Question

1. In general, why is it really wet in Eureka, CA and quite dry in San Diego, CA?

2. How would you measure net primary production in a bean plant?

3. Is the length of daylight in Bakersfield today different from that at the North Pole? Explain

Answer 1

1. California's climate varies widely from hot desert to polar,dependig on latitude, elevation, and proximity to the coast

Eureka, california gets 46 inches of rain, on average, per year. In Eureka, the summer are cool, dry, ad mostly clear and the winters are long, cold,wet,windy, and mostly cloudy. over the course of the year, the temperature typically varies from 42 degree farenheit to 64 degree farenheit and is rarely below 33 degree farenheit or above 71 degree farenheit. A wet day is one with atleast 0.04 inches of liquid or liquid-equivalent precipitation.The chance of wet days in eureka varies significantly throughout the year. Among wet days,we distinguish between those that experience rain alone,snow alone,or a mixture of the two.Based on this categorization, the most common form of precipitation throughout the year is rain alone,with a peak probability of 46%.

As the air flows equatorward, it enhances its negative vorticity ( sinking motion from the upper-level anticyclone and monsoonal trough), and this further dries out southern california, reaching an equilibrium only when surface friction slows the drying. The climate of san diego, california is classified as a mediterranean climate. the basic climate features hot,sunny,and dry summers,and cooler, wetter winters.however, san diego is much more arid than typical mediterranean climates, and winters are still dry compared with most other zones with this type of climate.

2. In ecology, primary production is the synthesis of organic compounds from atmospheric orr aqueous carbon dioxide. it principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. almost all life on earth relies directly or indirectly on primary production. the organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. in terrestrial ecoregions, these are mainly plants , while in aquatic ecoregions algae predominate in this role.ecologists distinguish primary production as either net or gross , the former accounting for losses to processes such as cellular respiration, the latter not.

3.The length of daylight in bakersfield today is 12h 30m. the length of a solar day is determined by the time that it takes for the earth to complete a full rotation around its axis and equals 24 hours. the earth's rotation on its axis leads to change between day and night. another consequence of this rotation is the fact that while moving by 15 degree from west to east local solar time increases by an hour.

The north pole receives 163 days of total darkness and 187 days of midnight sun each year.by contrast, locales on the artic circle recieve just 30 days of midnight sun.According to the definition of " day " above, midnight comes only comes once a year at the north and south poles. some three months after the december solstice, around the march equinox, the sun will finally set at the south pole and rise at the north pole.
