Ques:Answer the following question given this paragraph: Composite volcanoes are also called stratovolcanoes. This is because they are formed by alternating layers (strata) of magma and ash ( Figure below ). The magma that creates composite volcanoes tends to be thick. The steep sides form because the lava cannot flow too far from the vent. The thick magma may also create explosive eruptions. Ash and pyroclasts erupt into the air. Much of this material falls back down near the vent. This creates the steep sides of stratovolcanoes. The composition of magma that erupts at composite volcanoes is usually felsic (rhyolite) or intermediate (andesite). Q: What is another name for composite volcanos? Choices: - fjords - fault lines - seismic giants - stratovolcanoes A:

Ans:stratovolcanoes

Ques:Answer the following question given this paragraph: Acetylene is an interesting example of a molecule with two central atoms, which are both C atoms. Polyatomic ions are bonded together with covalent bonds. Because they are ions, however, they participate in ionic bonding with other ions. So both major types of bonding can occur at the same time. Q: What is an interesting example of a molecule with two central atoms, which are both c atoms? Choices: - chloride - water - sulfur - acetylene A:

Ans:
