In 2004, an earthquake struck Sumatra in Indonesia along a tectonic plate boundary under the ocean. When the plates shifted, it caused a tsunami wave to spread outwards and hit different coastlines anywhere from 2 to 8 hours after the quake. Unfortunately, the tsunami waves were so powerful that it became known as one of the deadliest natural disasters in history with over 220,000 deaths and $14 Billion in damages. Which of the following is the NOT a likely reason why the 2004 Sumatra earthquake caused so much damage?

A. Tsunamis occur instantly and are not preceded by any warning signs.

B. Poor earthquake detection systems did not give people warnings to move farther inland.

C. Most of the countries affected by the tsunami were poor and did not have well-established building codes.

D. The earthquake that caused the tsunami was a magnitude 9.2.

During metamorphic processes, increased pressure and temperature can affect the of minerals in rock. rocks subjected to very high pressure are typically than others because mineral grains are squeezed together, and the atoms are more closely packed. during metamorphic processes, water facilitates the transfer of ions between and within minerals, which can the rate at which metamorphic reactions take place. the growth of new minerals within a rock during metamorphism has been estimated to be about per million years. metamorphism is commonly associated with convergent plate boundaries, where two plates move toward each other. during contact metamorphism, a large intrusion will contain thermal energy and will cool much more slowly than a small one. metamorphosed sandstone is known as the metamorphic rock made from metamorphosed shale, was once used to make blackboards for classrooms.

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
