Where one can admire the Giant's Causeway? (a UNESCO World Heritage Site)
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. Most of the columns are hexagonal, although there are also some with four, five, seven or eight sides. It is one of the most popular tourist attractions in Northern Ireland.
By what means can hydrocarbons easily be detected in petrophysics?
Difference in Caliper size
RHOB and NPHI values being the same
Big difference in LLS, LLD and MFSL readings
Gamma ray readings seperating
Well logs measure different physical properties of the subsurface strata. Resistivity is measured very close to the tool (MFSL), at shallow depth from the tool (LLS) and at deep depths (LLD). If there is a big difference in the resistivities it means that the deeper formation contains hydrocarbons which have very high resistivity.
In which state of Australia would you find these rock formations?
New South Wales
The Three Sisters are an unusual rock formation in the Blue Mountains of New South Wales, Australia, on the north escarpment of the Jamison Valley. They are close to the town of Katoomba and are one of the Blue Mountains' best known sites.
In which country can you find the El Totumo mud volcano?
El Totumo Mud Volcano is an active mud volcano located near sea level in northern Colombia in the municipality of Santa Catalina. Situated beside a lagoon and 15m (49ft) high, it is a local tourist attraction.
How deep is the deepest borehole on Earth?
The Kola Superdeep Borehole is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970. The deepest, SG-3, reached 12,262 metres (40,230 ft; 7.619 mi) in 1989 and is the deepest artificial point on Earth, as of April 2019. The borehole is 23 centimetres (9 in) in diameter.
What is the highest active volcano in the world?
Ojos del Salado
Nevado Ojos del Salado is a stratovolcano in the Andes on the Argentina–Chile border and the highest active volcano in the world at 6,893 m (22,615 ft). It is also the second highest mountain in the Western Hemisphere and Southern Hemisphere and the highest in Chile.
Which rock monolith is the largest in the world?
Independence Rock, USA
Mount Augustus, Australia
La Peña de Bernal, Mexico
Mount Augustus is located in the Mount Augustus National Park in Western Australia. Mt Augustus is widely claimed in tourist promotional and information literature as the "world's largest monolith" but the claim does not originate from the geological literature, nor is substantiated by any other scholarly research. Mt. Augustus is more than twice the size of Uluru. Unlike Uluru, which is a monolith and, in general, devoid of plant growth, Mt. Augustus is a monocline.
What is the chemical symbol of silicon?
Silicon was identified as an element by the French physicist Antoine Lavoisier (1743-1794) in 1787. Stable silicon isotopes are 28Si, 29Si and 30Si. Silicon in nature occurs in the form of silicon dioxide and silicates, never in a free state. It plays an important role in the body - it is necessary along with vitamin C for proper collagen synthesis, conditions faster wound healing, improves the condition of hair, skin and nails, and removes aluminum from the body. It is also a good medium for actively growing tumors (eg leukemia and glioma), so it is forbidden to supplement it.
What is in the Egyptian Book of Caverns?
religious rituals and ceremonies
secrets of mummification of corpses
The Book of Caverns is an important Ancient Egyptian netherworld book of the New Kingdom. Like all other netherworld books, it is also attested on the inside of kings’ tombs for the benefit of the deceased. It describes the journey of the sun god Ra through the six caverns of the underworld, focusing on the interaction between the sun god and the inhabitants of the netherworld, including rewards for the righteous and punishments for the enemies of the worldly order, those who fail their judgment in the afterlife.
When was in Mexico the Paricutín volcano formed?
1 000 000 years B.C.
1 050 years B.C.
Parícutin is a cinder cone volcano located in the Mexican state of Michoacán, near the city of Uruapan and about 322 kilometers (200 mi) west of Mexico City. The volcano surged suddenly from the cornfield of local farmer Dionisio Pulido in 1943, attracting both popular and scientific attention.
