The correct answer is - D. volcanic eruptions.
In recent studies and research about the water on our planet and how it came to be, the scientists managed to find new evidence that suggest that not only the comets and asteroids contributed to the existence of water on our planet, but also the volcanoes.
The volcanoes are actually releasing into the atmosphere the material from the deeper part of the Earth, the mantle layer. The mantle layer, as it turns out, has water in its rocks, so through the volcanic eruptions, that were much more and much bigger in the distant past, that water got released into the atmosphere. From the atmosphere, that water was falling on the surface, thus contributing to the creation of the first oceans on Earth.
The mass number of an element is equivalent to the number of Protons and Neutrons in the element. For example Oxygen has eight protons and neutrons, therefore its mass number is 16. You could also calculate this by simply rounding the atomic weight of the element to the nearest whole number. Oxygen's atomic weight is 15.994, which as you can see, would be rounded to 16 :)
Answer:Sphere A has a diameter of 12 and is dialated by a scale factor of 1/2 to create sphere B. What is the ratio of the volume of sphere A to sphere B? oh ok i know what is it A the second one is B
Explanation:
Answer:
<u>Danyang–Kunshan Grand Bridge</u>
The Lake Pontchartrain Causeway is the world's longest continuous bridge over water. The world's longest bridge is the Danyang–Kunshan Grand Bridge in China, part of the Beijing-Shanghai High-Speed Railway. The bridge, which opened in June 2011, spans 102.4 miles (165 kilometers).
second longest= Changhua–Kaohsiung Viaduct
Taiwan High Speed Rail
