-
- 9.
It leads to reduction of rainfall
- A.
Composting
- B.
Afforestation
- C.
Deforestation
- D.
Recycling
Correct Answer
C. DeforestationExplanation
Deforestation refers to the clearing or removal of trees and vegetation from an area. This process disrupts the natural ecosystem, leading to a reduction in rainfall. Trees play a crucial role in the water cycle by absorbing water from the ground and releasing it into the atmosphere through a process called transpiration. They also help to regulate the temperature and create suitable conditions for rainfall. When trees are cut down, the land becomes exposed to direct sunlight, causing increased evaporation and reducing the moisture content in the air. This ultimately leads to a decrease in rainfall in the affected area.Rate this question:

- 11.
Living thing depends on non-living things for survival
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Living things depend on non-living things for survival because non-living things provide essential resources and conditions necessary for life. For example, plants depend on sunlight, air, water, and nutrients from the soil to carry out photosynthesis and grow. Animals depend on non-living things such as air for respiration, water for hydration, and shelter for protection. Additionally, non-living things like rocks and soil provide habitats for organisms. Overall, the interdependence between living and non-living things is crucial for the survival and functioning of ecosystems.Rate this question:

Name the scale on which the magnitude of an earthquake is measured
- A.
Barometer
- B.
Seismogram
- C.
Anemometer
- D.
Richter Scale
Correct Answer
D. Richter ScaleExplanation
The correct answer is Richter Scale. The Richter Scale is used to measure the magnitude or strength of an earthquake. It was developed by Charles F. Richter in 1935 and is based on the amplitude of seismic waves recorded by seismographs. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released. The Richter Scale is widely recognized and used by scientists and researchers to assess and compare the severity of earthquakes.Rate this question:

Natural disasters usually cause great damage.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Natural disasters such as earthquakes, hurricanes, floods, and wildfires often result in significant destruction to infrastructure, property, and even loss of life. These catastrophic events can cause widespread damage to homes, buildings, roads, and other essential facilities, leading to economic, social, and environmental consequences.

Gases and ash escape with lava
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Gases and ash escaping with lava is a true statement. When a volcano erupts, it releases not only lava but also gases and ash. The intense heat of the magma causes the surrounding rocks to melt and vaporize, releasing gases such as water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. Additionally, the explosive force of the eruption can propel ash particles into the air, creating volcanic ash clouds that can travel long distances. Therefore, it is accurate to say that gases and ash escape with lava during a volcanic eruption.Rate this question:

The place of origin of an earthquake is called epicentre
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false. The place of origin of an earthquake is not called the epicenter. The epicenter is the point on the Earth's surface directly above the focus or hypocenter, which is the actual location where the earthquake originates underground. So, while the epicenter is related to the earthquake's origin, it is not the same thing as the origin itself.Rate this question:
-
- 29.
The effect of an earthquake is the minimum near the centre
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is false. The effect of an earthquake is not minimum near the center, but rather the maximum. The center, also known as the epicenter, is the point on the Earth's surface directly above the underground location where the earthquake originates, called the hypocenter. The seismic waves radiate outwards from the hypocenter, causing the most significant damage and shaking near the epicenter. As the waves travel further from the epicenter, their intensity decreases, resulting in a decrease in the effect of the earthquake. Therefore, the statement that the effect of an earthquake is minimum near the center is incorrect.Rate this question:

Flowing lava is very ______ and destroys everything in its path
Correct Answer
hotExplanation
Flowing lava is very hot and destroys everything in its path. The high temperature of lava, which can reach up to 1,200 degrees Celsius, causes it to melt and incinerate anything it comes into contact with. Its intense heat is capable of burning and melting solid objects, including rocks, trees, and buildings. The destructive power of flowing lava is primarily attributed to its extreme heat, making it a force to be reckoned with.Rate this question:

Floods are generally caused by heavy ________
Correct Answer
rainExplanation
Floods are generally caused by heavy rain because when there is excessive rainfall, the ground becomes saturated and unable to absorb all the water. This leads to an overflow of water, resulting in flooding. The heavy rain increases the water level in rivers, lakes, and other bodies of water, causing them to overflow their banks and submerge surrounding areas. Additionally, intense rainfall can also overwhelm drainage systems, further contributing to the occurrence of floods.Rate this question:
- 35.
When rainfall is delayed or scarce it leads to ________
Correct Answer
droughtExplanation
When rainfall is delayed or scarce, it can lead to drought. Drought is a prolonged period of abnormally low rainfall, resulting in a shortage of water supply for crops, livestock, and human consumption. This can have severe impacts on agriculture, ecosystems, and overall water availability, leading to water scarcity, crop failure, and even famine in extreme cases.Rate this question:

Cyclones are always accompanied by very heavy ______
Correct Answer
showersExplanation
Cyclones are characterized by intense atmospheric disturbances, resulting in strong winds and heavy precipitation. The word "showers" accurately describes the type of precipitation that is commonly associated with cyclones. These showers can be in the form of rain, hail, or even snow, depending on the temperature and location. The heavy showers are a result of the cyclone's strong updrafts, which can lift large amounts of moisture into the atmosphere, leading to significant precipitation.Rate this question:

An instrument that record duration of an earthquake
Correct Answer
SeismographExplanation
A seismograph is an instrument that is used to record the duration of an earthquake. It consists of a pendulum or a mass suspended from a frame, which remains stationary during an earthquake while the ground moves. As the ground shakes, the suspended mass or pendulum remains relatively still due to inertia, and a recording device attached to it records the movement. This allows scientists to measure the duration and intensity of the earthquake, providing valuable data for studying and understanding seismic activity.Rate this question:
- 43.
A scale that measures force of an earthquake
Correct Answer
Richter ScaleExplanation
The Richter Scale is a measurement scale used to quantify the magnitude or intensity of an earthquake. It was developed by Charles F. Richter in 1935 and is based on the logarithmic scale. The scale assigns a numerical value to the seismic energy released by an earthquake, with each whole number increase representing a tenfold increase in the amplitude of the seismic waves. The Richter Scale is widely recognized and commonly used by seismologists and geologists to compare the strength of earthquakes and assess their potential impact on structures and populations.Rate this question:
