About every 50,000 years, the Earth's magnetic poles flip. As basalt emerges from the ocean floor due to seafloor spreading, the iron within it aligns according to the magnetic pole's position. Paleomagnetism is the study of this magnetic orientation in ancient rocks. So, if you examine a section of seafloor and identify three areas that show magnetic pole reversals, you can determine that approximately 150,000 years have elapsed based on the frequency of those reversals.
Response:
Point A is positioned at an elevation of 7000 feet. The symbol representing point B indicates a picnic area, with point B's elevation noted as 6800 feet.
The outermost layer of Earth (apart from the atmosphere) is the crust, which consists of moving tectonic plates. When these plates grind and collide, they create folds and uplift that form mountain ranges, and they cause continents to shift position. These processes occur over millions of years.
I previously responded affirmatively, confirming that quartz, for instance, has a hexagonal crystal structure and exhibits a prismatic form but lacks cleavage. Therefore, quartz serves as a prime example supporting this concept.
1) Based on the graph, the saturation vapor pressure is determined to be
23.4mb
2) In the art gallery when the relative humidity fell to 26%, the vapor pressure is calculated as
RH = (VP/SVP)*100 26 (VP/23.4) *100 = 6.084
3) The dewpoint temperature in the art gallery when the relative humidity dropped to 26% is calculated as
Td= 68- ((100-26)/5) = 53.2
B)
It increases by 45%
