Question

6 multiple choice 1 point which of the following processes usually takes the longest amount of time? hot lava cools and forms new rock. water vapor condenses to form a cloud. a seismic wave travels through the mantle. an ocean basin forms between two continents. 7 multiple choice 1 point which two tectonic plates are separated by a mid - ocean ridge? indian - australian and eurasian indian - australian and pacific north american and south american north american and eurasian

Explanation:

• For question 6:
• The formation of an ocean basin between two continents is a geological process that occurs over millions of years due to plate tectonics.
• Hot lava cooling to form new rock (igneous rock formation) can happen relatively quickly, from days to years depending on the lava flow size.
• Water vapor condensing to form a cloud is a meteorological process that occurs in a short time (minutes to hours).
• A seismic wave traveling through the mantle is an almost instantaneous process (as seismic waves travel at high speeds, though the distance they cover in the mantle can take some time, it is still much shorter compared to ocean - basin formation).
• For question 7:
• The North American and Eurasian plates are separated by the Mid - Atlantic Ridge, which is a mid - ocean ridge.
• The Indian - Australian and Eurasian plates have a convergent boundary (the Himalayas are formed due to this collision).
• The Indian - Australian and Pacific plates have a complex boundary with some transform and convergent aspects.
• The North American and South American plates are adjacent but not separated by a mid - ocean ridge in the traditional sense as they are part of the American plate complex (though there are some smaller scale tectonic features between them, not a major mid - ocean ridge like the Mid - Atlantic Ridge).

Answer:

1. An ocean basin forms between two continents.
2. North American and Eurasian.
