describe convection. how does this work to create plate boundaries?

Answers

Answer 1

Convection is the process of heat transfer within a fluid (such as air, water, or molten rock) due to the movement of the fluid itself. It occurs when warmer, less dense material rises, and cooler, denser material sinks, creating a continuous circulation of the fluid and thus transferring heat.

In the context of plate boundaries, convection works as follows:

1. The Earth's mantle is a semi-solid layer composed of molten rock (called magma) that is hotter and less dense near the core, and cooler and denser near the crust.

2. As the magma near the core heats up, it becomes less dense and rises towards the Earth's crust.

3. Once the rising magma reaches the cooler, denser part of the mantle, it transfers its heat to the surrounding material and starts to cool down.

4. As the magma cools, it becomes denser and sinks back towards the Earth's core.

5. This continuous circulation of magma creates convection currents that drive the movement of the Earth's tectonic plates.

6. The movement of these plates is responsible for the formation of plate boundaries, including divergent boundaries (where plates move apart), convergent boundaries (where plates move towards each other), and transform boundaries (where plates slide past each other).

So, convection plays a crucial role in creating plate boundaries by driving the movement of tectonic plates through the continuous circulation of magma in the Earth's mantle.

Explanation:

how do rates of erosion vary with load?

Answers

The way that the rate of erosion would vary with load is that lower load would lead to more erosion and a higher load would lead to less erosion.

What is erosion load?

The erosion load refers to the amount of eroded material that is present in water that is moving. For instance, how much sand is in the water that is flowing downhill.

The erosion load and the rate of erosion will have a negative relationship. What this means is that when the erosion load is more, the rate of erosion is less and when the erosion load is less, the rate of erosion is more.

The reason for this has to do with concentration. In cases where the erosion load is already high, the water cannot take much more sand because it is already concentrated. So there will be less erosion. The opposite is the case in the case when the erosion load is low.

Answers

Answer:

Temperature

Explanation:

The layers of the atmosphere are divided based on temperature differences.

Temperature is the degree of hotness or coldness of a body. Most of the temperature changes and differences originates from the radiated heat from the sun.

Atmosphere is the gaseous envelope round the earth.

   These layers and their temperatures are;

Troposphere                           17°C to -51°CStratosphere                          -51°C to -15°CMesosphere                            about -15°CThermosphere                         -120°C    Exsophere                                about 1500°C

The rock layer closest to the surface is ____ in age than the layers beneath them. ​

Answers

The rock layer closest to the surface is younger in age than the layers beneath them.

This is the law of superposition, which states that in a sequence of undisturbed sedimentary rocks, the oldest layers are at the bottom and the youngest layers are at the top. As a result, a geologist can tell the relative ages of the rocks based on their position in the sequence of rock layers.

The rock layers closest to the surface have been exposed to erosion and weathering, which can wear away the younger layers and leave the older ones intact. As a result, the rock layers closest to the surface are usually younger than the layers beneath them. This is because the older layers are deeper in the ground, protected by the younger layers from the effects of weathering and erosion. Therefore, the law of superposition can be used by geologists to interpret the age of the rock layers in a given area.

The two major types of dripstone are ________
which hang from cavern ceilings and _______ on the floor of caverns.

Answers

Stalactites hang from cavern ceilings, while stalagmites form on the floor of caverns.

The two major types of dripstone are stalactites, which hang from cavern ceilings, and stalagmites, which form on the floor of caverns. Stalactites are formed when water containing dissolved minerals drips from the ceiling of a cave. As the water droplets evaporate, they leave behind deposits of minerals, typically calcium carbonate, which gradually build up over time and create elongated formations hanging from the cave ceiling. Stalagmites, on the other hand, form when the mineral-rich water drips onto the cave floor and accumulates to create upward-growing formations.

Stalactites and stalagmites often occur together in cave systems, with stalactites hanging from above and stalagmites rising from the ground. These formations are a result of the slow deposition of minerals over thousands or even millions of years, and they are a fascinating feature of underground caverns.

Answers

Three of the following sources of salt in the oceans:

erosion of land areas by rivers and glaciersdecayed material from animalsprecipitation from clouds

Thus, options 'B', 'C' and 'F' are the correct options.

What are the sources of salt in the oceans?

The main sources of ocean salt are seabed openings and rocks on land. Runoff from the land and openings in the seafloor are the two sources of salt in the ocean. The main source of salts dissolved in saltwater is rocks on land. Due to its moderate acidity, rainwater that falls on land erodes rocks.

This causes ions to be released, which are then transported away by streams and rivers and finally into the ocean. The ocean's living things utilize a large portion of the dissolved ions, which are then evacuated from the water. Others are left behind, and as a result, their concentrations grow over time.

Which process removes excess water from sediment and can reduce the volume of the sediment by 40%?.

Answers

Dewatering is the process that removes excess water from sediment and can reduce its volume by 40%.

Dewatering is the process of removing extra water from sediment, which can lower the volume of the sediment by 40%. Dewatering is frequently used to remove water from saturated or water logged sediment or soil in the construction, mining and other industries.

To separate and extract the water content, it uses a variety of techniques like pumping, draining or applying mechanical pressure to the sediment. Dewatering can significantly reduce the volume of the sediment and increase its stability making it more suitable for construction or other uses.

how many major convection cells are there south of the equator

Answers

There are three major convection cells south of the equator: the Hadley cell, the Ferrel cell, and the Polar cell.

The Hadley cell, the biggest and most significant convection cell, can be found in both the northern and southern hemispheres close to the equator. Whereas the Hadley cell is towards the poles, the Ferrel cell is situated in the mid-latitudes, between the Hadley and Polar cells.

These convection cells play a crucial part in determining the temperature and weather patterns of the regions in which they are found. They are significant elements of the Earth's atmospheric circulation. For instance, the Hadley cell is in charge of creating the Intertropical Convergence Zone (ITCZ) and the trade winds, whilst the Ferrel cell is in charge of creating the westerlies and the Polar cell is in charge of creating the polar easterlies.
