Earthquakes are defined as the shaking of land caused due to movement of plates in the Earth's crust. It causes the destruction of houses, monuments, and leads to the bursting of volcanoes.

<h3>What is an epicenter on the map?</h3><h3 />
  • Epicenter is defined as the point directly at the position on the Earth's surface, where the earthquake started. These are represented by the stars on the map.

  • A seismograph is an instrument used to measure the motion of the ground during an earthquake.

  • The circles on the map show the effect of the earth or the waves that transmitted to which regions. The magnitude can be measured by the Richter scale.

Thus, the correct answer is Option A.

When the landmasses of the british isles and scandinavia are fitted together, mountain chains and rock types?
dedylja [7]
<span>The observation of rocks in several mountainous belts that today are separated by oceans provides evidence of continental drift.  Continental drift is the displacement of continental masses relative to each other. The Appalachian mountain belt in eastern North America ends off the coast of Newfoundland. Mountains of the same age with rocks and similar structures are found in the British Isles and Scandinavia, when these land masses come together, the mountain ranges form an almost continuous belt.</span>

list the 3 main conditions on early earth that allowed development of life, and explain how each contributed to that development

The 3 main conditions on early earth that allowed development of life,

What we can do is talk about some things that all living things on Earth share: They're carbon-based; they require water; they use energy. Perhaps most important for survival, they can grow or reproduce in some way.

<h3>What environmental factors on the early Earth permitted life to exist?</h3>

Early Hadean Earth's primary source of nutrients would have been the surface rocks, which were abundant in rarer elements like potassium and uranium as well as iron and phosphorus. Another important prerequisite is an abundance of gases that comprise substances like ammonia and methane.

<h3>The earth was extremely heated for what three reasons?</h3>

In the deep earth, heat is primarily produced by three different processes: (1) heat that was present during the planet's formation and accretion and has not yet been lost; (2) frictional heating brought on by the planet's denser core material sinking to its center; and (3) heat produced by the radioactive decay of elements.

<h3>What circumstances existed on the early Earth?</h3>

The original atmosphere probably had little oxygen and was heavy with water vapor as well as gases produced during volcanic eruptions such nitrogen and its oxides, carbon dioxide, methane, ammonia, and hydrogen. Oceans formed as Earth cooled, and a significant amount of hydrogen escaped into space.

<h3>What are the core's inner three facts?</h3>

Inner Core The inner core is a hot, heavy, and mostly iron ball. It has a 1,220 kilometer circumference (758 miles). About 5,200° Celsius (9,392° F) is the temperature inside the core. Nearly 3.6 million atmospheres are present (atm).
