the geologic time scale was created by one scientist, nicholas steno. True or False
The statement 'the geologic time scale was created by one scientist, Nicholas Steno' is false as other scientists were also involved in the creation of the geologic time scale.
Nicholas Steno is often credited with creating the geologic time scale, but this is not the case.
In fact, the geologic time scale was the result of contributions from numerous scientists over several centuries.
Steno's key contributions include the principles of superposition, which states that older rocks are found below younger rocks, and the principle of original horizontality, which states that sedimentary rock layers were originally deposited in a horizontal position.
While these contributions were important to the development of the geologic time scale, they were only part of a much larger picture.

which boundary is associated with the building of the himalaya mountains?
Mountain ranges are produced when two continental plates collide. This kind of convergent plate boundary produced the magnificent Himalaya Mountains.
When two continental plates meet, it forms a convergent plate boundary. The continental lithosphere is quite thick and has a low density. The lithosphere of a continent cannot subduct. Therefore, when two continental plates meet, they simply crash into one another. Similar to what happens when you place your hands on opposite sides of a piece of paper and pull them together, this also occurs. The only direction the material can go is up (see figure below)! Earthquakes and metamorphic rocks are produced as a result of the collision's extremely strong forces. But magma cannot penetrate the crust because it is too thick. Therefore, there are no volcanoes in the areas where two continents collide.

famous archaeological site in jordan crossword clue
The well-known archaeological site Petra is located in the desert in southwest Jordan.
In the southwest of Jordan, in the Wadi Mousa, or Valley of Moses, are the beautiful remains of ancient Petra. Petra, the former seat of the Edomite Kingdom, was taken by Nabataean invaders in 300 BC, solidifying their control of the area. It served as the Nabatean Kingdom's capital. It is referred known as the "Rose City" because of the tombs and temples that are carved into the pink sandstone cliffs that may be reached via a small canyon called Al Siq. The 45-meter-tall Al Khazneh, also known as The Treasury and with an elaborate Greek-style exterior, is arguably the most well-known building there.

led expedition to sail around the world, but died in the philippines. is first mate elcano completes the journey with a few remaining men.
Ferdinand Magellan was a Portuguese explorer who led the first expedition to sail around the world. He set out with five ships and a crew of about 270 men in 1519. The expedition was sponsored by King Charles I of Spain, also known as Charles V of the Holy Roman Empire, who wanted to find a new route to the Spice Islands of the East Indies and establish a Spanish presence in the region.
He had to navigate treacherous waters and unknown lands and had overcome the resistance of his crew, who were often reluctant to continue the journey. Despite these challenges, Magellan pressed on, and in 1520, he became the first European to cross the Pacific Ocean.
However, despite his successes, Magellan's journey ended tragically. In April 1521, he and his men landed in the Philippines, where they were involved in a battle with the local tribes.
Magellan was killed in the battle, and his crew was left without a leader. But, his first mate, Juan Sebastián Elcano, who was appointed as leader of the expedition, decided to complete the journey. With a few remaining men, Elcano set sail and continued the voyage.
In September 1522, Elcano and 18 men returned to Spain, after completing a three-year voyage. They were the first expedition to circumnavigate the world, proving that the earth was round and opening a new era of maritime exploration and trade.
The expedition also established a Spanish presence in the East Indies and opened the way for further exploration and colonization of the region.

Geologists attempt to understand the history of Earth by studying rocks. (T/F)
True. Geologists use rock formations to gain insight into the different forces that shape the Earth, such as volcanic eruptions, earthquakes, and meteorite impacts.
By studying the composition of the rocks and their placement on the Earth's surface, geologists can discern the Earth's past and gain a better understanding of its geological history. Geologists are scientists who study the Earth and its components, processes, and history. They use a variety of tools and techniques to understand the Earth's physical, chemical, and biological structure and processes. Geologists typically have a bachelor's degree in geology or a related field and may specialize in a particular area such as environmental or engineering geology. Fieldwork is an important part of a geologist's job and they may be involved in surveying land, collecting samples, and analyzing data. They may also be involved in the development of natural resources, the prevention of natural hazards, and climate change research. William Maclure produced the first geological map of the United States in 1809 and Charles Lyell published his famous book Principles of Geology in 1830, promoting the doctrine of uniformitarianism. Geologists may also have skills in GIS and mapping techniques and field experiences are common parts of a geologist's education. Geologists may be found in a variety of industries, including mining, environmental assessments, land development, and land remediation.

Which part of the electromagnetic spectrum can humans sense without using equipment or technology?
a. radio waves
b. visible light
c. microwaves
d. X-rays
Humans are only sensitive to a relatively limited portion of the electromagnetic spectrum that is associated with light. It is visible light.
The area of the electromagnetic spectrum that is visible to human eyes is known as the visible light spectrum. Simply put, this group of wavelengths is referred to as visible light. Usually, the human eye is capable of detecting wavelengths between 380 and 700 nanometers.
Only a small amount of electromagnetic radiation, which we refer to as visible light, can we perceive, whereas all electromagnetic energy is light. Our eyes' cone-shaped cells function as wavelength-tuned receivers for electromagnetic waves in this specific band. For the biological restrictions on our perception, other parts of the spectrum have wavelengths that are either too big or too small and energetic. The colors of the rainbow are separated into their individual wavelengths as visible light travels through a prism. While violet has a wavelength of roughly 380 nanometers, red is about 700 nanometers.

german scientist that developed theory of continental drift
The theory of continental drift, which holds that Earth's continents move, was put forth by German scientist Alfred Wegener.
The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. He referred to it as continental drift.
Between 1912 and 1929, he published a substantial amount of convincing fossil and geological evidence in support of his theory, but most other scientists disregarded it. The concept of continental drift didn't enter the mainstream of science until the 1960s.

where did the water that makes up our oceans come from?
When the Earth's surface cooled below the boiling point of water, rain began to fall and lasted for centuries. The primordial ocean formed as water drained into large voids on Earth's surface.
Due to the effects of gravity, the water was unable to leave the planet.
The majority of scientists agree that the ocean and atmosphere grew gradually over millions of years due to the continuous "degassing" of the Earth's interior.
According to this theory, the ocean formed as a result of water vapor and other gases escaping from the Earth's molten rocks and entering the planet's atmosphere as it cooled.
