1.
_______ is the natural science that studies the earth - its composition; the processes that shaped its surface and its history.
Correct Answer
B. Geology
Explanation
Geology is the correct answer because it is the natural science that specifically focuses on studying the Earth. It involves examining the composition of the Earth, understanding the processes that have shaped its surface over time, and investigating its geological history. Biology, Hydrology, Zoology, and Botany are all different branches of science that study living organisms and water, but they do not specifically focus on the Earth as a whole like Geology does.
2.
The art of arranging structures on the land and shaping the spaces between.
Correct Answer
A. Site Planning
Explanation
Site planning involves the art of arranging structures on the land and shaping the spaces between them. It focuses on designing the layout and organization of a site to optimize its functionality and aesthetics. This includes considerations such as the placement of buildings, roads, parking areas, landscaping, and other elements to create a harmonious and efficient environment. Site planning is an important aspect of architecture and urban design, as it ensures that the site is utilized effectively and meets the needs of its users.
3.
Rocks produced by crystallization from a liquid.
Correct Answer
C. Igneous rock
Explanation
Igneous rocks are formed through the process of crystallization from a liquid, typically magma or lava. When these molten materials cool and solidify, they form igneous rocks. This process can occur either beneath the Earth's surface, resulting in intrusive igneous rocks, or on the surface, forming extrusive igneous rocks. Examples of igneous rocks include granite, basalt, and obsidian. Sedimentary rocks are formed through the accumulation and compaction of sediments, while metamorphic rocks are formed through the alteration of existing rocks under high pressure and temperature. Gravel and limestone are types of sedimentary rocks.
4.
It is the term used to describe the composite sizes of particles in a soil sample?
Correct Answer
A. Texture
Explanation
Texture is the correct answer because it refers to the composite sizes of particles in a soil sample. Texture is determined by the proportions of sand, silt, and clay in the soil, and it affects the soil's ability to retain water, nutrients, and support plant growth.
5.
What are the three main classes of soil?
i. clay
ii. loam
iii. sand
iv. silt
v. lime
Correct Answer
A. I,ii and iii
Explanation
The correct answer is i, ii, and iii. The three main classes of soil are clay, loam, and sand. Clay is a fine-grained soil with high water and nutrient retention capacity. Loam is a balanced soil with a mixture of clay, silt, and sand, providing good drainage and fertility. Sand is a coarse-grained soil with low water and nutrient retention but good drainage. These three classes of soil have different properties that affect their fertility and suitability for plant growth.
6.
Four basic slope forms are detectable on contour maps except for?
Correct Answer
C. L-shape
Explanation
The four basic slope forms that can be detected on contour maps are straight, S-shape, concave, and convex. However, the L-shape is not one of the basic slope forms that can be observed on contour maps.
7.
_________ are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface such as the mean sea level.
Correct Answer
C. Contours
Explanation
Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface such as the mean sea level. These lines are used in topographic maps to represent the shape and relief of the land. Contours provide valuable information about the steepness of slopes, the presence of valleys or ridges, and the overall topography of an area.
8.
It is important to determine the existing availability of utilities on site in terms of adequacy and efficiency. This includes the following except for:
Correct Answer
E. Transportation
Explanation
The question asks for the option that is not included in determining the existing availability of utilities on site. The options provided are sanitary/sewage system, water supply, drainage, electric power supply, and transportation. Since the question asks for the option that is not included, the correct answer is transportation. Therefore, transportation is not considered when determining the existing availability of utilities on site in terms of adequacy and efficiency.
9.
What is aquifer?
Correct Answer
C. A permeable geological stratum or formation that can both store and transmit groundwater in significant quantities.
Explanation
An aquifer is a permeable geological stratum or formation that has the ability to store and transmit groundwater in significant quantities. It acts as an underground reservoir, allowing water to be stored within its layers and also allowing the movement of water through it. This makes aquifers an important source of water for wells and springs, as well as for sustaining rivers and lakes. Aquifers play a crucial role in the water cycle by capturing precipitation and storing it underground, making it accessible for human use and ecosystem support.
10.
The natural science that studies the waters of the earth, their occurrences, circulation and distribution, their chemical and physical properties, and their reactions to the living environment including their relation to all living things.
Correct Answer
A. Hydrology
Explanation
Hydrology is the correct answer because it is the natural science that specifically studies the waters of the earth. It focuses on various aspects such as the occurrence, circulation, and distribution of water, as well as its chemical and physical properties. Hydrology also examines how water interacts with the living environment, including its relation to all living things. Geology, geomorphology, biology, and none of the above do not encompass the comprehensive study of water like hydrology does.
