, California, Sutter County, northern California. They are situated just outside Yuba City, California, Yuba City in the northern part of the state's Central Valley (California), Central Valley. These remnants of a dormant volcano are colloquially referred to as the world's smallest mountain range. The Sutter Buttes have as their highest point the summit of South Butte, at , which is also the highest point in Sutter County. Land was designated as a state park in 2003 after the California State Park system acquired property on the North of the buttes. It has yet to be named officially and is not open to the public as the appropriate classification of park resources is still ...

California Gold Rush
The California gold rush (1848–1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to grow rapidly into statehood in the Compromise of 1850. The gold rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation, and the California genocide. The effects of the gold rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, nicknamed "forty-niners" (referring to 1849, the peak year for gold rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii), and Latin America in late 1848. Of the approx ...

Rain Shadow
A rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side. Evaporated moisture from body of water, bodies of water (such as oceans and large lakes) is carried by the prevailing sea breeze, onshore breezes towards the drier and hotter inland areas. When encountering elevated landforms, the moist air is orographic lift, driven upslope towards the summit, peak, where it expands, cools, and its moisture condenses and starts to Precipitation, precipitate. If the landforms are tall and wide enough, most of the humidity will be lost to precipitation over the windward side (also known as the ''rainward'' side) before ever making it past the top. As the air descends the leeward side of the landforms, it is compressed and heated, producing Foehn winds that ''absorb'' moisture downslope and cast a broad "shadow" of arid, dry climate region behind the ridge, mountain crests. This climate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."

Valley
A valley is an elongated low area often running between hills or mountains and typically containing a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally ...
