hurricanes are more common in florida than california because of the warmer water temperatures and prevailing wind direction. group of answer choices true false

Answers

The statement “Hurricanes are more common in Florida than in California because of the warm water and strong winds is true because Warm water temperatures in the Atlantic and Gulf of Mexico provide the energy needed to form and intensify hurricanes.

Hurricanes are actually more common in Florida than in California, due to the combination of warmer water temperatures and prevailing wind direction.  Water temperatures above 80°F (26.5°C) create favorable conditions for tropical cyclones.

In addition, the prevailing wind pattern plays an important role. In Florida, prevailing winds known as trade winds blow across the Atlantic from east to west. These winds help carry tropical disturbances and storms from the warm waters of the Caribbean or Atlantic to Florida, increasing the likelihood of hurricane formation and landfall in the state.

what type of deposit consists of glacial rock flour from blowing winds?

Answers

Glacial rock flour deposits formed by blowing winds are known as loess deposits. These deposits are characterized by fine, silt-sized particles that have been ground down by glaciers and transported by the wind over long distances.

Loess deposits are primarily composed of mineral particles derived from the grinding action of glaciers on underlying rocks during periods of glaciation. As glaciers move, they scrape against the bedrock, grinding it into fine particles known as rock flour. When the ice eventually melts, these rock flour particles are left behind as deposits. Over time, the deposits can be redistributed by wind, resulting in extensive layers of loess.

The transportation and deposition of loess can occur over vast distances. Wind carries the fine particles and deposits them in areas with favorable conditions, such as large open plains or downwind of glacial sources. These deposits often form thick layers of sediment, which are highly fertile and can support agriculture. Loess deposits are found in various parts of the world, including regions in North America, Europe, Asia, and New Zealand. Their unique characteristics make them important for understanding past climatic conditions and studying ancient civilizations that relied on loess for agricultural purposes.

define fertility management​

Answers

Answer:

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact.
Advancing food security and environmental sustainability in farming systems requires an integrated soil fertility management approach that maximizes crop production while minimizing the mining of soil nutrient reserves and the degradation of the physical and chemical properties of soil that can lead to land degradation, including soil erosion. Such soil fertility management practices include the use of fertilizers, organic inputs, crop rotation with legumes and the use of improved germplasm, combined with the knowledge on how to adapt these practices to local conditions.

The Joint FAO/IAEA Division assists Member States in developing and adopting nuclear-based technologies for improving soil fertility practices, thereby supporting the intensification of crop production and the preservation of natural resources.
Different approaches to efficiently manage soil fertility
An integrated soil fertility management aims at maximizing the efficiency of the agronomic use of nutrients and improving crop productivity. This can be achieved through the use of grain legumes, which enhance soil fertility through biological nitrogen fixation, and the application of chemical fertilizers.

Whether grown as pulses for grain, as green manure, as pastures or as the tree components of agro-forestry systems, a key value of leguminous crops lies in their ability to fix atmospheric nitrogen, which helps reduce the use of commercial nitrogen fertilizer and enhances soil fertility. Nitrogen-fixing legumes are the basis for sustainable farming systems that incorporate integrated nutrient management. Use of nitrogen-15 lends understanding of the dynamics and interactions between various pools in agricultural systems, including nitrogen fixation by legumes and utilization of soil and fertilizer nitrogen by crops, both in sole and mixed cropping systems.

Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose fertilizer applications, to replenish losses through plant uptake and other processes; and by minimizing losses through leaching below the crop rooting zone by improved water and nutrient application.
The contribution of nuclear and isotopic techniques
The isotopes of nitrogen-15 and phosphorous-32 are used to trace the movements of labelled nitrogen and phosphorous fertilizers in soils, crops and water, providing quantitative data on the efficiency of use, movement, residual effects and transformation of these fertilizers. Such information is valuable in the design of improved fertilizer application strategies. The nitrogen-15 isotopic technique is also used to quantify the amount of nitrogen fixed from the atmosphere through biological nitrogen fixation by leguminous crops.

The carbon-13 isotope signature helps quantify crop residue incorporation for soil stabilization and fertility enhancement. This technique can also assess the effects of conservation measures, such as crop residue incorporation on soil moisture and soil quality. This information allows the identification of the origin and relative contribution of different types of crops to soil organic matter.

How would stream deposits differ from glacial deposits?

Answers

Answer:

Sediments transported and deposited during the Pleistocene glaciations are abundant throughout Canada. They are important sources of construction materials and are valuable as reservoirs for groundwater. Because they are almost all unconsolidated, they have significant implications for mass wasting.

The Bering Glacier is the largest in North America, and although most of it is in Alaska, it flows from an icefield that extends into southwestern Yukon. The surface of the ice is partially, or in some cases completely, covered with rocky debris that has fallen from surrounding steep rock faces. There are muddy rivers issuing from the glacier in several locations, depositing sediment on land, into Vitus Lake, and directly into the ocean. There are dirty icebergs shedding their sediment into the lake. And, not visible in this view, there are sediments being moved along beneath the ice.

Explanation:

Subglacial sediment (e.g., lodgement till) is material that has been eroded from the underlying rock by the ice, and is moved by the ice. It has a wide range of grain sizes, including a relatively high proportion of silt and clay. The larger clasts (pebbles to boulders in size) tend to become partly rounded by abrasion. When a glacier eventually melts, the lodgement till is exposed as a sheet of well-compacted sediment ranging from several centimetres to many metres in thickness. Lodgement till is normally unbedded. An example is shown in Figure 16.31a.

Supraglacial sediments are primarily derived from freeze-thaw eroded material that has fallen onto the ice from rocky slopes above. These sediments form lateral moraines (Figure 16.1) and, where two glaciers meet, medial moraines. (Medial moraines are visible on the Aletsch Glacier in Figure 16.22.) Most of this material is deposited on the ground when the ice melts, and is therefore called ablation till, a mixture of fine and coarse angular rock fragments, with much less sand, silt, and clay than lodgement till. An example is shown in Figure 16.31b. When supraglacial sediments become incorporated into the body of the glacier, they are known as englacial sediments
