Answer:
The Pacific Crest Trail (PCT) is approximately 2,650 miles (4,265 kilometers) long, stretching from the U.S.-Mexico border in California to the U.S.-Canada border in Washington. The time it takes to hike the entire trail varies depending on factors such as hiking speed, daily mileage, and weather conditions.
On average, it takes most thru-hikers about 4 to 6 months to complete the entire Pacific Crest Trail. Some experienced and well-prepared hikers may finish the trail in a shorter time, while others may take longer, especially if they choose to take more rest days or explore nearby attractions along the way.
Use the sketch to differentiate between surface runoff and throughflow
In contrast to throughflow, which seeps through the soil and is stored in the soil and groundwater, surface runoff is the water that pours over the top of the land.
The water flow that happens on the surface of the land is known as surface runoff, and it typically follows a very severe downpour or snowmelt. Since it travels swiftly down hillsides and into streams, rivers, and lakes, this type of water flow is simple to see.
Water that slowly percolates through the soil and underlying rocks on its route to a stream or river is known as throughflow. Although this type of water flow is harder to see, it is nonetheless a crucial component of the hydrologic cycle.

what change in arctic seas caused the global ocean conveyor belt to stop abruptly in the past? group of answer choices decreased salinity decreased temperature increased salinity increased temperature
A decrease in salinity caused the global ocean conveyor belt to stop abruptly in the past.
Melting ice from glaciers and increased freshwater input from rivers diluted the salinity of the Arctic seas, which affected the formation of dense, salty water that drives the conveyor belt. This disruption to the conveyor belt system had significant effects on global climate patterns, including cooling in the North Atlantic region.
The global ocean conveyor belt, also known as the thermohaline circulation, is driven by differences in temperature and salinity. In the past, a significant decrease in salinity in the Arctic seas, possibly due to the influx of freshwater from melting ice, disrupted the density-driven circulation. This caused the conveyor belt to stop abruptly, leading to changes in global climate patterns.

coral is a hard, rock-like substance which is made by small sea animals called coral polyps. rings of coral, called atolls, sometime form around sunken volcanoes.
This statement contains some inaccuracies. While coral is indeed a hard, rock-like substance made by small sea animals called coral polyps, atolls do not form around sunken volcanoes.
Rather, atolls are formed by the buildup of coral reefs over thousands of years on the rim of submerged volcanic mountains or seamounts, which eventually erode and sink beneath the ocean surface. The coral polyps then continue to build their reefs upwards towards the surface, creating a ring-shaped coral formation with a lagoon in the center. Atolls are found primarily in tropical regions and are home to a diverse array of marine life.

Approximately how often do locked segments of the san andreas fault (california) break, resulting in major earthquakes? once every ten thousand years once every fifteen years once every hundred and fifty years once every six hundred years
The frequency of major earthquakes caused by locked segments of the San Andreas Fault is approximately once every 150 years.
The San Andreas Fault is a transform boundary that separates the Pacific Plate from the North American Plate, and it is one of the most studied faults in the world due to its high seismic activity. The locked segments of the fault are areas where the tectonic plates are stuck together, and when they eventually break, they release large amounts of energy in the form of earthquakes.
The last major earthquake caused by a locked segment of the fault occurred in 1857, which means that California is overdue for another major earthquake. Scientists continue to study the San Andreas Fault to better understand its behavior and potential for future earthquakes in order to better prepare and mitigate the impact of seismic activity on communities in the region.

6. if you live near a large body of water, in the winter it is often slightly warmer close to the water than it is further inland. explain why this is the case based on the principles of thermochemistry.
Large bodies of water have a higher heat capacity than land, meaning they can absorb and retain more heat energy. In the winter, the water temperature takes longer to cool down than the surrounding land temperature. As a result, the air temperature close to the water is slightly warmer than the air temperature further inland.
The principles of thermochemistry, which explain the transfer of heat energy. Heat energy always flows from an object with a higher temperature to one with a lower temperature. In the case of a large body of water and surrounding land, the water has a higher heat capacity and can absorb and retain more heat energy than the land.
During the day, the sun's energy heats both the water and the land, but the water takes longer to cool down than the land as it has a larger thermal mass. At night, the water gradually releases its stored heat energy, which warms the surrounding air. This phenomenon is known as the "lake effect," and it results in slightly warmer temperatures close to the water than further inland in the winter.
In summary, the higher heat capacity of large bodies of water allows them to absorb and retain more heat energy than land, resulting in slightly warmer temperatures close to the water than further inland in the winter.

Charles Lyell's idea that influenced Darwin's thinking was the concept of uniformitarianism, which stated that the geological processes that shaped the Earth in the past are the same processes that are still shaping it today.
This idea challenged the prevailing view of catastrophism, which held that the Earth's history was shaped by sudden and catastrophic events. By showing that the Earth's features were the result of gradual, ongoing processes, Lyell provided a framework for understanding the slow and incremental changes that drive evolution. Lyell's ideas helped Darwin to see that the distribution of plants and animals across the globe was not due to sudden acts of creation, but rather the result of long-term geological processes.
Charles Lyell, a geologist, and friend of Charles Darwin, influenced Darwin's thinking with the idea that Earth's geological processes occur gradually over long periods of time, also known as uniformitarianism. This concept suggested that the Earth was much older than previously thought, allowing sufficient time for the gradual evolution of species. Lyell's ideas supported Darwin's theory of natural selection, as they provided an extended timeframe for the development of the diverse species found on every continent. By considering the evidence from geology, both Lyell and Darwin were able to revolutionize our understanding of the natural world.

Seasons are brought about by both the Earth's axis and rotation around the sun. Without the tilt of the earth's axis to its orbital plane, seasons would not have been conceivable and humanity would have suffered.
The Earth's axis tilt causes the seasons. At various times of the year, the Sun's rays reach various parts of the Earth. The North Pole's tilt towards the Sun causes the Northern Hemisphere to have summer. The Northern Hemisphere also experiences winter during the South Pole's tilt towards the Sun.
If the Earth didn't rotate on its axis, one side would always be facing the Sun and the other would be facing away from it. One side would thus become incredibly hot, while the other side would become extremely cold. The eventual result would have been that life would not have been imaginable.
