The earth is round because its interior rock is warm enough to flow slowly in response to gravity.
The processes involved in the gradual but ongoing transformation of the rock constituents of the crust from one shape to another are outlined in the rock cycle. The hydrological cycle, which refers to the flow of water, ice, and air at the surface and is powered by the sun, and the internal heat engine of the Earth, which shifts material across the core and the mantle and causes gradual but major changes within the crust, are the two forces that drive the rock cycle.
On Earth, the rock cycle is still in motion because our atmosphere is quite thick, our core is heated enough to continue the mantle flowing, and we have liquid water.

Convection in the mantle causes hotter material to rise and cooler material to sink down.
Option C is correct.
Which heat causes convection in the mantle?For mantle convection, there are three primary sources of thermal energy: internal warming brought on by the radioactive decay of the uranium, thorium, and potassium isotopes; the earth's long-term secular cooling; as well as core heat.
What exactly is convection and how does it work?Convection occurs when parts of a liquid or gas heat or cool faster than their surroundings, resulting in temperature differences. The areas then move as a result of these temperature differences, with the hotter, denser areas rising and the cooler, denser areas sinking.

On the two equinoxes, each region received around 12 hours of daylight.
Given a level horizon and no air refraction during the day of the celestial equator, the sun's center would set roughly 12 hours after rising.
The vernal equinox, which occurs in the spring around March 21, as well as the autumn equinox, which occurs in the fall around September 23, are the days when the earth receives 12 minutes of sunlight and 12 hours of darkness.
Locations near the equator receive just approximately 12 hours of light every day.

based on principles discussed earlier in the course, you know that as distance from the equator increases, seasonal variation in temperature tends to .
As distance from the equator increases, seasonal variation in temperature tends to decrease.
A place's climate is influenced by how far it is located from the equator. In comparison to the equator, solar radiation has to travel further and at a shallower angle to reach the surface of the Earth at the poles, where the atmosphere is more dense. Because of this, the climate becomes increasingly colder as one moves away from the Equator.
In the summer, there is a period of time at the poles when the sun does not set, and in the winter, there is a period of time at the poles when it is completely dark. This is the greatest variation in day length that occurs between the summer and the winter at the poles. On the other hand, day length varies very little near the equator.

Describe how echo soundings are used to determine the topography of the ocean floor?
The time it takes for the echoes to return to the point of origination is then used to determine the depth and corresponding shape of the ocean floor.
An echo sounder transmits a ship's sound signal into the water, where it bounces off any changes in density to produce echoes (e.g., the seafloor). The time it takes for the echoes to return to the point of genesis is then used to calculate the depth and corresponding shape of the ocean floor.
What do we mean by an echo?An echo is a sound produced when sound waves are reflected off of a surface and returned to the listener.
It is the sound that has been reflected, and it reaches the listener after the original sound has passed.
Your throat is opened, and a flexible tube with a transducer is inserted into the tube that connects your mouth and stomach (esophagus).
The transducer captures the echo of your heartbeat on tape.
The echoes are transformed by a computer into exact moving pictures of your heart that your doctor may see on a monitor.
A ship's sound signal is sent down into the ocean using an echo sounder, where it bounces off any differences in density to create echoes (e.g., the seafloor).
The depth and the associated shape of the ocean floor are then calculated using the time it takes for the echoes to return to the point of genesis.
Therefore, an echo sounder transmits a ship's sound signal into the water, where it bounces off any changes in density to produce echoes (e.g., the seafloor).

The line of demarcation would ultimately decide where Portuguese would be spoken in South America and where Spanish would be spoken.
What is the line of demarcation and how did it came between spanish and portugues?
The Line of Demarcation was a line established in 1494 by the Treaty of Tordesillas between the Kingdoms of Spain and Portugal. It was meant to divide the New World territories between the two countries. The Line of Demarcation ran along a meridian 370 leagues (1770 km) west of the Cape Verde Islands, which were off the west coast of Africa. All newly discovered lands to the west of the line belonged to Portugal, while any found to the east belonged to Spain. The line was intended to settle a dispute between the two nations and was a major factor in the global expansion of European colonialism in the 16th century. It had lasting effects on the geopolitical balance of power in the New World and the Old World.
What does geopolitical means?
Geopolitics is the study of the effects of geography (physical and human) on international politics and international relations. It involves the analysis of political power in relation to geographic space. It is often seen as an important factor in shaping foreign policy and international relations. The term "geopolitics" was originally coined by the Swedish political scientist Rudolf Kjellén in 1899. It has come to refer to the study of the role of geography in shaping and influencing the behavior of states, as well as the political and economic strategies they employ.

Minerals present, crystal/clast size, crystal/clast shape, and presence/absence of layers are evaluated to classify crystalline and clastic rocks.
Texture, or the size, shape, and arrangement of the constituent minerals, is a prominent physical feature of terrigenous clastic rocks. There are three major types of sedimentary rocks: terrigenous clastic sedimentary rocks, carbonates, and noncarbonate chemical sedimentary rocks.
A crystalline rock is one that is entirely composed of crystallized minerals and contains no glassy matter. Intrusive igneous rocks are always crystalline, especially when they cool to semi-solidity at depth, whereas extrusive igneous rocks are mostly non-crystalline because they can be partially or completely glassy. Clastic rocks are made up of pre-existing mineral and rock fragments, or clasts. A clast is a fragment of geological detritus, chunks, or smaller grains of rock that have been physically weathered off other rocks.

The Enhanced Fujita scale (EF-scale) is a method for categorizing tornado strength based on the amount of damage they produce. The scale goes from EF0 to EF5, with EF0 being the weakest and EF5 being the strongest.
The least powerful tornadoes, or EF0s, have winds of 65 to 85 mph and only moderate damage to buildings, such as shingle and siding damage. With wind speeds ranging from 86 to 110 mph, EF1 tornadoes can cause only moderate harm to trees and buildings, including uprooted trees and overturned single wides (trailers). Wind speeds from EF2 tornadoes range from 111 to 135 mph, and they can seriously harm homes, mostly destroying the walls and roofs. Wind speeds from EF3 tornadoes range from 136 to 165 mph and can destroy large portions of school buildings in addition to causing severe damage to homes and buildings. With wind speeds ranging from 166 to 200 mph, an EF4 tornado can destroy everything in its path, leaving only foundations or rubble.

which of the following best describes a benefit of increasing the number of offshore wind farms rather than onshore wind farms?
Answer:
One benefit of increasing the number of offshore wind farms rather than onshore wind farms is that offshore wind tends to be more consistent and stronger. The wind is stronger and more consistent over the ocean than it is over land, so offshore wind farms can typically generate more electricity than onshore wind farms. This is because wind speeds are generally higher and more consistent over the ocean than they are over land, so offshore wind turbines can operate at higher capacity factors, which results in more energy generation per turbine.
