The large ocean that existed about 220 million years ago, forming about 60% of the earth's surface was known as Panthalassa.
Panthalassa was a superocean that surrounded the supercontinent Pangaea. It was the largest single ocean in the history of the earth, covering nearly two-thirds of the planet's surface.
Panthalassa also extended beyond the present-day Pacific, covering large areas of the Indian, Arctic, and Atlantic oceans, including most of the southern hemisphere.The term Panthalassa means "all seas" in Greek, and the ocean was so named because it covered most of the earth's surface.
Although Panthalassa no longer exists as a single ocean, it can be viewed as a precursor to today's Pacific Ocean, which is still the largest body of water on earth.
The splitting of Pangaea into smaller landmasses and the movement of tectonic plates have changed the earth's surface and reduced the size of the oceans, leading to the creation of new bodies of water, such as the Atlantic and Indian oceans.

About 2.0 billion years ago, complex organisms began to inhabit Earth. These complex organisms developed primarily because of —changes in atmosphere gases
sunlight being absorbed by land
the eruption of volcanoes
the impact of comets
Volcanic activity created the _____ that is important to the economy of the village of Vestmannaeyjar on the island of Heimaey, near Iceland.
fishing port
volcanic peaks
mineral ores
hot springs
Volcanic activity created the fishing port that is important to the economy of the village of Vestmannaeyjar on the island of Heimaey, near Iceland. Hence, option A is correct.
When the magma chamber becomes sufficiently overfilled, the magma forces its way to the surface and erupts, frequently resulting in volcanic eruptions. Volcanoes in the ocean erupt along fissures in the ocean floor caused by the spreading of two plates known as a mid-ocean ridge.
A port or harbor used for the distribution of fish is known as a fishing port. It could be a place for relaxation, but it's mainly for business. The only port that is dependent on an ocean commodity is a fishing port, therefore a fishing port may become unprofitable if fish stocks decline.
Iceland's location along the Mid-Atlantic Ridge in the North Atlantic Ocean, wherein the Eurasian and North American plates are separating by a few centimeters per year, is thought to be the cause of the country's volcanic activity. This sudden eruption of volcanic activities resulted in a fishing port, which is quite economical for the people of Vestmannaeyjar on the island of Heimaey, near Iceland.

explain how the thermohaline circulation (thc) works and how temperature and salinity changes; near the ocean surface and in the ocean depths. how does evaporation change ocean salinity?
Thermohaline circulation (THC) is the global ocean circulation pattern driven by temperature and salinity differences. Near the ocean surface, the temperature of the ocean is determined by air-sea interactions. The salinity near the ocean surface is determined by the amount of evaporation from the ocean and the amount of precipitation that falls into the ocean.
As the ocean water gets deeper, the temperature and salinity become more constant. In the depths of the ocean, salinity is determined by the amount of dissolved salts that have been slowly sinking from the upper layers of the ocean. Evaporation from the ocean surface removes fresh water from the surface and leaves the saltier water behind, making the ocean surface water more saline. Precipitation, however, adds fresh water to the ocean and thus decreases the salinity of the ocean.

Why are there high mountain systems in the south of Europe?
The high mountain systems in the south of Europe, such as the Alps, Pyrenees, and Apennines, are the result of tectonic activity and plate movements that occurred millions of years ago.
During the Mesozoic Era, which spanned from about 252 to 66 million years ago, the African plate began to move northward, eventually colliding with the Eurasian plate. This collision caused the crust to buckle and fold, resulting in the formation of the Alpine mountain range, which stretches from France to Slovenia.
Similarly, the Pyrenees mountain range, which runs along the border between France and Spain, was formed by the collision of the Iberian plate and the Eurasian plate around 50 million years ago.
The Apennine Mountains in Italy are also the result of tectonic activity, specifically the convergence of the African and Eurasian plates.
In summary, the high mountain systems in the south of Europe are the result of complex tectonic processes that occurred over millions of years.

When comparing and contrasting the collaborative work between Antoni and Petronio with Gustav Klimt's painting, we can observe distinct differences in their views of death. The collaborative work between Antoni and Petronio showcases death as a natural process of decay and transformation, emphasizing the idea of change and renewal. In contrast, Gustav Klimt's paintings present death as a looming, omnipresent force, underlining the vulnerability and impermanence of life.
Antoni and Petronio's collaboration is characterized by a focus on the process of decay and transformation. Their work, such as their project "Arte Morte," utilizes materials like animal carcasses and insects to represent the natural cycle of life and death. In this way, their work portrays death as a necessary and inevitable part of existence, emphasizing the idea of constant change and renewal.
On the other hand, Gustav Klimt's paintings, like "Death and Life," provide a more symbolic and metaphorical view of death. Klimt often personifies death as a skeletal figure draped in a cloak, hovering over the living. His work conveys the idea of death as an omnipresent force that is always lurking in the background, waiting to claim its next victim.

