Answer:

Option (3)

Explanation:

Rhyolitic magma is the most viscous and rhyolite is the volcanic equivalent of granite. In the case of Rhyolitic magma, the silica content is more than 65%. This type of magma generally forms because of the wet melting of continental crust. This magma when traps gas in it or it comes in contact with water, then it becomes highly explosive and violent, producing a large amount of pyroclastic materials. It leads to the production of rocks such as Pumice along with other ash deposits.

Thus, the Rhyolitic type of magma is highly viscous.

Thus, the correct answer is option (3).

This question is probably from Oddessyware or QDA I just had the same question. The answer is rhyolitic because it is high in viscous, Silica content, gas content, and explosiveness.

Alex17521 [72]

Answer:

Induced climate change and its effects will proceed for a long time, and at times for a long time. Separately and by and large, and in blend with the impacts of other human exercises, these progressions posture dangers for a broad scope of social and ecological frameworks, including freshwater resources, the seaside condition, environments, farming, fisheries, social wellbeing, and national security, among others.

Earth’s physical climate framework, which incorporates the environment, seas, cry sphere, and land surface, is mind-boggling and always advancing.

Why would you expect that seafloor samples taken farther from land usually contain a greater proportion of biogenous sediments t

Natali [406]

It is expected that seafloor samples taken farther from land usually contain a greater proportion of biogenous sediments because sediments are thinnest on the seabed closest to spreading centres (young seafloor) and thicker distant from the ridge (older seafloor with more time for accumulation). Additionally, sediments are substantially thicker close to continents.

More about seafloor sediments:

Terrigenous, pelagic, and hydrogenous sediment are the three different types of sea floor sediment. Terrigenous sediment is deposited on the continental shelf, continental rise, and abyssal plain and is derived from the land.

Clay particles and tiny marine animal skeletons that progressively sink to the ocean floor make up pelagic sediment. Minerals that precipitate from seawater on the ocean floor, such as manganese nodules, are abundant in hydrogenous sediments.
