World War I and II. These wars caused lots of economic growth and development because there was a pressure to create better inventions. Having better technology could mean the win or lose of a war. :D
Answer:
D. A substance, energy source, or organism used by humans
Explanation:
Its not man made like the others
Answer:
The upper layer of the mantle is said to be thicker than the lower mantle, but not solid rock like crust. The tectonic plates rest on this layer and it is responsible for the movement of those plates.
Explanation:
hope this helps if it doesn't sorry
True, The biomass of cultivated land around equals the biomass of temperate grassland.
According to this graph, algal beds and coral reefs have the most increased net primary productivity. The net primary productivity of an estuary ecosystem is around 12 times the net prior productivity of the open ocean.
<h3>What is the biomass of a plant?</h3>
Plant biomass (W) is the weight of living plant material included above and below a unit of ground surface area at a provided point in time. Production is the biomass or weight of organic matter incorporated by a society or species per unit land area per unit time.
<h3>What is biomass presentation in crops?</h3>
Biomass is emanated from organic material such as trees, plants, and agricultural and urban waste. The prevalence of biomass produced by EU agriculture comes in the formation of biogas, and feedstocks for making biodiesel and bioethanol.

On the West coast of North America, the coast ranges and the coastal plain form the margin. Most of the land is made of terranes that have been accreted onto the margin. In the north, the insular belt is an accreted terrane, forming the margin. This belt extends from the Wrangellia Terrane in Alaska to the Chilliwack group of Canada.
A rupture in Rodinia 750 million years ago formed a passive margin in the eastern Pacific Northwest. The breakup of Pangea 200 million years ago began the westward movement of the North American plate, creating an active margin on the western continent. As the continent drifted West, terranes were accreted onto the west coast. The timing of the accretion of the insular belt is uncertain, although the closure did not occur until at least 115 million years ago.Other Mesozoic terranes that accreted onto the continent include the Klamath Mountains, the Sierra Nevada, and the Guerrero super-terrane of western Mexico.80 to 90 million years ago the subducting Farallon plate split and formed the Kula Plate to the North. This formed an area in what is now Northern California, where the plates converged forming a Mélange. North of this was the Columbia Embayment, where the continental margin was east of the surrounding areas.Many of the major batholiths date from the late Cretaceous. As the Laramide Orogeny ended around 48 million years ago, the accretion of the Siletzia terrane began in the Pacific Northwest. This began the volcanic activity in the Cascadia subduction zone, forming the modern Cascade Range, and lasted into the Miocene. Events here may relate to the ignimbrite flare-up of the southern Basin and Range. As extension in the Basin and Range Province slowed by a change in North American Plate movement circa 7 to 8 Million years ago, rifting began on the Gulf of California.
