what would you expect weather to be like on the eastern coast of australia if the western coast of south america were experiencing unusually warm, wet weather?
If the western coast of South America is experiencing unusually warm and wet weather, you would expect the weather on the eastern coast of Australia to be cooler and drier. This is due to the El Niño-Southern Oscillation (ENSO) phenomenon, which affects global weather patterns.
What is El Niño-Southern Oscillation?
El Niño-Southern Oscillation is a phenomenon that occurs when the ocean temperatures in the equatorial Pacific Ocean change from their normal temperatures. It occurs every three to seven years and lasts between one and two years.
The change in ocean temperature causes the trade winds, which usually blow from east to west, to slow down or reverse direction. When the trade winds slow down or reverse, it causes a buildup of warm water in the eastern Pacific Ocean, leading to El Niño. During an El Niño, the Pacific Ocean's warm surface waters move eastward towards South America, leading to unusually warm and wet weather on the western coast of South America.On the other hand, when the trade winds are stronger than usual, the ocean currents become stronger, leading to colder ocean temperatures in the eastern Pacific Ocean. This is known as La Niña, and it results in cooler and drier weather on the western coast of South America.
What is the effect of El Niño-Southern Oscillation on Australia?
Australia's weather patterns are also affected by El Niño-Southern Oscillation. During an El Niño event, Australia typically experiences drier and warmer weather conditions, especially in the eastern parts of the country. However, during a La Niña event, Australia typically experiences wetter and cooler weather conditions.El Niño-Southern Oscillation is a significant weather phenomenon that affects global weather patterns, including the weather on the eastern coast of Australia.

black smokers in the bottom of the ocean are evidence of active hydrothermal metamorphism. group of answer choices true false
Yes, black smokers in the bottom of the ocean are evidence of active hydrothermal metamorphism. Hydrothermal metamorphism is a process of geologic transformation that occurs when hot, mineral-rich water circulates through rock formations.
Black smokers are large chimney-like structures created by hydrothermal vents, which form when the hot water mixes with cold seawater. The chimneys are composed of metal-rich minerals that are created when the hot water interacts with the ocean floor. These minerals give the chimneys a black color, thus the name black smoker.
The presence of these structures in the ocean floor indicates that hydrothermal metamorphism is still alive and well. The mineral-rich water that is released from the chimneys is also responsible for the formation of new minerals and the alteration of existing ones. Thus, the presence of black smokers is an indication of active hydrothermal metamorphism.

the melting of ice sheets from land masses is of greater concern to scientists than the melting of icebergs because
The melting of ice sheets from land masses is of greater concern to scientists than the melting of icebergs because the excess water flows into the oceans and causes the sea levels to rise which have catastrophic consequences on coastal populations and ecosystems.
Ice sheets are larger and more widespread than icebergs, making them more likely to impact global sea levels. Ice sheets are made of freshwater that has been frozen for thousands of years and they are part of the Greenland and Antarctic ice caps. As they melt, the excess water flows into the oceans and causes the sea levels to rise. This can have catastrophic consequences on coastal populations and ecosystems. In contrast, icebergs are smaller and more localized. Melting of icebergs does not significantly contribute to global sea levels, but it does affect the balance of fresh and salt water in the oceans.
Overall, melting of ice sheets has the greater potential to cause widespread, long-term damage. Melting of ice sheets from land masses can cause disruption to ecosystems, sea level rise, and coastal flooding. On the other hand, melting of icebergs only impacts the salinity of the ocean, which has less far-reaching implications.

what element is missing from this diagram of the rock cycle? compacting and cementing sediment sedimentary rock weathering and erosion
The element that is missing from the diagram of the rock cycle is metamorphism.
What is the rock cycle?
The rock cycle is a natural process by which rocks are transformed into other forms. In simpler terms, the rock cycle is the transformation of one type of rock into another type of rock via numerous geological processes.
The rock cycle is composed of three main phases: Igneous rocks that form from molten rocks, Sedimentary rocks that form from weathered and eroded debris and Metamorphic rocks that form from heat and pressure.
What is metamorphism?
Metamorphism is a geological process that involves the transformation of pre-existing rocks into a different kind of rock.
Metamorphism can be caused by an increase in temperature, pressure, or both. In metamorphism, heat and pressure together cause changes in the mineral structure of the rocks, leading to the formation of metamorphic rocks.
In summary, the correct answer is Metamorphism is missing from the diagram of the rock cycle.

which rock type most suggests possible deposition by energetic mountain streams? group of answer choices shale conglomerate greywacke well-sorted, quartz-rich sandstone
The rock type that most suggests possible deposition by energetic mountain streams is greywacke.
What's GreywackeGreywacke is a sedimentary rock composed of coarse-grained quartz and feldspar fragments, commonly mixed with clay and silt. It forms when eroded materials are transported by high-energy streams, such as mountain streams, and deposited in a deep-water environment.
It is characterized by sharp angular grains and is usually poorly sorted. Common minerals in greywacke include quartz, feldspar, mica, and accessory minerals like magnetite and tourmaline.
In addition, greywacke is often found with shale, conglomerate, and well-sorted quartz-rich sandstone, which are all sedimentary rocks formed in a similar manner.
