<span>Being one of the greatest mountain range, Himalayas divide mainland China from the Middle East, separating the plains of the Indian subcontinent from the elevated plateau in Central and East Asia. It’s highest peak is placed between Nepal and China which is called Mount Everest - Earth's highest mountain. According to its dimension and the areas which this structure embraces, Himalayas are one of the physical features that keep China as an isolated country.
The Japanese archipelago consists of 6,852 islands but some of them (because of close geographical position and small dimension) are united so that you usually may come across the couple of islands that defined as a whole one. Due to this fact, the most suitable approximate number for this case is 3000, as most of the previous number contains small and inhabited islands.
The climate of Gobi Desert is famous for its rapid and incredible changes of temperature during seasons. These changes are caused by wind blowing from the Siberian Steppes that makes this cold desert totally extreme. The temperature on Gobi ranges from −40 °C or −40 °F in winter to 45 °C or 113 °F in summer. The most unbelievable thing is that this temperature can vary within twenty four hours instead of seasonal periods. So the is 'Extremely cold winters and blistering hot summers'.
Japan is the island nation in Eastern Asia that embraces nearly 6850 islands forming the country. This huge archipelago consists of wide range of small islands including four main ones, which are : Hokkaido,
Honshu, Shikoku, Kyushu. Honshu is the the largest island where the capital city is situated.

At this point, i think you can allow the line to miss a plot a little bit when passes between circles
pretty much it would look like this ,
just crosscheck it with the data if you're not sure
Hope this helps
Answer:
B. Aerobic bottom water
D. High organic productivity in the overlying oxygen rich water
Explanation:
A Shale is a sedimentary rock usually formed from silt and clay-size mineral. There are different colors of Shale. The Black Shale is formed under anaerobic conditions. This means that oxygen is deficient in the water where the Shale forms.
A little amount of organic materials is required for the formation of Black Shale and because Black Shale is formed in an environment lacking oxygen, an oxygen-rich water would not be necessary for its growth. Sediments are necessary in the formation of Black Shale.
Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
