southern westerly winds submit to the enso regime: a multiproxy paleohydrology record from lake dobson, tasmania

Answers

Answer 1

Near its western shore, Tasmania is home to mountain ranges that run north to south. Due of this, places west of the Alps show a positive association between SWW flow and precipitation, whereas eastern regions either show no link or a negative one.

Why the Dobson lake is focus point?

Here, we provide data from charcoal, geochemical proxies, and chironomid remnants to examine the paleohydrological history of Lake Dobson, a site found in Tasmania's Mount Field National Park. The proxies identified three major time periods: (1) an early Holocene (11.5-8.3 cal kyr BP) characterized by generally high rainfall, the occurrence of irregular fires, and elevated charcoal influx at 11.4 and 10.2 cal kyr BP – conditions compatible with attenuated SWW flow over the site; (2) an ambiguous mid-Holocene (8.3-5 cal kyr BP) that marks the transition from a SWW- to EN The teleconnections between southern Australasia and the equatorial Pacific are highlighted by the proxy record of Lake Dobson.

Salt-affected soils reduce plant growth and limit crop production. Although salts can accumulate in almost any cropland soil, salt accumulation is especially problematic on croplands that are irrigated with groundwater and occur in arid and semi-arid environments.
Describe, in general, the salinization process in irrigated soils under semi-arid conditions.

Answers

Salinization in irrigated soils under semi-arid conditions occurs when salts accumulate within the soil profile due to the evaporation of water containing dissolved salts.

This phenomenon is more pronounced in regions with limited rainfall and high evaporation rates, such as arid and semi-arid areas.

The issue arises when the amount of water lost through evapotranspiration exceeds the water infiltrating the soil and draining out of the root zone.

Consequently, the application of irrigation water can lead to salt build-up in the soil profile since there isn't enough water to leach the salts beyond the root zone.

Over time, this gradual increase in soil salinity can result in soil degradation and reduced crop yields, posing limitations to agricultural productivity.

In summary, salinization in irrigated soils under semi-arid conditions stems from the accumulation of salts in the soil profile due to evaporation of irrigation water containing dissolved salts, ultimately leading to soil degradation and decreased crop productivity.

Why does the equatorward bending of height contours for the 500 mb level imply the presence of a trough?

Answers

The equatorward bending of height contours for the 500 mb level imply the presence of a trough because  this represents a region of overall lower heights. A valley and a trough are hence equivalent in the upper air flow.

A trough is a linear structural depression with lateral length that occurs in geology. A trough can be a small basin or a natural rift, albeit it is lower than a trench. At the edge of tectonic plates, these landforms frequently form.

Trough, an extended depression in the seafloor that differs from oceanic trenches in that it is shallower, shorter, narrower, and topographically more mild. The Papuan Trough's maximum depth is 2,300 m (7,500 feet), while the Banda Trough's maximum depth is 7,440 m.

where along a fault are you most likely to see a large earthquake?

Answers

You are most likely to see a large earthquake along the part of a fault known as the hypocenter or focus.

A fault refers to the boundary between two plates that are moving away from each other, toward each other, or past each other. As rocks shift past each other, they create seismic waves that cause earthquakes. The point on the Earth's surface directly above where the rocks break and shift is known as the epicenter, while the part of the fault where the rocks break is known as the hypocenter or focus.Large earthquakes are likely to occur along the hypocenter or focus of a fault. When a fault breaks, it releases energy in the form of seismic waves. This energy is what causes the ground to shake and leads to the occurrence of an earthquake. The amount of energy released during an earthquake is directly related to the size of the earthquake. Therefore, the larger the earthquake, the more likely it is to occur along the hypocenter or focus of the fault.

Well, first off, stars are all different. The reason some stars look different could be because of their color, the tempurature difference, and in some cases if the stars are using gas or rocks to fuel themselves.

The color of a star is linked to its surface temperature. So the hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.

Which condition makes it better to enter a port or beach during the daytime?.

Answers

Entering a port or beach during the daytime has various advantages over entering the same place during the night time.

The visibility during the daytime is one of the primary reasons why entering a port or beach during the daytime is better.In the day time, the pilot has better visibility. It becomes easier to identify the landmarks, buoys, and navigational aids with a clear view. This makes navigation relatively easy and helps in planning the entry and exit routes of the vessel safely.

 Furthermore, during the daytime, the daylight and sunshine aid the watchkeepers in monitoring the movements of other vessels in the vicinity. The chances of collision reduce in daylight, thereby minimizing the possibility of accidents or mishaps. Another advantage of daytime is that the winds are less strong.

During the day, the weather is usually calm, and the wind speed is lower compared to the night time. This helps in mooring, anchoring, and berthing of the vessel without much difficulty. During the night, the wind speed increases, making it challenging to berth and anchor the ship safely.

Therefore, entering a port or beach during the daytime is better than entering the same place during the night time.

Simple volcanoes with steep sides and a crater with a bowl-shaped summits are referred to as cinder cones. They hardly rise above a hill's height, which is about 1,000 feet. They normally form from eruptions from a single entry, unlike shield volcanoes and stratovolcanoes, which can erupt from multiple openings. Shield-shaped volcanoes are formed from a number of low-viscosity magmas. From the vent, magma rises to the surface, flows down the volcano's slopes, and increases in volume. Shield volcanoes earned their name because they resemble a warrior's shield lying on the ground.

Early urban areas in North America tended to develop along rivers. Thus option (A) is correct.

What is a river?

A river is a natural stream of water that flows or starts from its source until its mouth, where a river finally discharges its water. A river can discharge its water into another river, a lake or the sea.

A river can receive water from different sources: Precipitation or rainfall; Surface runoff; Springs and seepage water; water from snowmelt in areas with snow and glaciers.

In mountainous and hilly areas, rainwater flows and concentrates in lower areas, which fill up to form lakes.

When the river flows through lowlands, the channel will erode the outer banks of bends, depositing sediment and generating a flood plain. These flood plains are very fertile and the major cities progress along the rivers.
