The biggest threat for Mexico City is earthquakes - they are often caused by the nearby volcanoes, but the volcanoes are too far to truly threaten the city.
Monsoons are typical for other regions, such as India and Tornadoes are found more to the north, in the United States.
Biodiversity is the answer
Answer:
Most of the part of the plate disappeared due to the early tectonics events
Explanation:
- The pacific plate is the largest oceanic plate in the world and is 103 km square. The plate consists of Hawaiian islands and hot springs, the plate forms a convergent margin near the North American boundary.
- The movement of the pacific plate is towards the northwest and has a sped / velocity of 52-102 mm per year. The oldest part of the plate disappeared away by the plate tectonic cycle in the early cretaceous period.
Answer:
The statement is false.
Explanation:
Carbon dating using the radioactive decay of Carbon-14 is reliable up to 50,000 years. It is mostly used for living organisms that were younger than that period. Rocks are much older than 50,000 years and rocks from the Mesozoic era would not be able to be dated using Carbon-14. It will require another element with longer half-lives in order to determine ages higher than 65 million years ago.
Answer:
A. Cambrian explosion , Active plate margin, True.
Explanation:
- The burgess shale is a window into life on earth during the exposition of Canadian Rockies. Itis one of the earlier imprints containing the soft part imprints.
- Fossil deposits of burgess shale correlate to the Stephen formation. that were collected about 508 million years ago. Beds were deposited at the base of the cliffs 160 meters tall.
- North American plate is considered as an active plate margin, as this margin is moving westwards. And the pacific plate is shrinking in size. The presence of Icelandic Arcand festoons depicts this.
- The laptus ocean in the paleozoic era was an Icelandic volcano found in the ancient oceanic crust of ophiolites of Newfoundland. This ocean was earlier also named as the titan impetus.
