Please answer correctly the following question related to the paragraph below.   Would mountain summit A need higher temperature or lower temperature to boil water compared to mountain summit B?  Ken is an avid mountain climber. This year he reached the summits of two mountains, mountain A and mountain B. Mountain A is only 5000 ft tall while mountain B is  15000 ft tall. He has also learned a fun fact that water boils faster and at lower temperature at low atmospheric pressure.  Hint: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7]  At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]

Answer: higher temperature


Please answer correctly the following question related to the paragraph below.   Which friend studied less about seismic waves going different speeds through different materials?  Two friends met after 20 years and had a beer together. Vlad was a geologist and studied earthquakes. Mort was a pedologist and studied soils. They had some interesting conversations that night.  Hint: Geologists study earthquake waves to “see” Earth's interior. Waves of energy radiate out from an earthquake’s focus. These waves are called seismic waves ( Figure below ). Seismic waves go different speeds through different materials. They change speed when they go from one type of material to another. This causes them to bend. Some seismic waves do not travel through liquids or gases. They just stop. Scientists use information from seismic waves to understand what makes up the Earth’s interior.

Please answer correctly the following question related to the paragraph below.   Would location B have lower or higher salinity than location A?  John sailed across two oceans last year. First, he sailed across the Atlantic Ocean, which he noted as location A. Then he sailed across the Arctic Ocean, which he noted as location B. He was so amazed by the Arctic Ocean that he sailed across that ocean twice, time C and time D. Time C was in the summer,and time D was in the winter.  Hint: Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere, the Arctic Ocean is almost completely surrounded by Eurasia and North America. It is partly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years.
