1.
The first era in which the Earth existed is what is known as the ______ Eon.
Correct Answer
A. Hadean
Explanation
The correct answer is Hadean. The Hadean Eon is the first era in which the Earth existed, dating back to approximately 4.6 billion years ago. During this time, the Earth was still forming and undergoing intense volcanic activity, with a harsh environment unsuitable for life as we know it. The Hadean Eon is named after the Greek god Hades, representing the fiery and inhospitable conditions of the early Earth.
2.
The most common theory, known as the “Giant Impact Hypothesis" proposes that the Moon originated after a body the size of Mars (sometimes named Moon).
Correct Answer
B. False
Explanation
The explanation for the answer "False" is that the statement is incorrect. The most common theory, known as the "Giant Impact Hypothesis," suggests that the Moon originated after a body the size of Mars collided with Earth. It does not propose that the Moon originated after a body the size of Mars, sometimes named Moon. Therefore, the answer is false.
3.
Oxygen producing Bacteria were formed in:
Correct Answer
C. Proterozoic Eon
Explanation
During the Proterozoic Eon, which lasted from around 2.5 billion to 541 million years ago, oxygen-producing bacteria, also known as cyanobacteria, emerged. These bacteria were capable of photosynthesis, converting sunlight, water, and carbon dioxide into oxygen and organic compounds. This marked a significant milestone in Earth's history, as the release of oxygen into the atmosphere had a profound impact on the development of life on our planet. The Proterozoic Eon was a crucial period in the evolution of Earth's biosphere, leading to the eventual rise of complex multicellular organisms.
4.
________ devised the global grid of parallels and meridians.
Correct Answer
Roman
Explanation
The correct answer is Roman. The Romans were responsible for devising the global grid of parallels and meridians. They developed a system of dividing the Earth's surface into a grid of lines running north-south (meridians) and east-west (parallels) to create a coordinate system for navigation and mapping. This grid system, known as the Roman grid, laid the foundation for modern cartography and continues to be used today.
5.
Who explored apparent latitudinal variations in climate?
Correct Answer
D. Romans
Explanation
The Romans explored apparent latitudinal variations in climate.
6.
____________ is known as father of Geography.
Correct Answer
B. Eratosthenes
Explanation
Eratosthenes is known as the father of Geography because he was the first person to use the term "geography" and to create a comprehensive system for describing and mapping the Earth. He calculated the circumference of the Earth, created one of the earliest world maps, and divided the Earth into five climatic zones. His work laid the foundation for the development of geography as a scientific discipline.
7.
Angular distance towards north or south of the equator is known as:
Correct Answer
A. Latitude
Explanation
Latitude refers to the angular distance towards the north or south of the equator. It is measured in degrees and ranges from 0° at the equator to 90° at the poles. Longitude, on the other hand, refers to the angular distance towards the east or west of the prime meridian. Grid is a term used to refer to a network of horizontal and vertical lines used to determine coordinates on a map. Therefore, the correct answer is Latitude as it specifically relates to the distance from the equator.
8.
180 degree longitude is also known as international date line.
Correct Answer
A. True
Explanation
The statement is true because the 180 degree longitude is indeed known as the international date line. This imaginary line on the Earth's surface is located at approximately 180 degrees longitude and serves as the boundary between two consecutive calendar days. When crossing this line from east to west, the date changes by one day. It is an important marker for timekeeping and helps maintain a consistent global time system.
9.
The study of spatial variation, of how and why things differ from place to place on the surface of the earth is known as ________.
Correct Answer
geography
Explanation
The study of spatial variation, of how and why things differ from place to place on the surface of the earth is known as geography. Geography examines the physical characteristics of the Earth's surface, such as landforms, climate, and ecosystems, as well as the human activities and patterns that occur within different regions. It seeks to understand the relationships between people and their environment, and how these interactions shape the world we live in. By studying geography, we can gain insights into the diverse cultures, landscapes, and processes that exist on our planet.
