Under what conditions do pillow lavas form?

Answers

Answer 1

Pillow lavas are lava lobes that are bulbous, spherical, or tubular in shape. They arise during relatively low effusion rate eruptions.

Pillow basalt is a volcanic igneous rock that occurs when basaltic lava erupts underwater. The pillow-shaped bodies are formed by the quick cooling of the lava by cold water on all sides, which can then break open and extrude more of the hot lava from within.

Elongate lava pillow mounds are created by repeated oozing and cooling of molten basalt. First, a flexible glassy crust forms around the newly extruded lava, expanding the pillow. The pressure is then increased until the crust fractures and new basalt extrudes like toothpaste, making another pillow.

Answer 2

To answer, under what conditions do pillow lavas form.

Pillow lavas form when molten lava is rapidly cooled and solidified as it comes into contact with water. This typically occurs in underwater volcanic eruptions, where lava is ejected from a vent on the seafloor and encounters the surrounding seawater.

The cooling of the lava is so rapid that it forms a solid outer layer, which cracks and fractures as more lava flows out from the vent. This creates pillow-shaped structures that can stack on top of each other to form extensive lava fields on the seafloor.

So, the main condition for the formation of pillow lavas is the interaction between molten lava and water, particularly in underwater volcanic eruptions.

compare the movement of ice in valley glaciers to movement of water in a stream? include in your discussion the velocity profile, the erosion each causes, the competence of each, and the types of deposits each leaves?

Answers

Valley glaciers and streams differ in their movement and the effects they have on the surrounding environment. In terms of velocity profile, streams have a relatively uniform flow with faster-moving water at the center and slower-moving water at the edges. Valley glaciers, on the other hand, move slower at the top and faster at the bottom due to the effect of gravity.

Erosion caused by valley glaciers is more extensive and abrasive than that caused by streams. The sheer weight of ice and the debris it carries can carve out valleys and create deep crevasses. In comparison, streams typically erode through hydraulic action, which involves the force of water pushing against the surface of rocks and sediment.

Competence, or the ability to transport sediment, is higher for streams than valley glaciers. This is because streams have a higher flow rate and can carry larger sediment particles. Valley glaciers, on the other hand, have a lower flow rate and are better at carrying finer particles.

The midlatitude steppe climate supports mostly which type of agriculture?
A) Midlatitude steppe does not support any kind of agriculture.
B) oasis and irrigated agriculture
C) pastoral nomadism
D) some other kind of agriculture not listed
E) dry farming

Answers

The midlatitude steppe climate supports mostly pastoral nomadism type of agriculture.

Nomadic pastoralism is a type of pastoralism in which cattle is herded in search of new pastures to feed on. In contrast to transhumance, where seasonal pastures are set, true nomads pursue an unpredictable pattern of travel. Nomadic pastoralism is frequent in areas with little arable land, particularly in the steppe plains north of Eurasia's agricultural zone.

Full pastoralism necessitated the Secondary Products Revolution, during which animals were employed for wool, milk, riding and traction, in addition to meat. Herds must be relocated if the grass is insufficient, resulting in nomadism. While some people live a nomadic lifestyle exclusively, others spend the winter in winter camps and move their herds into the steppe during the summer.

Answers

If the sun suddenly became a little brighter, it would warm the world a little. However, this would also trigger other changes in the earth system that could either amplify or oppose the warming. These changes are known as feedbacks, and they can have a significant impact on the final outcome.

In this case, we would expect other things to change in the earth system, and these feedbacks would amplify the warming from the sun to some extent. However, it is unlikely that these feedbacks would cause the earth to warm up so much that life would become impossible. Instead, the earth would end up somewhat warmer than before the sun changed.

It is important to note that there are many different feedbacks in the earth system, and their effects are complex and not yet fully understood. Therefore, it is difficult to predict with certainty what would happen if the sun became a little brighter. However, based on our current knowledge, we can say that some warming would occur, and this would be amplified to some extent by feedbacks in the earth system.

The geographer found that farmers in China practised intensive farming near villages with land improvement methods, but farther from villages, land degradation occurred due to increased pesticide use and fewer conservation practices.

According to the geographer's research, farmers in China engaged in intense farming close to villages, cultivating territories both near and distant from the community. The regional variation in agricultural techniques, however, led to land development techniques like adding organic material near the community.

Rapid climate changes are relatively ______ and can happen when ______ feedback loops dominate the system.A. common; positiveB. common; negativeC. uncommon; negativeD. uncommon; positive

Answers

Rapid climate changes are relatively uncommon and can happen when positive feedback loops dominate the system. Positive feedback loops occur when a change in one part of the climate system amplifies and accelerates further changes, creating a self-reinforcing cycle.  Option D.

For example, when Arctic sea ice melts, it exposes dark ocean water, which absorbs more sunlight and warms up faster, leading to more melting and less ice.

This process can rapidly accelerate and cause significant changes in the climate. While climate changes have occurred naturally throughout Earth's history, the current rate and extent of change are largely attributed to human activities, such as burning fossil fuels and deforestation.

These activities release large amounts of greenhouse gases into the atmosphere, which trap heat and contribute to global warming. As a result, it is important for us to reduce our carbon footprint and mitigate the impacts of climate change to prevent further disruptions to our planet's delicate ecosystems.

The measurement of radioactive parent atoms and stable decay products (daughter atoms) in a rock allow for what to be determined?

Answers

The measurement of radioactive parent atoms and stable decay products (daughter atoms) in a rock allow for the determination of the age of the rock through a process known as radiometric dating.

This technique utilizes the known rate of decay of certain isotopes within the rock to calculate the amount of time that has passed since the rock formed. By comparing the ratio of parent atoms to daughter atoms, scientists can determine the age of the rock and gain insight into geological processes and the history of the Earth.

The phrase that best sums up geological processes throughout history is "geological process of Earth's formation is cyclical."

The historical history of Earth's formation reveals that it was formed by a number of significant geological events, some of which are currently changing the Earth's surface.

Answers

63% percentage more nitrogen would be saved annually by using reduced tillage rather than conventional tillage. The correct Option is A

Reduced tillage involves disturbing the soil less compared to conventional tillage, which means that the nitrogen present in the soil is not lost due to excessive tillage. The correct Option is A

Nitrogen is an essential nutrient for plant growth and development, and farmers often use nitrogen fertilizers to supplement the soil.

However, excessive tilling can cause nitrogen to leach out of the soil, which means that the farmer will have to use more nitrogen fertilizers to achieve the desired yield.

Research has shown that reduced tillage can help retain up to 63% more nitrogen in the soil compared to conventional tillage.
