Drowned river valleys are known in Tennessee California US states.

Due to either down warping along the shoreline or eustatic sea-level rise, rivers that flow into a sea or lake may drown or fill with sea water.

Former river valleys frequently display a dendritic network of tributary valleys and transform into deeply indented bays and estuaries.

Drowned river valleys are distinguished by the extension into an existing river system landward, river valley cross sections, shallow waters in the estuary, and corresponding bottom levels.

Estuaries of drowned river valleys are created when existing river valleys are flooded by rising sea levels.

The Chesapeake and Delaware Bays on the Atlantic coast are the largest drowned valley coasts in the United States.

Thus, Drowned river valleys are known in Tennessee California US states.

Frost wedging is an important, mechanical weathering process for enlarging fractures and extending them deeper into large boulders and bedrock.

The Frost wedging process takes place in extremely cold regions. Water filling expands when ice exerts a great amount of force on the rocks.

It is a physical disintegration weathering procedure during which ice imparts a force on the rock and results in enlarged fractures and wedges in rocks.

The term 'frost wedging' is a combined term for the mechanical weathering process during which water freezes into ice and expands  8 to 11% in its volume and resultantly putting pressure on the rocks.

In general, frost wedding is an umbrella term that covers a wide variety of processes such as cryofracturing,  frost shattering, and wedging that collectively cause rock deformation overtime.

Answer:

Let (x,y) be unknown endpoint.

Midpoint formula is given as [(x1+x2)÷2, (y1+y2)÷2]

[x+(-10)÷2, (y+4)÷2] = (-6,-4)

Compare the x coordinates and y coordinates of midpoint and endpoint.

(x-10)÷2 = -6 (y+4)÷2 = -4

x-10 = -6(2) y+4 = -4(2)

x-10 = -12 y+4 = -8

x = -2 y = -12

Hence, coordinates of endpoint is (-2, -12).

1. Sea floor spreading is the cause of the gradually expanding distance between South America and Africa.

The idea of a moving seafloor and how it carries the continents with it was first proposed in 1960 by Harold Hammond Hess of Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory. This phenomenon is known as plate tectonics. At the mid ocean ridges, where it occurs, plates separate, causing seafloor spreading, which leads to the production of new sea floor.

2. A hotspot provides the energy for Old Faithful Geyser in Yellowstone National Park in the United States.

All of Yellowstone's well-known geysers are powered by a sizable subterranean hotspot, according to researchers. Hot molten rock is present beneath the Yellowstone.

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.

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.

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.

In meteorology, precipitation is any product of atmospheric water vapor condensation that falls under the gravitational pull of clouds.

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.
