Are Sticky thicker lavas rich in silica?
Yes, sticky thicker lavas are rich in silica. This high silica content makes them more viscous and less likely to flow easily, leading to more explosive volcanic eruptions. Examples of these lavas include dacite and rhyolite.
Is the composition of the hawaiian lavas felsic or mafic?
The composition of Hawaiian lavas is typically mafic, as they are rich in magnesium and iron and have a lower silica content. This composition gives them low viscosity and allows them to flow easily.
What is Ol Doinyo Lengai?
Ol Doinyo Lengai is an active volcano located in Tanzania. It is known for its unique lava composition that is rich in sodium carbonate minerals, giving it a dark color and making it cooler in temperature compared to other lavas. The Maasai people consider it a sacred mountain.
What is the effect of aphids on plants?
Edible, herbaceous, ornamental, wild, and woody are the plants which aphids attack. The insects in question (Aphidoidea superfamily) -- which may be indiscriminate or species-specific -- feed upon whatever plants can supply them bacterial sources of essential amino acids as well as phloem (down-flowing, enriched liquids flowing down from foliage) and xylem (intake liquids flowing up from roots) sap.
Which layer of the earth is composed of rocks rich with silicon and aluminum?
The layer of the Earth composed of rocks rich in silicon and aluminum is the crust. The crust is the outermost layer of the Earth, and it includes both the continental crust, which is thicker and primarily made up of granitic rocks, and the oceanic crust, which is thinner and predominantly composed of basaltic rocks. These rocks are characterized by their higher concentrations of silicon and aluminum compared to other layers of the Earth.

What kind of lava does composite volcanoes produce AA or pahoehoe?
Usually neither. A'a and pahoehoe lavas are both of mafic composition (rich in iron and magnesium, poor in silica) and form basalt when they cool. Composite volcanoes usually erupt material of intermediate to felsic composition (felsic is rich in alkalis, aluminum, and silica), with lavas cooling into rocks such as andesite, dacite, and rhyolite.
