What breeze blows in a mountain-valley system?
During the day, warm air rises up the mountain slopes, creating anabatic winds blowing up the valley. At night, cold air descends down the slopes, creating katabatic winds blowing down the valley. This diurnal pattern of wind movement is typical in mountain-valley systems.
Did Mount St Helens produce major environmental damage?
Yes, the eruption of Mount St. Helens in 1980 caused major environmental damage, including the destruction of forests, rivers, and wildlife habitats. It also led to the loss of plant and animal species, as well as significant changes to the landscape that took years to recover from.
What are some animals and plants that live in mount Whitney?
Bears, marmots, mice, squirrels, quail, robins, deer, and blue jays live on Mount Whitney. Campers should take precautions regarding bears and marmots. Marmots will chew through a tent to get to any food they can smell. Food and empty food containers must be stored in bear-proof boxes.
What buried the town of Pompeii?
The eruption of Mount Vesuvius in 79 AD buried the town of Pompeii under a thick layer of volcanic ash and pumice. This preserved the town and its inhabitants for centuries, providing valuable insights into Roman life and culture.
Why might your inner ears 'pop' when you are driving through the mountains?
Your inner ears 'pop' while driving through the mountains due to changes in altitude. As you ascend or descend, the air pressure around you changes, causing your Eustachian tube to equalize the pressure in your middle ear, resulting in the popping sensation you might feel.
What plates are causing Mount Rainier to form?
Mount Rainier is formed due to the Juan de Fuca tectonic plate sliding beneath the North American plate in a process called subduction. This subduction leads to the melting of the Earth's mantle, creating magma that eventually rises to the surface and forms the volcano.
What are the two mountains with snow in Africa?
The two mountains in Africa with snow are Mount Kilimanjaro in Tanzania and the Rwenzori Mountains (also known as the Mountains of the Moon) on the border of Uganda and the Democratic Republic of the Congo.
What weather process produces snow in the Rocky Mountains?
Snow in the Rocky Mountains is typically produced by a process called orographic lifting. As moist air is forced upward by the mountain range, it cools and condenses, leading to the formation of snow. This process results in higher snowfall amounts on the windward side of the mountains.
What happens to the radii of the elements between 2 highest peaks?
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
What happens to the temperature if you climb up a mountain?
The temperature generally decreases as you climb higher up a mountain due to lower air pressure and thinner atmosphere. This change in temperature with altitude is known as the lapse rate, and it results in colder temperatures at higher elevations.
What city is closest to the Sierra Nevada?
The city of Reno in Nevada is closest to the Sierra Nevada mountain range.
How did mount st Helens become a volcano?
Mount St. Helens was created by the interactions of the North American plate and the Juan de Fuca plate. The Juan de Fuca plate is an oceanic plate, made of material which is denser than continental plates, such as the North American plate. The Juan de Fuca plate and the North American plate are currently moving towards each other, and Juan de Fuca plate is going underneath the North American plate because it is denser. This allows for magma to come to the surface, and it creates a volcano.
What is the chief mountain range of North America?
The chief mountain range of North America is the Rocky Mountains. This mountain range extends more than 3,000 miles from Canada to New Mexico and contains several major peaks over 14,000 feet in elevation.
Fault block mountains are primarly the result of faulting and?
uplifting of large blocks of the Earth's crust due to tectonic forces. This process causes one block to move upward while the adjacent block moves downward, creating a series of steep mountain ranges and valleys. Over time, erosion can further shape these fault block mountains into their distinct jagged peaks and ridges.
What are Mount St Helens emergency procedures?
In the event of an emergency at Mount St. Helens, authorities may issue evacuation orders, warnings, or closure of access roads. Visitors are advised to follow instructions from park rangers, monitor local news and weather reports, and be prepared to evacuate quickly if necessary. It is important to have an emergency kit with essentials such as food, water, first aid supplies, and a communication device.
Scientist have found fossils on the tops of mountain?
The discovery of fossils on mountain tops supports the theory of plate tectonics, as it indicates that these areas were once at lower elevations where fossils could form. Over time, the movement of tectonic plates pushed these areas upwards to form mountains, carrying the fossils with them. This provides evidence of the dynamic nature of the Earth's crust and the processes that shape the planet's surface.
What are Cambodia's major landforms?
The nation has three major mountain ranges,
-The Cardamom Mts.
-Dangret Mts.
-Eastern Highlands.
The major river is the Mekong, which naturally forms the Tonle Sap, an important farming area for Cambodia.
What type of mountain is mt lhotse?
Certainly Mount Lhotse leans a bit towards Tibet, but I believe it's more in Nepal. Either way ist's a tremendous mountain soaring 27,890 feet. It's ranked as the fourth highest mountain in the world.
When was Mount Shasta's last eruption?
Mount Shasta's last known eruption occurred around 1786. Since then, there have been no recorded eruptions, and the volcano is currently considered to be dormant.
Why life more difficult in Western mountains as compared to northern mountains?
Life can be more difficult in Western mountains compared to northern mountains due to factors such as harsher weather conditions, rugged terrain which can limit access to resources, and limited infrastructure. Western mountains, like the Rockies, can have more extreme weather patterns and higher elevations, making it challenging for people to live and work in these environments.
Is air density greater at the top or the bottom of a mountain?
Air density is greater at the bottom of a mountain due to the higher atmospheric pressure caused by the weight of the air above. As you move higher up the mountain, the air becomes less dense because the pressure decreases with altitude.
Mountains are jagged because the moon has no what?
Because just like the earth, the moon has been bombarded by meteors for billions of years. The reason you see very few craters on earth is because the walls of earthly craters erode inward leaving a nice shallow depression that is barely noticeable from the surface. The lack of atmosphere on the moon leaves craters virtually untouched other than by other impacts. Erosion occurs on the moon from several sources; solar wind, and spray from the creation of new craters. There is also a very small amount of erosion due to expansion and contraction as a result of the extreme temperature differences between the lunar night and day.
What is a mountain that is a fault-block mountain?
These mountains form when faults or cracks in the earth's crust force some materials or blocks of rock up and others down.
Instead of the earth folding over, the earth's crust fractures (pulls apart). It breaks up into blocks or chunks. Sometimes these blocks of rock move up and down, as they move apart and blocks of rock end up being stacked on one another.
Why is the boiling point of water lower in the mountains than it is in the sea?
The boiling point of water is lower in the mountains due to the decrease in atmospheric pressure at higher altitudes. The lower pressure makes it easier for water molecules to escape into vapor form, resulting in a lower boiling point. In contrast, the higher pressure at sea level keeps water molecules more tightly bound, requiring a higher temperature to reach the boiling point.
How can mountain ranges limit a species distribution?
Mountain ranges can limit a species' distribution by creating physical barriers that prevent species from moving between different habitats. The steep, rugged terrain and varying climate conditions can create barriers to dispersal and limit access to resources like food and shelter. As a result, species on one side of a mountain may have limited gene flow with populations on the other side, leading to genetic isolation and potential divergence.
