what kind of climate or climate would you likely find in western Scandinavia in the northern part of the United Kingdom word not for the north Atlantic current? why?

Answers

Answer:

Hi! I think your answer is...

Northern Region's climate is classified as tropical. In winter, there is much less rainfall in Northern Region than in summer.

Have a Good day or Night :D

The northwest of Europe has a cool temperate continental climate, also known as a Siberian climate. This region experiences lengthy, harsh winters and a short, cold summer that lasts just three to four months. There is a lot of snowfall in the winter.

Why do most of northwestern Europe have a generally mild climate?

The Gulf Stream, which warms the North Atlantic Current and comes from the Caribbean's tropical waters, is what makes the weather generally moderate. Weather pattern variations are a result of local winds.

There are subtropical humid marine climates, Mediterranean climates, semi-arid regions, highland climates, and maritime climates throughout Western Europe. Mostly semiarid, humid continental, and Mediterranean climates can be found in Southeast Europe. Northeast Europe has a humid continental, tundra, subarctic, maritime, and arctic climates.

Which of the following types of questions could be answered with some kind of distribution map? Check all that apply. O A. What is the average age of people in a given area? O B. What are the features of the Earth's crust? O C. How much money do people make in a particular area? D. Where are people literate or illiterate?​

Answers

Answer:

D

Explanation:

A distribution map can display the literacy rates across different regions, indicating areas with higher or lower literacy rates, thereby highlighting education disparities or patterns. Hence option D is correct.

A. What is the average age of people in a given area? A distribution map could depict the age demographics of different regions, showing the variation in average age across the area of interest.

C. How much money do people make in a particular area? A distribution map can illustrate the income levels or income brackets across different geographical regions, providing insights into the economic disparities or patterns in the area.

D. Where are people literate or illiterate? A distribution map can display the literacy rates across different regions, indicating areas with higher or lower literacy rates, thereby highlighting education disparities or patterns.

These questions require visualizing and understanding spatial patterns or variations, which can be effectively represented through distribution maps, enabling easier interpretation and comparison of data across different geographical locations.

B. What are the features of the Earth's crust? This question does not directly pertain to spatial distribution and is more related to geological characteristics. While maps can represent geological features, such as faults or mountain ranges, they may not necessarily convey distribution patterns in the same way as the other questions.

two numbers have a difference if 1200 and a total of 6484​

Answers

x + y = 6484
x - y = 1200
x = 6484 - y
6484 - y - y = 1200
5284 = 2y
y = 2642

x - 2642 = 1200
x = 3842

2642 and 3842

We have that the two number are
