Answer and Explanation:
About two-thirds of the Earth's surface lies beneath the oceans. The depths of the open ocean were mostly a matter of speculation before the 19th century. Most people thought ocean floor was flat and featureless. In the early 16th century, a few navigators found that the open ocean can differ considerably in depth by taking soundings with hand lines, which shows that the ocean floor was not as flat as it believed.
At the beginning of the 1950s, scientists used magnetic instruments adapted from airborne devices to recognize odd magnetic variations across the ocean developed during World War II to detect submarines. They found that the iron-rich and volcanic rock make up the ocean floor-- contains a strongly magnetic mineral and can distort compass readings. In the early 18th century, this distortion was recognized by Icelandic mariners. Magnetite gives measurable magnetic properties; these magnetic variations help to study the deep ocean floor.
Does Iceland have a railway system???
Answer:
Iceland does not have a public railway system. There have been three small railways, but none became part of the public transport network. The main reasons for the lack of railways are the small population, competition with automobile traffic, and the harsh environment.
Answer:
Trains have been used in the past but Iceland is too small and people have started using cars for travel.

It is common to hear that "the higher you go, the cooler it becomes"This is scientifically correct. The reason for this is that the atmosphere is made up of gases. The earth is a better heat conductor. It absorbs more heat and the gases close to the ground will have more heat energy. The gases farther from the earth surface will be cooler than those in contact with the ground.List ten things to boost yourself esteem or improve yourself concept . Support your idea and examples.

Water Consumption All living organisms on Earth need water to survive. Many, including humans, require fresh water, but only 3% of the water on the Earth's surface is fresh water. How is fresh water important to you? How does this affect the way you manage your use of fresh water? Write an essay that explains how you use and conserve fresh water based on how important it is to you. Support your explanation using evidence, such as facts and examples. As you write, remember your essay will be scored based on how well you: develop a multi-paragraph response to the assigned topic that clearly communicates your controlling idea to the audience. support your controlling idea with meaningful examples, information, and references from the text. cite direct quotes and any information that has been paraphrased from the passages that you have read. organize your essay in a clear and logical manner, including an introduction, body, and conclusion. use well-structured sentences and language that are appropriate for your audience. edit your work to conform to the conventions of standard American English. Use any of the tools available to you, such as the Checklist, Spellchecker, or Graphic Organizer.
Explanation:
Water is probably the most important substance for preserving life. In fact, scientists looking for evidence of life on other planets regard the presence of water as a vital clue. In developed nations we tend to take water for granted because it flows easily out of the tap. But we are rapidly depleting the global supply of fresh water, and this reality could potentially have dire consequences.
Our bodies need water to function properly. According to Water.org, humans can survive for weeks without food, but for only a few days without water. The plants and animals we eat require water as well, so water crises inevitably become food crises. We also use water for cleaning our bodies and our homes, and for producing power such as in hydroelectric dams. The World Water Council reports that the human population of the planet is on track to grow 40 to 50 percent within the next 50 years, putting additional pressure on our already shrinking supply of fresh water.
Vegetables, Meat and Water
Plants require water to grow. A growing human population consumes an increasing amount of food, which requires additional water. The animals that we eat consume water, and they also eat grains and grass that require water. Raising meat uses considerably more water than raising plant foods. As populations in different parts of the world become more affluent, they eat more meat and fewer plant-based foods. This shift places an added strain on the already short supply of fresh water.
Water and Global Warming
A hotter planet means an increased demand for water. Heat causes water to evaporate more quickly. Even if higher temperatures do not necessarily correlate with decreased rainfall, more of the water that does fall evaporates into the atmosphere rather than providing sustenance for crops. Hotter temperatures also diminish the amount of water available in lakes and rivers. Conserving water enables us to use our existing supply of water more efficiently.

To change it to a solid
Answer:
The earth is made out of layers that separate according to their densities.
The density of each layer is affected by the composition of the material and the amount of pressure it is under.
The thinnest and least dense layer is known as the Crust.
The layer under the most pressure is known as the core.
Such high amounts of pressure cause this layer to remain in a Solid State of matter even though the nickel and iron are at such a high temperature.
On the other hand, the outer core remains in a molten state of matter even though it is made out of the same materials as the inner core since there is not enough pressure to change it to a solid.
Explanation:
The above question now updated with the missing words provide information about how the compositional layers of the earth's crust are formed.
The three major determinants as already explained about how the layers have come to be are:

The Mantle is a combination of silica, magnesium, and iron.
The core is a combination of oxygen, nickel iron and sulphur.

How long could Bay Area residents be without drinking water due to an earthquake on a strike-slip fault of the San Andreas?
a. Up to one month
b. Up to 2 months
c. Up to seven months
d. Up to nine months
e. Up to three months
f. Up to 5 months
Up to one month long could Bay Area residents be without drinking water due to an earthquake on a strike-slip fault of the San Andreas. Hence, option A is correct.
What type of strike-slip is the San Andreas Fault?The San Andreas Fault is a strike-slip fault that rose to fame during the San Francisco earthquake of 1906. This shows that two fault blocks are moving past one another horizontally. In situations when two plates are slipping past one another, strike-slip faults commonly form.
On a strike-slip fault, the two blocks pass one another. The San Andreas Fault is an example of a right lateral fault.
39 gas and oil pipelines intersect the San Andreas Fault in various locations, according to the narrator. Damage to high-pressure gas pipes could result in gas leaks into the atmosphere and potentially lethal explosions. Stewart: As a result, damaged natural gas pipes can cause fires and explosions.
Thus, option A is correct.

Using the known rates of radioactive decay to date the crystallization of certain minerals is known as ________ dating.
a. Conventional
b. Radiometric
c. Relative
d. Fossil assemblage
Answer:
The correct answer is: b. Radiometric.
Explanation:
Radiometric dating, or radioactive dating, is a method that is utilized to learn the age of materials such as rocks by comparing the known affluence of a naturally occurring radioactive isotope with its decay products, which are formed at known constant rates. This means that they understand how old a material is by looking at how fast its radioactive components decay.
Radiometric dating is used by setting geological timescales and thus, it supplies with a great amount of information about the date of fossils, among other things.
What other factors might contribute to a species biodiversity?
Answer: habitat change, climate change, invasive species, overexploitation, and pollution
Explanation:
Habitat change, climate change, invasive species, overexploitation, and pollution are the factors might contribute to a species biodiversity.
What is biodiversity?Biodiversity refers to the range of organisms—animals, plants, fungi, and even bacteria—that make up our natural world. In intricate web-like ecosystems, these different species and creatures work together to maintain equilibrium and sustain life.
Biodiversity is essential to the systems that support all life, including human life, on Earth. Without a wide range of different animals, plants, and microorganisms.
People cannot have the healthy ecosystems that we rely on to provide us with the oxygen we breathe and the food we eat. Additionally, people value nature in and of itself.
