1.
All of these are branches of Hydrology except...
Correct Answer
D. Human Hydrology
Explanation
Human Hydrology is not a branch of hydrology because it focuses on the social, economic, and political aspects of water management rather than the physical properties and processes of water. Hydrogeology studies the distribution and movement of groundwater, Ecohydrology examines the interactions between ecosystems and water, and Chemical Hydrology investigates the chemical composition and behavior of water.
2.
One of these is the study of interaction between organisms and hydrological cycle?
Correct Answer
B. Ecohydrology
Explanation
Ecohydrology is the study of the interaction between organisms and the hydrological cycle. It focuses on understanding how water availability and quality affect ecosystems, and how ecosystems, in turn, influence the movement and distribution of water. This field of study examines the complex relationships between hydrological processes and ecological systems, including the impact of human activities on these interactions. By studying ecohydrology, scientists can gain insights into the sustainable management of water resources and the conservation of ecosystems.
3.
In the first century, who described the philosophical theory of the hydrologic cycle?
Correct Answer
D. Marcus Vitruvius
Explanation
Marcus Vitruvius was a Roman architect and engineer who lived during the first century BC. He wrote a book called "De Architectura" (On Architecture) in which he described various theories and principles of architecture, including the hydrologic cycle. In this book, he discussed the movement of water through evaporation, condensation, and precipitation, and how it affects the Earth's climate and water supply. Vitruvius' work on the hydrologic cycle was groundbreaking for its time and laid the foundation for our modern understanding of this natural phenomenon.
4.
What process brings the deep cold ocean current up to the surface?
Correct Answer
C. Convection Currents
Explanation
Convection currents are responsible for bringing the deep cold ocean current up to the surface. Convection is the transfer of heat through the movement of fluids, and in this case, it refers to the upward movement of the cold water due to differences in temperature and density. As the cold water sinks and becomes denser, it is replaced by warmer water from the surface, creating a continuous cycle of circulation. This process helps to distribute heat and nutrients throughout the ocean, affecting global climate patterns and marine ecosystems.
5.
About how much of the Earth's surface is covered with water?
Correct Answer
B. 3/4
Explanation
Approximately 3/4 of the Earth's surface is covered with water. This is a well-known fact and is supported by scientific data. The Earth is often referred to as the "Blue Planet" because of its abundant water bodies, including oceans, seas, lakes, and rivers. The remaining 1/4 of the Earth's surface is comprised of landmasses. The vast amount of water on Earth plays a crucial role in regulating the planet's climate, supporting various ecosystems, and providing a habitat for countless marine species.
6.
Who is considered the father of Hydrology?
Correct Answer
C. Robert E. Horton
Explanation
Robert E. Horton is considered the father of Hydrology because he made significant contributions to the field. He developed the Hortonian overland flow model, which describes the movement of water across the land surface. This model revolutionized the understanding of surface runoff and infiltration processes. Horton's work laid the foundation for modern hydrological studies and his research continues to be influential in the field.
7.
What is the flow of land into the body of water?
Correct Answer
B. Run-off
Explanation
Run-off refers to the movement of water from land surfaces into bodies of water such as rivers, lakes, and oceans. It occurs when precipitation, such as rain or snow, exceeds the ability of the land to absorb it. Instead, the excess water flows over the surface, carrying with it sediments, pollutants, and nutrients. This flow of water plays a crucial role in the water cycle and the overall health of aquatic ecosystems.
8.
One of these is not a subdivision of Hydrology.
Correct Answer
D. Hydrometeorology
Explanation
Hydrometeorology is the study of the water cycle and its interaction with the atmosphere, including the study of precipitation, evaporation, and atmospheric moisture. It focuses on the meteorological aspects of water, rather than the physical properties or distribution of water on Earth's surface or underground. In contrast, surface water hydrology deals with the study of water on the Earth's surface, hydrogeology focuses on the study of groundwater, and marine hydrology deals with the study of water in the oceans. Therefore, hydrometeorology is the only option that does not fall under the subdivision of hydrology.
9.
Hydrologist studies all of these except...
Correct Answer
D. Water carbon
Explanation
A hydrologist is a scientist who studies the distribution, movement, and quality of water on Earth. They analyze various aspects related to water, such as the water cycle, water resources, and environmental watershed sustainability. However, water carbon is not a term or concept typically studied by hydrologists. Carbon is more commonly associated with the carbon cycle and its impact on climate change, which falls under the domain of climate scientists or environmental scientists.
10.
Which of these branches is the study of flow of groundwater?
Correct Answer
A. Hydrogeology
Explanation
Hydrogeology is the study of the flow, distribution, and quality of groundwater. It focuses on understanding the movement of water through underground aquifers and the geological formations that contain and control the flow of groundwater. This branch of geology is essential for managing and protecting water resources, assessing the potential for groundwater contamination, and designing systems for groundwater extraction. Hydrogeologists use various methods such as drilling, sampling, and modeling to study the behavior of groundwater and its interaction with surface water and the environment.
