Because of the coastal mountains and greenhouse gases, California has a high-pressure environment that makes it hot. It stays hot for the majority of the year in California because of the state's high sunshine and low rainfall.
Why are Dallas, Atlanta, Charleston, and Southern California warmer in the winter than places at a same latitude?Most of the year, the Pacific Ocean on the West Coast is significantly colder than the Atlanta Ocean on the East Coast. Los Angeles, at 33N latitude, is warmer during the winter than Houston, at 29N latitude, despite the West Coast of North America lacking the Gulf Stream, which brings warm tropical water.
Mountains make a difference. Between the High Plains border in North Dakota and the Texas Gulf Coast, there are no mountains. The Arctic might bring frigid air to Texas. The frigid temperatures of the Blue Norther can kill even palm trees as far south as Texas and as far north as Florida. West of the Mississippi River, the Rocky Mountains obstruct some of these arctic Canadian air masses. As they travel further west, the tall Sierra Nevada Mountains further prevent California from being reached by freezing temperatures. Significant temperature shifts result from winter storms that are cold in the Gulf of Alaska warming up across the Pacific Ocean.
The "wet" season in Southern California, which lasts from late November to early April, is often irregular and is broken up by extended stretches of winter sunshine. Offshore winds have the potential to produce heat waves in the winter. The nation's warmest maximum temperatures have occasionally been recorded in California during these winter months. The hilly terrain creates microclimates where temperatures hardly ever frost and never drop below 40. The last time it touched freezing in Los Angeles and San Diego was years ago. It is therefore feasible to grow subtropical trees, fruit-nut trees, and flowers that are unique to South Florida or Hawaii.
However, it is typical for nightly lows to drop well below 50F and into the 30s throughout the winter in the interior. Even if one lives close to the beach, it's typical to switch on the furnace in the winter to stay warm. Frost is sporadic, but historically, subfreezing nights have been experienced in low-lying, wind-protected locations.

marlene zuk's work on field crickets of the hawaiian islands has shed much light on how natural selection can operate in the wild over short periods of time. which of the following phrases best describes zuk's primary findings?
Marlene Zuk and colleagues hypothesize that the Kauai population has evolved to be less choosy than other populations because of the high frequency of mute .
Do learning and natural selection operate independently?Natural selection can alter the frequency of various learning rules across generations, but learning can alter behaviour within a generation. Through learning, past events can change a person's behaviour over the course of their lifetime. Natural selection and learning are independent processes.
An individual's allele frequencies alter according to natural selection. -Natural selection affects an organism population's genetic diversity. - Traits that differ as a result of natural selection can either promote or decrease survival and reproduction.
There must be heritable variation in phenotypes and the variation in phenotype must be linked to differential survival and/or reproduction, or differential fitness, for natural selection to take place. The conclusion is that any organisms with heritable variation in reproduction rates are capable of evolving.

are thunderstorms low pressure systems
A tornado's core is characterized by low pressure, which is typically 10–20% lower than the atmospheric pressure around it.
Why are thunderstorms associated with low pressure systems?When air descends from a great height into a place, the pressure in that area rises, which causes the wind to blow outward. At the surface, there is a high pressure area.
A low pressure area is the opposite, when surface air is moving upward and drawing air inward along the surface.
Since the air is less dense at a height, little water can be held there. When that air is forced downward, it gets heated and compressed, which allows it to take in a lot more moisture. As a result, high pressure areas are usually clear and dry.
In contrast, the air close to the ground is warmer and denser (compared with high altitude air). The hot, humid air expands as it climbs, becoming less dense and cooling.

Choose the best answer. Which is an energy efficiency improvement? (4) adjusting the thermostat in a building (b) using a power strip (c) using cold water instead of hot water (d) replacing incandescent bulbs with LEDs
An energy efficiency improvement is replacing incandescent bulbs with LEDs.
Compared to LEDs, incandescent bulbs are less expensive. Despite LED's rising popularity over time, they are also more widely accessible. But LED is praised for having a long lifespan, being energy-efficient, and requiring less upkeep. Up to 50,000 to 100,000 operating hours, or around five to ten years, can be obtained from an LED light. As it wastes less energy by creating little heat, it is more energy-efficient than an incandescent. In addition, LED emits light in a specific direction rather than in a 360-degree circle as incandescent does; this conserves energy since it concentrates on a certain angle rather than requiring more energy for the entire 360 degrees. Despite being more expensive initially, LED also outperforms other lighting types in terms of maintenance expenses.