you see in the southern Ontario landscape. Where did these features come from?
*NO LINKS ALLOWED! ANY ANSWER WITH LINKS RESULTS INTO A REPORT.* Brainliest will be given to the first person to answer effectively.
Answer:
Explanation:
Glaciation played a significant role in the formation of the hills and valleys seen in southern Ontario's landscape. During the last ice age, which lasted from about 110,000 to 12,000 years ago, much of North America was covered by a massive ice sheet called the Laurentide Ice Sheet. This ice sheet was responsible for carving out many of the valleys and hills in southern Ontario.
As the ice sheet advanced and retreated, it ground the underlying rock and soil, creating deep grooves and channels. As the ice sheet melted, the water carried away the loose material, leaving behind valleys and depressions. The retreat of the ice sheet also left behind moraines, which are ridges of glacial debris that were deposited along the ice sheet's edge.
In addition to the physical erosion caused by the ice sheet, glaciation also had an impact on the region's hydrology. The melting of the ice sheet created vast amounts of meltwater, which carved new river channels and contributed to the formation of the many lakes and wetlands in the region.
Overall, the combination of physical erosion and changes in hydrology caused by glaciation played a significant role in shaping the hills and valleys of southern Ontario's landscape. These features serve as a reminder of the powerful and transformative effects of glaciation on the region's geology and ecology

What conditions are necessary for the formation of thunderstorms? A. High humidity, lifting force, and unstable conditions. B. High humidity, high temperature, and cumulus clouds. C. Lifting force, moist air, and extensive cloud cover.
The conditions necessary for the formation of thunderstorms are High humidity, lifting force, and unstable conditions. The correct option is "A".
The formation of thunderstorms is dependent on three key conditions: high humidity, lifting force, and unstable conditions. High humidity is necessary to provide moisture in the atmosphere which can then be released as rain. A lifting force, such as warm air rising, is needed to move the moist air upward and cause it to condense and form a cloud.
Lastly, the atmosphere needs to be in an unstable state for a thunderstorm to occur, meaning it must be conducive to vertical air currents. Without all three of these conditions present, a thunderstorm cannot form.

according to the map, higher levels of primary production occur in coastal waters compared to the open ocean. what is the best explanation for this observation?
The best explanation for this observation is that coastal waters receive more nutrients from land-based sources.
Coastal regions often receive a greater input of nutrients from rivers, runoff, and other terrestrial sources than the open ocean. These nutrients can include nitrogen and phosphorus, which are essential for the growth of phytoplankton, the primary producers in marine ecosystems. In addition, coastal waters tend to be shallower and more sheltered than the open ocean, which can promote the growth of phytoplankton. Shallow waters receive more sunlight, which can fuel photosynthesis and support the growth of phytoplankton. The sheltered conditions in coastal waters can also help to retain nutrients, further supporting the growth of phytoplankton.
Human activities can also play a role in increasing nutrient levels in coastal waters. Agricultural runoff, sewage discharge, and other forms of pollution can increase nutrient levels in coastal waters, leading to eutrophication, or an overgrowth of phytoplankton. This can have negative impacts on marine ecosystems, including the formation of harmful algal blooms and oxygen depletion in the water.

St. Helens eruption in Washington state in 1980 measured 5 on the volcanic explosivity index MEI. Only 57 people died from the Mt. St. Helens since most people were warned to evacuate the area prior to the event Four years later, in 1985, Nevado del Ruiz in Colombia erupted. While only measuring 3 on the VEl, the eruption resulted in 25.000 deaths when unsuspecting residents of local towns were overrun by fast-moving lahars. Which of the following statements about volcano-related deaths best fit the information given in the paragraph? Volcanic eruptions often kill thousands of people. The death toll from volcanic eruptions do not always correlate to explosivity, and can be affected by human actions before and after the eruption. Most volcano-related deaths occur from lahars. The death toll from a volcanic eruption is directly related to its volcanic explosivity index (VEI)
The statements about volcano-related deaths that best fit the information given in the paragraph is death toll from volcanic eruptions do not always correlate to explosivity, and can be affected by human actions before and after the eruption. The Option B is correct.
How do we describe the volcano-related deaths?The paragraph provides two examples of volcanic eruptions with different volcanic explosivity indices (VEI), but vastly different death tolls. The Mt. St. Helens eruption had a higher VEI (5) than the Nevado del Ruiz eruption (3), yet resulted in far fewer deaths (57 vs. 25,000).
This suggests that human actions, such as timely evacuation, can greatly reduce the number of casualties from a volcanic eruption. Additionally, the paragraph notes that the lahars resulting from the Nevado del Ruiz eruption were responsible for most of the deaths, highlighting the danger of volcanic mudflows.
