Why does more evaporation happen from the oceans than from freshwater sources?
Why does more evaporation happen from the oceans than from fresh-water sources? Oceans have a greater surface area. Salt water evaporates faster than freshwater. The air over oceans can hold more water vapor.
Which factor increases the potential of a low pressure system developing into a hurricane in the northern hemisphere?
When air rises over the open ocean, a low-pressure system is formed. Which factor increases the potential of a low-pressure system developing into a hurricane in the Northern Hemisphere? The blue water from the jar rises to the top of the bowl.
Which best describes the temperature change that occurs as elevation increases within the troposphere?
Temperature decreases as you gain altitude in the troposphere and mesosphere.
Which best explains why air temperatures near mountaintops are often much colder than air temperatures near sea level *?
As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.
What causes water to evaporate in the ocean?
During the day, the sun heats up the air and ocean surface, causing water molecules to evaporate. Evaporation occurs when a liquid molecule of water escapes into the air as a gas. … Over the ocean, evaporation appears to remain constant, both day and night. Water in the air in gas form is known as water vapor.
Why is the water vapor fresh water when it rises from the ocean?
The water vapor is freshwater when it rises from the ocean because during evaporation, it leaves the ocean’s salt and other particles behind. … Freshwater in the form of snow takes longer to enter the water cycle again than liquid precipitation because it has to melt first.
What is the most likely cause of high and low pressure systems?
The Earth’s atmosphere exerts pressure on the surface. … Areas of high and low pressure are caused by ascending and descending air. As air warms it ascends, leading to low pressure at the surface. As air cools it descends, leading to high pressure at the surface.
Which if the following best explains why the lower portion of the troposphere is warmer than the upper portion?
Which of the following best explains why the lower portion of the troposphere is warmer than the upper portion? The surface of Earth absorbs sunlight, heating the lower portion of the troposphere more than the upper part. … The Sun warms the moist air at the equator and causes it to rise because of its lower density.
What factor will increase the chances of a low pressure system developing into a hurricane?
Warm sea surface temperatures–This is a key ingredient because it serves as the fuel source for hurricanes. Sea surface, or ocean temperatures need to be at least 80 degrees Fahrenheit (27 degrees Celsius) where the system is located in order for it to develop into a tropical storm or hurricane.
Which statement best explains why temperature rises with altitude in the stratosphere?
Temperature in the stratosphere rises with increasing altitude, because the ozone layer absorbs the greater part of the solar ultraviolet radiation. The ozone layer is an absorbing agent that protects life on Earth.
Why does temperature decrease as altitude increases?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands), and the temperature decreases.
Which of these statements best describes explains temperature as elevation in the atmosphere increases?
Which of these statements best describes temperature as elevation in the atmosphere increases? Temperature remains constant with elevation in the mesosphere.
