True. Drought impacts can vary based on both the social vulnerability of the affected population and the duration and severity of the drought itself.

Social vulnerability factors such as poverty, lack of access to water resources, and limited infrastructure can exacerbate the negative impacts of drought. However, the severity and duration of the drought can also have a significant impact on water resources, agriculture, and other sectors, which can in turn affect the social and economic well-being of communities. In addition, the severity and duration of a drought can also impact the extent of its effects. For example, a short-term drought may have less impact on crops and water supplies than a long-term drought, which can lead to significant reductions in agricultural productivity and water availability. Drought impacts can also vary depending on the region affected, as different areas may have different coping mechanisms and levels of resilience in the face of drought conditions. For example, areas with more advanced water management infrastructure may be better equipped to cope with drought than areas with limited resources and infrastructure. Overall, the impacts of drought are complex and can be influenced by a variety of social, economic, and environmental factors.

During metamorphism, new mineral grains can form that are not found in the protolith. This process is called neometamorphism. Neometamorphism occurs when existing minerals recrystallize and form new minerals under the conditions of high temperature and pressure. These new minerals are typically more stable under the new conditions and can include minerals such as garnet, staurolite, and kyanite.

During metamorphism, new mineral grains can form that are not found in the original protolith, which is the rock that is subjected to the metamorphic process. This process is called neometamorphism, and it is the formation of new minerals due to the changes in temperature, pressure, and chemical environment that occur during metamorphism. Neometamorphism can occur through a variety of processes, including recrystallization, replacement, and precipitation. Recrystallization involves the rearrangement of atoms within existing minerals to form larger, more stable grains. Replacement involves the removal of one mineral and the deposition of another, either through diffusion or through hydrothermal fluids. Precipitation occurs when dissolved minerals in hydrothermal fluids are deposited in open spaces within the rock. The formation of new minerals during neometamorphism is influenced by a variety of factors, including the temperature and pressure conditions, the composition of the protolith, and the availability of fluids. Different types of metamorphism can produce different mineral assemblages, and the presence or absence of certain minerals can be used to infer the conditions under which the rock was metamorphosed Overall, neometamorphism is an important process in the formation of metamorphic rocks and the evolution of the Earth's crust.

The main carrier of heat between the warm tropics and the cold polar regions is the atmospheric circulation.

The Earth's atmosphere is an important factor in the transfer of heat because it acts as an insulator, trapping heat near the surface. The atmosphere also moves heat around the globe through the process of convection.

Warm air rises near the equator and is transported towards the poles. As the air cools, it descends near the poles, providing a return flow of air towards the equator. This circulation of air is called the Hadley cell, and helps to transport heat from the warm tropics to the cold polar regions. Other atmospheric circulations, such as the Ferrel cell and the Polar cell, also help to transport heat around the globe.

Ocean currents also play an important role in the transfer of heat, as they transport warm water from the tropics to the poles. This heat is then released into the atmosphere, helping to keep the polar regions from becoming too cold.

The ability of a rock body to store strain as frictional resistance at the faults generate stick-slip behavior, which can lead to earthquakes.

The concept of stick-slip behavior refers to the tendency of a rock body to store elastic strain energy as it is subjected to tectonic stresses, until it reaches a critical threshold where the frictional resistance along a fault is overcome and the rock suddenly slips, generating seismic waves that we experience as earthquakes. In many cases, faults are locked and do not slip continuously due to the frictional resistance between the two sides of the fault. As tectonic forces continue to act on the rock, the strain energy builds up until it reaches a critical point, at which point the fault suddenly slips, releasing the accumulated energy as seismic waves.

Elastic rebound is the release of accumulated strain energy when a rock body ruptures along a fault. As tectonic forces act upon a rock body, strain energy accumulates within the rock, causing it to deform. The rock body resists this deformation through frictional resistance along its faults.

When the accumulated strain energy exceeds the frictional resistance, the rock body ruptures along the fault. The release of strain energy causes the rock body to snap back or rebound, resulting in an earthquake. This process is called elastic rebound because the rock body returns to its original shape after the release of strain energy.

On the other hand, an orthophoto is a georeferenced and geometrically corrected aerial photograph that has been adjusted for variations in elevation and terrain, resulting in a uniform scale.

In terms of accurate horizontal measurements, an orthophoto will yield more accurate results than an uncontrolled photomosaic. This is because the orthophoto has been corrected for distortions caused by elevation changes and terrain, ensuring that horizontal distances are consistent and accurate throughout the image.nOn the other hand, an orthophoto of the same area at the same scale is a corrected aerial photograph that has been geometrically transformed to remove distortions and produce a true-to-scale image where every point has a constant scale. This means that the orthophoto will yield the most accurate horizontal measurements because it is corrected for distortions and provides a true representation of the ground surface. The correction of distortions in an orthophoto is achieved through a process called orthorectification, which involves using digital elevation models (DEMs) to correct for differences in camera position and terrain relief.
