The Earth's outer core is liquid, but it is liquid metal, not rock. [257] The Amazon rainforest does not provide 20% of Earth's oxygen. This is a misinterpretation of a 2010 study which found that approximately 34% of photosynthesis by terrestrial plants occurs in tropical rainforests (so the Amazon rainforest would account for approximately ...
For now, the spaces in the sponge aren't full enough of magma to support an eruption. For that to happen, the system would need more magma to fill more spaces in the crust's "sponge."

Earth has a lot of water. It’s almost like we’re hoarding the stuff for a not so rainy day. All of that water is more or less the defining feature of our planet when seen from a distance, but ...
Even earlier sponge-like fossils have been reported in reefs dating back to 890 million years before the present, but their identity is highly debated. [6] This dating is consistent with molecular data recovered through genetic studies on modern metazoan species; more recent studies have concluded that the base of the animal phylogenetic tree ...
This chain of sponge reefs is the largest known biostructure to have ever existed on Earth. [6] The sponge reefs declined throughout the Cretaceous period as coral and rudist reefs were becoming prominent. [6] It is theorized that the spread of diatoms may have been detrimental to the sponges, as diatoms compete with hexactinellid sponges for ...
A more probable set of stromatoporoid ancestors evolved in the Ordovician. These forerunners or close relatives are grouped in the incertae sedis sponge order Pulchrilaminida. Pulchrilaminids existed from the late Tremadocian stage (near the end of the Early Ordovician) up to the early Darriwilian stage (about mid-way through the Middle ...
