Answer:
A.) A warm ocean current flows along the coast
Explanation:
The sea ports which remain ice-free are called "warm-water ports." Other than those that can be found in Europe, warm-water ports can also be found in <em>New York</em> and <em>Canada.</em> This is due to the<u> warm ocean current that flows along the coast in these areas</u>. This allows the area to be free from ice, thus ships can just come and go. It is said that the "Gulf Stream" is responsible for bringing the warm water to Europe. However, other countries have cold-water ports just like in Russia.
Sediment on the seafloor originates from a variety of sources, including <span>biota </span><span>from the overlying ocean water, </span>eroded<span> material from land transported to the ocean by rivers or wind, ash from volcanoes, and chemical </span><span>precipitates </span><span>derived directly from sea water. A very small amount of it even originates as </span><span>interstellar </span>dust. In short, the particles found in sediment on the seafloor vary considerably in composition and record a complex interplay of processes that have acted to form, transport, and preserve them.<span>

Rainfall is the most important single factor in determining whether runoff will or will not occur for a given set of environmental conditions. It determines runoff amount and frequency. There are two measurements of rainfall amount that are commonly collected for hydrological purposes: Daily and (runoff) Event rainfall.
Daily Rainfall is probably the most ubiquitously measured meteorological variable. It is the rain that falls awing a 24 how period starting in the morning of one day (commonly 06:00, 07:00 or 08:00 furs) until measurement is made at the same time the following day. Event Rainfall by contrast is the rainfall occurring awing an unspecified time period usually, but not always less than 24 hours, that can be seen to be responsible for subsequent runoff. The collection and use of each has advantages and disadvantages.
In the case of daily rainfall, data are usually available from many stations, even in countries with only the most basic meteorological network. The equipment to measure daily rainfall is relatively cheap, simple to install, read and maintain. All projects should easily achieve adequate instrumentation. In most cases, many years of historical data will be available for analysis from a variety of sources, in addition to that obtained from meteorological offices: these sources include various government departments, water resource and construction projects, state and private farms, schools and interested individuals. Often basic analyses will have been performed on the data (average monthly and annual totals, spatial distribution, etc.). For the analysis of runoff relations, however, daily rainfall can have one serious drawback. It is the lump sum rainfall awing a 24 how period and in some climatic environments may greatly exaggerate the amount of rainfall thought to be responsible for runoff, but despite this drawback, it is the most commonly used climatic variable in runoff studies.
Event rainfall, obtained from the careful examination of the records of an automatically recording rain gauge, can provide a precise and accurate evaluation of the rainfall responsible for runoff and it is often to be preferred for rainfall/runoff analyses. However, recording rain gauges are not usually in widespread use except at important synoptic stations (especially in developing countries). They are expensive to buy, can be difficult to maintain and staff must have a higher level of expertise to operate them. The analysis of data is more complex and time-consuming.
Answer:
90 units in Length and 6 units wide
Explanation:
First find. Square footage by: 450 x 30 = 13500 sq. feet
Divide: 13500 ÷5 = 2700
So every unit equals 2700. square feet.
1 unit = 5 feet.
÷ 450 ÷ 5 = 90 units in length and 30 ÷ 5 = 6 units wude
Answer:
Erie Canal
Explanation:
The building of 'Erie Canal' in the east-west part of the Newyork city was the key reason for stimulating 'a wave of canal building across the country' as it proved to be a great source of promoting both the agricultural as well commercial development of the state by directly bringing water to the Midwest. It helped in evolving New York as the commercial city of the United States.
