What causes hot springs and geysers found in yellow stone?
Hot springs and geysers in Yellowstone are the result of the area's volcanic activity. Magma deep beneath the Earth's surface heats up groundwater, causing it to rise and create the hot springs and geysers. As the water reaches the surface, it releases steam and heat, resulting in the geothermal features found in Yellowstone National Park.
What is the earth's core consist of?
The Earth's core consists mainly of iron and nickel. It is divided into two parts: a solid inner core and a liquid outer core. The core is responsible for generating Earth's magnetic field.
Why did most scientists originally reject the theory of continental drift?
Most scientists originally reject the theory of continental drift since it did clearly explain continents would move. This is a theory that has been established by Wegener and did not get good support initially.
It seems there may have been a typo in the name you provided. If you mean Albert Wegner, he is known for being an investor and entrepreneur in the tech industry, particularly in the field of artificial intelligence and venture capital. He has invested in numerous successful startups and is a well-known figure in the tech startup community.
A seismic impulse is a sudden release of energy in the Earth's crust that causes vibrations to propagate as seismic waves. These impulses can be generated by various natural events like earthquakes, volcanic eruptions, or even human activities like mining or explosions. Scientists study these impulses to understand the structure of the Earth and to monitor potential hazards.
Where did the name Amber originate from?
Amber is fossilized tree resin, a thick material produced by a pine tree and oozed to help ward off bacteria, fill voids, and help heal injury from broken branches and other afflictions. The resin was eventually carried by water to deltaic deposits where it underwent chemical changes leading to its fossilization.
Who can be blame of having a typhoon?
No one person can be blamed for causing a typhoon as they are natural weather phenomena that result from complex interactions between the ocean and atmosphere. Typhoons can be influenced by climate change, greenhouse gas emissions, and other human activities, but they are ultimately a natural occurrence.
Auroras are produced when charged particles from the sun (solar wind) interact with the Earth's magnetic field and atmosphere. This interaction causes the particles to emit light, creating the colorful displays known as auroras.
What 2 features of a rock help us determine how the rock was formed?
Mineral composition and texture are two key features that can help determine how a rock was formed. The types of minerals present in a rock and how they are arranged provide clues about the conditions under which the rock formed, such as pressure and temperature. The texture of a rock (e.g. grain size, shape, and arrangement) can also indicate its formation process, like whether it cooled slowly deep within the Earth or quickly at the surface.
Rotation differences at time and location?
The point of the question is unclear.
I'll treat it as if it's asking for the speed of different points on earth, as the earth rotates daily.
The time doesn't matter. Only the location on earth.
The earth's diameter at the equator is 7,926 miles.
The circumference there is [ 7,926 pi ] = 24,900 miles.
The earth's rotation period is 23hrs 56min 4sec = 23.93444 hours.
The speed of a point on the equator is (7,926 pi) / (23.93444) = 1,040.35 miles per hour.
Anywhere else not on the equator, multiply that number by the cosine of the latitude.
Examples:
Latitude / Speed
zero degrees / 1,040.35 miles per hour
15 degrees / 1,004.9
30 degrees / 900.97
45 degrees / 735.6
60 degrees / 520.2
75 degrees / 269.3
90 degrees / zero
Give an exaple of a longitudinal and transverse wave?
An example of a longitudinal wave is sound waves, where the disturbance of particles is parallel to the direction of wave propagation. An example of a transverse wave is light waves, where the disturbance of particles is perpendicular to the direction of wave propagation.
Reaction about the movie the core?
Most fan reaction to the 2003 film "the Core" was not very favorable. It currently holds a 5.4 approval rating on IMDb and a 34% fan rating on the critical review site Rotten Tomatoes. Critical reaction was generally the same as the film only holds a 41% rating overall from critics.
When did Alfred wegener study plate tectonics?
Alfred Wegener studied plate tectonics during the early 20th century, particularly in the 1910s and 1920s. His theory of continental drift laid the foundation for the modern understanding of plate tectonics.
HAARP, High Frequency Active Auroral Research Program, does exist. It is a basic research project of the USA (other countries have similar facilities), and conducts fundamental research on the physical and electrical properties of the ionosphere.
The power that HAARP can apply to its transmissions is large. The largest legal AM radio antenna in North America is 50 kilowatts. HARRP operates in the HF (High Frequency) range and its power capability is about 72 times that, at approximately 3,600 kilowatts.
*From time to time the Alaska facility holds Open House events that anyone may attend.
Scouring action of particles carried by wind?
The scouring action of particles carried by wind, also known as abrasion, occurs when wind-blown particles impact and wear away surfaces by friction. This process can lead to the erosion of rocks, surfaces, or structures over time. Sand and other coarse particles carried by wind can act as abrasive agents, especially in arid and windy environments.
Did John Tuzo Williams contribute to Alfred Wegener's continental drift theory?
No, John Tuzo Wilson did not contribute to Alfred Wegener's continental drift theory. Williams was a geophysicist known for his research on plate tectonics, which built upon Wegener's ideas. He helped further develop the theory by proposing the concept of transform faults and the Wilson Cycle.
How do rock types and rock structure affect the rate of erosion?
Softer rock types like sandstone erode more quickly than harder types like granite. Additionally, rock structures like joints and fractures can create weak points that accelerate erosion through weathering processes such as freeze-thaw cycles and chemical dissolution. In general, resistant rock types and structures typically erode more slowly than those that are weaker or have more vulnerabilities.
What is the study of tides called?
The study of tides is called "tidal dynamics" or "marine hydrodynamics". It focuses on understanding the periodic rise and fall of sea levels caused by gravitational interactions between the Earth, Moon, and Sun.
what makes continents drift
the land used to be a big long peace of land. then we started having these big earthquake and natural storms and started breaking the earths crust and finally broke threw and made massive peaces of land drift away and the other land locked in and that's how the continents drifted called (continental drift)
What are the three principal solid spheres of the earth?
The three principal solid spheres of the Earth are the lithosphere (outermost layer made of the crust and upper mantle), the mantle (middle layer), and the core (innermost layer consisting of the outer and inner core).
A core virus is typically made up of a genome, which contains the virus's genetic material (DNA or RNA), surrounded by a protein coat called a capsid. Some viruses may also have an outer lipid envelope derived from the host cell membrane.
Where is the Weichert discontinuity?
The Gutenberg Discontinuity is the mantle/core boundary within Earth's interior where there is an abrupt change in the seismic waves (generated by earthquakes or explosions) that travel through Earth. It is at a depth of about 1,800 mi (2,900 km) below the surface.
