The answer to your question is c because ecology is in fact the study of ecosystems; how organisms interact with their surroundings
When the sea floor spreads or collides it creates breakages which would be ocean ridges and deep sea trenches
Th e original sentence is correctly written. Th e giant fungus is described as an interwoven filigree spawned … some 10,000 years ago and extending for more than 30 acres. Th e present participle extending parallels the past participle spawned. A Correct. Th is sentence has the participles spawned and extending in a correct parallel construction. Spawned refers to something that happened in the past, while extending refers to something that continues into the present.
option A is the answer
"EXTENDING"
Answer:
Fires, volcanoes, and weathering
The atmosphere transfers heat energy and moisture across the Earth. Incoming solar radiation (insolation) is redistributed from areas in which there is a surplus of heat (the equator) to areas where there is a heat deficit (the North and South Pole). This is achieved through a series of atmospheric cells: the Hadley cell, the Ferrel cell and the Polar cell (Figure 2). These operate in a similar way to, and indeed interact with, the ocean conveyor.
For example, as the oceans at low latitudes are heated, water evaporates and is transported poleward as water vapour. This warm air eventually cools and subsides. Changes in temperature and CO2 concentrations can lead to: changes in the size of atmospheric cells (in particular, the Hadley cell is susceptible to these alterations); warming in the troposphere; and disproportionately strong warming in Arctic regions. The strong interactions between ocean and atmospheric dynamics, and the significant feedback mechanisms between them, mean that climate researchers must consider these Earth components as interlinked systems. The necessity to assess ocean-atmospheric changes at the global scale has implications for the way in which research is conducted. It is only by integrating palaeo evidence of past changes, with present day monitoring, and projected models,
