The advantages are that these sources can never run out because these sources are continuously filled by nature and the generation process is pollution-free, and production can be increased on demand. The disadvantages are their geographic limitations and low-efficiency levels.

Renewable energy is any form of energy derived from natural sources and can be replenished repeatedly. It is also often called sustainable energy. These sources are the opposite of fossil fuels, like coal and gas, which are finite energy sources.

Advantages:

Wind farms can help in rural and remote areas development as they too will have green electricity.

Building large dams and using turbines might be expensive, but it will produce a great amount of electricity.

Solar energy is not dependent on other sources of energy and reduces electricity costs.

Despite fossil fuels that are always subject to disagreement and wars between countries, we can collectedly gain control of renewable energy sources.

Disadvantages:

Their unequal distribution creates difficulties in acquiring them.

These sources are natural forces that are strongly dependent on the weather condition. Therefore, when you have bad weather conditions, renewable energy technologies such as solar cells will be of less use.

Their initial cost is high and sometimes uneconomical, considering the amount of energy we can get from these technologies.

Overall, the advantages of using renewable energy sources outweigh the disadvantages. Although the initial cost of organizing a network of renewable technologies might be higher, over time, the expenses will be offset.

Ozone depletion potential (ODP) is a measure of the potential of a substance to cause ozone depletion. The ODP value of a compound is compared to that of CFC-11 and is a ratio of the amount of ozone depletion resulting from the chemical compared to the amount caused by the same mass of CFC-11. ODP values range from zero to one.

CFCs and other halocarbons are the most damaging chemicals to the ozone layer, with ODP values in the range of 0.5 to 1.0. ODP is an important concept in the field of environmental science, as the depletion of the ozone layer can have serious consequences for human health and the environment. It can lead to increased levels of UV radiation, which can cause skin cancer, cataracts, and other health problems. ODP is used to compare the environmental impact of different chemicals and to help scientists and policymakers make informed decisions about which substances to use and which to avoid.

In the 2nd special reading, it was proposed that the 20,000-year climate cycle in East Africa is driven by changes in the Earth's orbit and tilt.

The 20,000 year climate cycle in East Africa, which ranges from extreme aridity to very wet conditions, is believed to be driven by changes in the Earth's orbit and tilt. This cycle is known as the precession cycle, which refers to the slow wobbling of the Earth's axis as it spins. This wobbling causes changes in the amount and distribution of solar radiation that reaches different parts of the Earth, which in turn affects the climate. Specifically, during periods of low tilt, East Africa experiences more direct sunlight, which leads to more evaporation and rainfall. During periods of high tilt, East Africa experiences less direct sunlight, which leads to drier conditions. Overall, these changes in the Earth's orbit and tilt play a significant role in shaping the climate of East Africa over long time scales.

No, the above statement is false. In the Northern Hemisphere, the water surface of the open ocean moves approximately 45° to the right of the wind.

This phenomenon is known as the Ekman transport. Due to the Coriolis effect, which deflects moving objects to the right in the Northern Hemisphere, the net movement of water particles is at an angle of about 45° to the right of the wind direction. This means that the wind pushes the surface water at an angle, and the resulting movement of water is slightly to the right of the wind direction. It is important to note that this 45° angle is an average and can vary depending on factors such as wind speed and ocean depth.

Answer:

In Bangladesh, the vegetation is predominantly tropical and sub-tropical, with a mix of forests, grasslands, and wetlands. The country has a diverse range of vegetation types, including the Sundarbans mangrove forest, which is the largest mangrove forest in the world, tropical rainforests, and deciduous forests.

The country's climate is tropical, with a monsoon season from May to November and a dry season from December to April. The high humidity and heavy rainfall during the monsoon season create favorable conditions for the growth of lush vegetation, including forests, grasslands, and wetlands.

The Sundarbans mangrove forest, which is found in the southwestern region of Bangladesh, is a unique ecosystem that is adapted to the brackish water of the delta region, as well as the monsoon season flooding. The mangrove trees have evolved specialized roots that help them to survive in the humid and waterlogged conditions of the delta.

In the drier regions of the country, deciduous forests are more common, with trees that lose their leaves during the dry season to conserve water. The grasslands and wetlands in Bangladesh are also important habitats for wildlife and bird species. Overall, the country's vegetation is strongly influenced by its tropical climate, which supports a wide range of plant

False. Relative humidity is usually highest in the cool early-morning hours and decreases throughout the day to its lowest values in the cool early-evening hours due to temperature changes affecting the air's moisture-holding capacity.

Throughout the day, as temperatures rise, the air can hold more moisture, leading to a decrease in relative humidity. This decrease is often most noticeable during the afternoon when temperatures are at their peak. The warm air has a higher capacity to hold moisture, causing the relative humidity to drop. However, it's important to note that this pattern can vary depending on the specific weather conditions, geographical location, and seasonal factors.

During the cool early-evening hours, as temperatures start to decrease again, the air's capacity to hold moisture decreases, and relative humidity tends to rise. This pattern continues into the night, with relative humidity reaching its highest values again during the cool early-morning hours. Overall, the diurnal variation of relative humidity is influenced by the temperature changes throughout the day.

The seafloor in the Atlantic Ocean exhibits a distinctive pattern of ages, with the youngest rocks found along the mid-ocean ridge and progressively older rocks as you move away from it.

The mid-ocean ridge, which is a divergent plate boundary, runs down the center of the Atlantic Ocean, separating the oceanic plates on either side and creating new crust through seafloor spreading.

As magma rises to the surface along the mid-ocean ridge, it cools and solidifies, forming new crust. This process, known as seafloor spreading, pushes the existing seafloor away from the ridge and creates a symmetrical pattern of crust on either side. The result is a band of relatively young seafloor rocks centered along the ridge and progressively older rocks farther away.

When rocks are Unconformity , several adjacent layers were deposited without interruption.

Unconformity is a type of rock discontinuity in which sedimentary rocks are not deposited on top of each other in a continuous sequence. Instead, a layer of sedimentary rock is overlain by a layer of sedimentary rock that is younger or older than the one below it.

This occurs when the underlying layer of sedimentary rock is eroded or uplifted due to tectonic or other geological activity. Unconformities may also occur when sedimentary rocks are eroded and the area is then submerged and sedimentation resumes. The unconformity marks the boundary between the two sedimentary sequences.

Unconformities are important markers of geological history as they provide evidence of changes in the environment and tectonic activity that occurred between the two sedimentary sequences.
