Explanation:
the sea was formed by the enlargement of a river valley that was scoured by glaciers and then filled in by the sea. the sea was isolated from a larger sea, was reduced in size, and was flooded during sea-level rise.
The baltic sea was formed by the enlargement of a river valley that was scoured by glaciers and then filled in by the sea. The black sea was isolated from a larger sea, was reduced in size, and was flooded during sea-level rise.
The baltic sea is an expanded piece of shallow sea and part of the Atlantic sea and was formed as a result of the combination of large waterways and rivers that was later filled in by the sea.
It is attached to the white sea through artificial waterways and is stretched between 10°E - 30°E longitude and 53°N - 66°N latitude. Moreover, the sea is enclosed by Russia, Germany, Sweden, and Denmark.
On the other hand, about 10,000 years ago, the black sea was a freshwater lake.
However, according to marine geologists, it emerged about 7000 years ago as a result of structural upheavals in the Atlantic Ocean. It is also called the Mediterranean sea.

The introduction of free oxygen to Earth's atmosphere occurred approximately 2.4 billion years ago and is called the Great Oxygenation Event, or GOE. A second such event began about 700 million years ago.
In history, the Great Oxygenation Event began when cyanobacteria managed to carry out the process of photosynthesis and produce oxygen as a by-product approximately 2.4 billion years ago.
As the oxygen concentration began to rise, the anaerobic population of bacteria began to decline. This was the biggest mass extinction that occurred first on Earth.
The production of oxygen led to other life forms coming into existence. All these aerobic life forms came into existence when the concentration of oxygen began to rise on Earth.

The correct answer is option A: air spirals out of the high in a clockwise direction.
In the northern hemisphere, the airflow is clockwise direction around areas of high pressure.
The movement of the earth around its axis is responsible for the change in the direction of air in the Northern and Southern hemispheres.
However, there is another effect that changes air direction called 'The Coriolis effect.
In the Northern hemisphere, the Coriolis effect diverts the air directly to the right side of the hemisphere making airflow parallel to the isobars.
In general, around high-pressure regions, the direction of airflow is clockwise, and around low-pressure areas, the direction of airflow is counterclockwise.

in which ways is the carbon in limestone released back into the atmosphere? i. plants leach out the carbon in limestone and consequently release co2 after they are decomposed. ii. geologic processes bring the sediments to the surface, where they are attacked by o2 iii. acid rain dissolves limestone.
The correct answer is option ii.
The carbon in limestone is released back into the atmosphere through the geologic processes bringing the sediments to the surface, where they are attacked by O2.
In geology, the carbon cycle is a process through which carbon dioxide is repeatedly exchanged between the atmosphere, living organisms, and the hydrosphere to keep its levels sustained and balanced.
Carbon is an essential constituent of nature and is present in living organisms, matter, oceans, and the atmosphere in the form of carbon dioxide.
Furthermore, it is also stored in sediments and rocks under immense temperature and pressure also termed carbon sinks.
Geological processes such as weathering and precipitation decompose the organic matter or sedimentary rocks e.g. limestone as a result of which carbon dioxide is sent back to the atmosphere.
In general, carbon dioxide dissolves in oceans, and ocean water ventilates carbon dioxide back to air.

In meteorology, precipitation is any product of atmospheric water vapor condensation that falls under the gravitational pull of clouds.
What is precipitation ?Drizzle, rain, sleet, snow, ice pellets, graupel, and hail are the most common types of precipitation. When a portion of the atmosphere becomes saturated with water vapor (reaches 100% relative humidity), the water condenses and "precipitates" or falls.
Because the water vapor does not condense sufficiently to precipitate, fog and mist are colloids rather than precipitation. Two processes, possibly acting in tandem, can cause air to become saturated.

Earthquake-related tsunamis are created by subsea fault movements with pronounced vertical offsets of the seafloor. such movements occur most commonly along the subduction zones.
The region where two tectonic plates collide with each other on the earth's surface is called a subduction zone.
In this geological process, the heavy oceanic plate or lithospheric plate moves down into the mantle where it is recycled through melting under high temperatures and pressure.
In general, at convergent boundaries, when a highly dense lithospheric plate converges with a less dense lithospheric plate then the heavy plate slides beneath the lighter plate into the mantle resulting in the formation of volcanoes.
Subduction zones are responsible for devastating tsunamis, earthquakes, and landslides and volcanic ranges are also formed along convergent edges.

Relative dating ______ to determine the order in which geologic events occurred.
Relative dating uses geologic principles to determine the order in which geologic events occurred.
Without necessarily determining their absolute ages, relative dating is the science of figuring out the relative sequence of historical events (i.e., the age of an object in comparison to another) (i.e., estimated age). In geology, one stratigraphic column can be correlated with another using rock or surface deposits, fossils, and lithologies.
Prior to the early 20th century discovery of radiometric dating, which offered an absolute dating method, archaeologists and geologists utilized relative dating to ascertain the ages of materials.
Relative dating is nevertheless a helpful technique even though it can only tell you the order in which a set of events happened, not when they did. In certain ways, relative dating via biostratigraphy is more accurate and is the method of choice in paleontology.
