What type of boundary is made by the Mariana Trench?

Convergent
Reformation
Divergent
Transformation

Correct Answer

A. Convergent

Explanation

The Mariana Trench is formed by a convergent boundary. Convergent boundaries occur when two tectonic plates collide, causing one plate to be forced beneath the other in a process called subduction. In the case of the Mariana Trench, the Pacific Plate is subducting beneath the Philippine Plate, creating a deep trench in the ocean floor. This process is responsible for the formation of some of the deepest parts of the Earth's oceans, including the Mariana Trench, making the answer "Convergent" the correct choice.

How old is the sun estimated to be?

5,600,000,000 Years Old
6,500,000,000 Years Old
6,400,000,000 Years Old
4,600,000,000 Years Old

Correct Answer

A. 4,600,000,000 Years Old

Explanation

The sun is estimated to be 4,600,000,000 years old. This estimate is based on scientific research and analysis of various data, such as the age of the oldest rocks on Earth and the rate at which the sun is burning its fuel. By studying these factors, scientists have determined that the sun formed about 4.6 billion years ago, around the same time as the formation of our solar system.

Who discovered the Gulf Stream?

Thomas Jefferson
Benjamin Franklin
Frederick Dover
Matthew Maury

Correct Answer

A. Benjamin Franklin

Explanation

Benjamin Franklin is credited with discovering the Gulf Stream. He conducted a series of experiments and observations during his time as Deputy Postmaster General for the American colonies. Franklin noticed that mail ships traveling from the United States to Europe took significantly less time than ships traveling in the opposite direction. Through his observations and analysis, Franklin concluded that there was a strong ocean current flowing from the Gulf of Mexico to the North Atlantic, which he named the Gulf Stream. His discovery of this powerful current had a significant impact on navigation and trade routes across the Atlantic Ocean.

What mineral makes both sapphires and rubies when cut and polished?

Apatite
Fluorite
Corundum
Topaz

Correct Answer

A. Corundum

Explanation

Corundum is the correct answer because it is the mineral that makes both sapphires and rubies when cut and polished. Sapphires and rubies are both gem varieties of corundum, with sapphires being blue and rubies being red. Corundum is a very hard mineral, second only to diamond, and is composed of aluminum oxide. Its crystal structure and impurities determine its color, with iron and titanium causing blue sapphires and chromium causing red rubies.

What is the origin of dinoflagellates?

Plankton
Algae
Flowering Plants
Trees

Correct Answer

A. Algae

Explanation

Dinoflagellates are single-celled organisms that belong to the group of algae. They are characterized by their ability to photosynthesize and their flagella, which they use for movement. Algae, including dinoflagellates, are aquatic organisms that can be found in both freshwater and marine environments. They play a crucial role in the food chain as primary producers, providing food for other organisms. Therefore, the correct answer is Algae.

Whose calculation of the size of the earth's diameter was almost exact?

Socrates
Aristotle
Eratosthenes
Aristarchus

Correct Answer

A. Eratosthenes

Explanation

Eratosthenes' calculation of the size of the earth's diameter was almost exact. He used a method involving the measurement of shadows at different locations and angles to estimate the circumference of the earth. His calculation was remarkably close to the actual value, considering the limited technology and resources available at that time. This demonstrates Eratosthenes' advanced knowledge and understanding of geometry and astronomy.

Gold, silver, lead, and copper exhibit the properties of which of the following crystal systems?

Tetragonal
Cubic
Hexagonal
Trigonal

Correct Answer

A. Cubic

Explanation

Gold, silver, lead, and copper exhibit the properties of the cubic crystal system. The cubic crystal system is characterized by a three-dimensional arrangement of atoms or ions in a lattice structure, with equal sides and angles. This system is known for its symmetry and regularity, which is reflected in the properties of these metals.

How was the 12-mile limit of a country's boundary set?

Firing Of Cannon Balls From A Ship To The Shore
Firing Of Cannon Balls From The Shore
Escape Velocity Of A Windjammmer
The Distance A Cutter Could Sail In 15 Minutes

Correct Answer

A. Firing Of Cannon Balls From The Shore

Explanation

The 12-mile limit of a country's boundary was set by the firing of cannon balls from the shore. This practice, known as "cannon-shot rule," was used in the past to determine the extent of a country's territorial waters. The idea was that the range of a cannon shot from the shore would mark the boundary of a country's control over its coastal waters. Therefore, the firing of cannon balls from the shore was used as a method to establish the 12-mile limit of a country's boundary.
