The most appropriate answer would be magma. Lava is a magma that reaches the Earth's surface, which is technically it is also a magma, and magma is located below the Earth's surface.
Lava at Earth's surface or magma below Earth's surface cools and harden to form mineral crystals.
<span>Trophic levels refer to where organisms fall on the food chain. Fish from higher trophic levels are often larger and have a higher dollar value at market, resulting in overfishing and the depletion of those species from the wild. If those fish are continued to be consumed at a high level, the loss of predators at the top of the food chain could throw off the balance in the ecosystem.</span>
<span>When there is no air movement, the relationship
between the intrapulmonary and atmospheric pressure is that they are equal. In
the start of a respiratory cycle, as the air is not moving, intrapulmonary and
atmospheric pressure are equal. Inhalation only started with the intrapleural
pressure falls off that in return helps with the enlargement of the thoracic
cavity.</span>
