1.
Which of these is not an endogenous process?
Correct Answer
D. Continental crust
Explanation
Continental crust is not an endogenous process because it is a part of the Earth's outer layer and is formed through various geological processes such as plate tectonics and volcanic activity. Endogenous processes refer to internal processes within the Earth, such as volcanic eruptions and earthquakes, which are caused by movements and interactions of the Earth's tectonic plates. Continental crust, on the other hand, is a result of these endogenous processes and is not an active process in itself.
2.
Which of these is not associated with denudation?
Correct Answer
D. Abrasion
Explanation
Abrasion is not associated with denudation. Denudation refers to the overall process of wearing away and removing the Earth's surface materials, including weathering, erosion, and mass movement. Abrasion, on the other hand, specifically refers to the mechanical wearing away of rock surfaces by friction and impact of particles or other rocks. While abrasion is a form of erosion, it is not considered a primary process in denudation, which involves a combination of various geological processes.
3.
Which of these is not a factor affecting weathering?
Correct Answer
A. Weathering
Explanation
Weathering is not a factor affecting weathering. Weathering refers to the process by which rocks and minerals are broken down into smaller pieces by physical, chemical, and biological processes. It is the result of other factors such as climate, biosphere, and tectonic activity. Climate, including temperature and precipitation, plays a significant role in weathering as it can cause expansion and contraction of rocks. The biosphere, which includes plants and animals, can contribute to weathering through their actions such as root growth and burrowing. Tectonic activity, such as earthquakes and volcanic eruptions, can also lead to weathering by exposing rocks to the elements.
4.
Which of these is not a denudation estimate?
Correct Answer
C. Mass load
Explanation
Denudation refers to the process of wearing away or eroding the Earth's surface. It includes the transportation of sediments by various means. Bed load, dissolved load, and suspended load are all types of sediment loads that are transported by water. However, mass load is not a term used to describe the transportation of sediments. Therefore, it is not a denudation estimate.
5.
How many are the seasons that occur on earth?
Correct Answer
A. Four
Explanation
There are four seasons that occur on Earth: spring, summer, autumn, and winter. Each season is characterized by different weather patterns and temperatures. Spring is a season of growth and renewal, with blooming flowers and warmer temperatures. Summer is the hottest season, with longer days and higher temperatures. Autumn is known for its colorful foliage and cooler temperatures. Winter is the coldest season, with shorter days and lower temperatures, often accompanied by snow and ice. These four seasons occur due to the tilt of Earth's axis and its orbit around the sun.
6.
Which of these is not a weather phenomena?
Correct Answer
B. Precipitation
Explanation
Precipitation refers to any form of water that falls from the atmosphere to the Earth's surface. It includes rain, snow, sleet, and hail. Therefore, precipitation is a weather phenomenon. Rain, snow, and fog are all examples of weather phenomena as they are natural occurrences in the atmosphere.
7.
Which of these is not a natural disaster characterized by the violebt wind?
Correct Answer
C. Volcanic eruption
Explanation
A volcanic eruption is not characterized by violent wind. While volcanic eruptions can release ash, gas, and lava, they do not typically involve strong winds. Typhoons, hurricanes, and tornadoes, on the other hand, are all natural disasters that are characterized by violent winds. Typhoons and hurricanes are large tropical cyclones that form over warm ocean waters, while tornadoes are violent rotating columns of air that form in severe thunderstorms.
8.
Which of these refers to the weather of a place over a long period of time?
Correct Answer
B. Climate
Explanation
Climate refers to the weather of a place over a long period of time. It is the average weather conditions, including temperature, precipitation, humidity, and wind patterns, that occur in a particular region over many years. Climate helps to determine the overall weather patterns and conditions that are characteristic of a specific area.
9.
How many components are in the climate system?
Correct Answer
A. Five
Explanation
The climate system is composed of five main components: the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere. These components interact with each other and with external factors, such as solar radiation, to determine the Earth's climate patterns and changes. Each component plays a crucial role in the overall functioning of the climate system, and understanding their interactions is essential for studying and predicting climate behavior.
10.
Which of these is not a component of the climate system?
Correct Answer
C. Stratosphere
Explanation
The stratosphere is not a component of the climate system because it is part of the Earth's atmosphere, specifically the second layer above the surface. The climate system is composed of the biosphere (all living organisms), hydrosphere (water in all its forms), and lithosphere (the solid outer layer of the Earth). The stratosphere, although important for atmospheric processes, is not directly involved in the climate system and its interactions.
