Which coastal location experiences a cooler summer climate due to ocean currents?

Answers

Answer:

Northwest coast of Europe

Explanation:

The Northwest coast of Europe, that stretches from Northern France, to the Low Countries, to the west of the Scandinavian Peninsula (essentially Norway), including the British Isles (Britain, and Ireland), has remarkably cool summers, that are often rainy and windy. This is due to not only the northerly location of the region, but also because of the influence of the Atlantic Ocean, and its regional subdivisions like the Irish Sea, the North Sea, and the English Channel.

The ocean currents make winters less cold that in continental regions, and they also make summers cooler than in continental regions. In other worlds, ocean currents make climate milder as a whole, and that is why coastal regions have a less extreme climate than inland regions.

Check all that apply.
A. Military power
B. Standard of living
C. Life expectancy
D. Knowledge of the population through education and reading

Answers

Answer:

d

Explanation:

The HDI is calculated as the geometric mean (equally-weighted) of life expectancy, education, and GNI per capita, as follows: The education dimension is the arithmetic mean of the two education indices (mean years of schooling and expected years of schooling).

The factors determine a nation's human development index (HDI)

B. Standard of living

C. Life expectancy

D. Knowledge of the population through education and reading.

What is the human development index?

Average life expectancy at birth, educational attainment, and economic output measured by Gross National Product (GNP) per capita are all components of health that are reflected in the HDI.

In the interest of assessing three factors that have an impact on human development, the HDI is determined using an equation that integrates the three measures of life expectancy.

Government and relief organizations can use it as a means of determining where assistance is required and the effectiveness of their efforts to enhance conditions for human flourishing.

In Earth's current orbit, it is 1.52 x 1011 meters from the Sun at aphelion and 1.47 x 1011 meters at perihelion. Using these
values and the equation given in part A, what is the eccentricity of Earth's current orbit? Round your answer to three
decimal places. Consult the math review for help with scientific notation.

Answers

Answer:

0.017 is the right answer from accurate calculation, pls mark me branliest

Based on the calculations, the eccentricity of Earth's current orbit is equal to 0.017.

Given the following data:

Distance A = 1.52 × 10¹¹

Distance P = 1.47 × 10¹¹

How to calculate the eccentricity of Earth's orbit.

Mathematically, the eccentricity of Earth's current orbit would be calculated by using this equation:

[tex]e=\frac{a\;-\;p}{a\;+\;p}[/tex]

Where:

a is the radius at aphelion (apoapsis).p is the radius at perihelion (periapsis).e is the eccentricity of Earth's orbit.

Substituting the given parameters into the formula, we have;

[tex]e=\frac{1.52 \times 10^{11}\;-\;1.47 \times 10^{11}}{1.52 \times 10^{11}\;+\;1.47 \times 10^{11}}\\\\e=\frac{5 \times 10^9}{2.99 \times 10^{11}}[/tex]

e = 0.017.

How have different empires shaped the eastern Mediterranean regio?

Answers

At its greatest extent, the Arab Empire controlled 3/4 of the Mediterranean region, the only other empire besides the Roman Empire to control most of the Mediterranean Sea. The Mediterranean Sea was important to the Roman Empire in that it was a vital trade link with other parts of the Empire, especially the Middle East and North Africa. As Rome grew, it needed the grains and other food from the Levant, and African animals were considered status symbols in the Roman royal courts.


Today, the tallest mountain in the Appalachian Mountains is about 2,000 meters in elevation, while the tallest peaks
in the Rocky Mountains reach up to about 4,400 meters in elevation.
Explain how the Appalachian Mountains were formed and how they have become so much smaller over time.

Answers

Explanation:

Streams carried rock debris downslope to be deposited in nearby lowlands. The Taconic Orogeny was just the first of a series of mountain building plate collisions that contributed to the formation of the Appalachians, culminating in the collision of North America and Africa

The Appalachian Mountains become so much smaller over time due to the various geological processes that have contributed to their erosion and gradual diminishment over time.

The Appalachian Mountains were formed around 480 million years ago during a period of intense geological activity known as the Appalachian orogeny. During this time, tectonic plates collided, causing the earth's crust to fold and fault, and creating a mountain chain.

Over time, the erosion from weather and water has gradually worn down the mountains, reducing their height and size.

Answers

Answer:

B. 55°

Explanation:

Given:

m(WY) = 110°

m(YZ) = 160°

m(ZW) = 90°

Required:

m<WZY

Solution:

<WZY is an inscribed angle of the circle with intercepted arc WY.

The Inscribed Angle Theorem states that the measure of an inscribed angle = ½ of the intercepts arc measure

Therefore:

m<WZY = ½(WY)

Plug in the value

m<WZY = ½(110°)

m<WZY = 55°
