Subduction is the tectonic process which destroys crust at some convergent margins
The subduction of a cold oceanic lithosphere into a hot convective mantle is what distinguishes converging edges. The principal force causing this process is the slab pull brought on by the cold, thick rocks of the sinking oceanic lithosphere's negative buoyancy. A region on Earth where 2 or even more lithospheric plates clash is known as a convergent boundary, also referred to as a destructive boundary.
Convection cells in the mantle are what propel plate tectonics. Convection cells are produced when cool materials from the surface return to the mantle and heat produced by radioactive decay of mantle components escapes to the surface.

The image shows two different islands and the relative distance to the nearest mainland. Based on the theory of island biogeography, which of the following best predicts the effect of the introduction of an invasive species on Easter Island compared to Madagascar?answer choicesThe native species on Easter Island are more likely to survive because the island is further from the mainland.The native species on Easter Island are more likely to survive because the island is so small that there will be limited space for an invasive species to colonize.The native species on Madagascar are more likely to survive because the island is larger and provides a greater diversity of habitats and resources.The native species on Madagascar are more likely to survive because the temperature in the Indian Ocean is warmer than that of the Pacific Ocean.
Based on the theory of island biogeography, Madagascar is a larger island with a wider variety of habitats and resources, native species there have a higher chance of surviving.
What is explained by the island biogeography theory?According to the island biogeography theory, an island's size and degree of isolation have an impact on its biodiversity and species composition. There are more species on larger, less isolated islands than there are on smaller, more isolated islands. The equilibrium model of island biogeography, which forms the basis of the theory, predicts that an island's species diversity is positively correlated with its size but negatively correlated with its distance from the mainland. It consists of mountain ranges, a lake encircled by a desert, a small area of forest, or even a national park. The hypothesis offers a framework for explaining the diversity and singularity of species, both plant and animal, that can be found in a remote place.

A group or a chain of islands, Example: greater and lesser Antilles
llanos
archipelago
cash crop
pampas
Answer:
A group or a chain of islands is called archipelago.
Explanation:
The seas and oceans are not just open spaces of water with nothing interrupting them, instead they have hundreds of thousands or even millions of islands rising from them. The islands vary in size, and what can be considered as an island is still debatable, but they can be anywhere from few tens of meters to hunderds of thousands of square km.
The chains or groups of islands are called archipelago. In order to distinguish them from one another they have to have some similraties and most often they need to have the same geological history and processes that created them. An archipelago can be formed in multiple ways. Along the subduction zones there are always archipelagoes, and this is due to the volcanic activity. Another creator of archipelagoes are the hot spots because they are static but the plates move on top of them, thus draging the islands from the hot spot and new rising above it. Also, if the characteristics of the topography of an area are such that when the sea levels rise, there can be a formation of an archipelago where the lower areas will be under water while the higher places would remain above water.

Please explain why the wind curves as it moves from high pressure to low pressure and if it causes any larger wind patterns. Please answer in 3 to 5 sentences using good grammar.
High pressure system is caused when cold air sinks or subsides and Low pressure system is caused when warm air rises.
How wind is created?Wind is created when a high pressure system moves to a low pressure system, and the unbalanced air system are formed by the unequal heating within the atmosphere.
The high pressure moves into the low pressure because the low pressure system is rising air and the high pressure system is sinking air.The high pressure system will sink and fill in the void that is left by the rising low pressure systemn.
Warm air rises,creating a low pressure zone whereas, cool air sinks, creating a high pressure zone.Air that moves horizontaly between high and low pressure zones makes wind.The greater the pressure difference between the pressure zones the faster the wind moves.

in the climate system, which phase of water is most dense? a. gas b. liquid c. solid d. all have the same density.
The correct answer is b. liquid in the climate system, which phase of water is most dense.
When water is in the liquid phase, its density is highest at roughly 4 °C (39.2 °F). Since ice is more buoyant than water, it develops at the surface of bodies of water and freezes downward. Ice is a kind of solid water that is less dense than liquid water. Because of the way hydrogen bonds are oriented, ice has a lower density than water because the molecules are forced apart more. The unit of density is mass (g) per cubic millimetre (cm3). Water is least dense at 0°C and most dense at 3.98°C (freezing point). Salinity and temperature have an impact on water density. A stiff open lattice of hydrogen-bonded molecules, like a web, is created when water freezes at absolute zero degrees.

scientists divide geological time into eras and periods. the _______ is most inclusive, and the boundaries are based on _______.
A wind shift from south or southwest to northwest is commonly associated with the passage of a ________ front.
A wind shift from the south or southwest to the northwest is commonly associated with the passage of a cold front.
A cold front is the leading edge of a cooler mass of ground-level air that replaces a warmer mass of air in a conspicuous surface trough of low pressure. The cold front advection pattern, also known as the cyclone's dry "conveyor belt" flow, which is to the west in the Northern Hemisphere and to the east in the Southern Hemisphere, is where it frequently forms at the leading edge of extratropical cyclones.
The difference in temperature between the two sides of the barrier may exceed 30 °C (54 °F). If there is enough moisture in the air, rain can fall along the boundary thunderstorms may form along the frontal zone. If instability is weak, a large shield of rain may move in behind the front; the evaporative cooling of the rain may increase the temperature difference across the front. Cold fronts are at their strongest during the transitional seasons of fall and spring, and at their weakest during the summer.

the presence of meltwater at the bottom of a glacier can increase its rate of movement. question 36 options: true false
Answer:
True
Explanation:
True. The presence of meltwater at the bottom of a glacier can increase its rate of movement, also known as its "flow velocity." When water collects at the base of a glacier, it can act as a lubricant, allowing the glacier to move more easily over the underlying land. This can cause the glacier to flow more quickly and potentially to advance or retreat more rapidly than it otherwise would. The amount of meltwater present at the base of a glacier can vary depending on factors such as the temperature and the amount of snow and ice present, and can have a significant impact on the glacier's movement and overall behavior.
imagine yourself as a farmer owning land which is infertile.
How would uh convert it into a fertile farmland
Answer:
Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.
Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.
Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.
Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.
Animals: Animals playing a key role in regeneration. Chickens, bullocks and cows were integrated in the everyday activities. The chickens provide eggs and their excreta enriched compost. Bullocks are used for ploughing and sowing.
Local crops: Local crops such as millets, pigeon peas, green grams are also grown. Seasonal vegetables from the garden such as brinjals, curry leaves, cluster beans, rosella plants are used for daily consumption and will also be served to the 600 participants at the IPC.
