200oC is the approximate maximum temperature range for the formation of metamorphic rocks.
How are metamorphic rocks formed ?
Rocks that undergo metamorphosis are created when heat and pressure transform the original or parent rock into a whole new rock. Sedimentary, igneous, or even another metamorphic rock can serve as the parent rock. The Greek root of the term "metamorphic" means "To Change Form."
At subduction zones, the descending rock strata have two effects that lead to metamorphism: first, the shearing of the plates as they pass one another changes the rocks that come into touch with the descending rocks. Because of this friction, some of the rock will melt as it descends. Rock that melts is classified as igneous rather than metamorphic, however rock close to the melting rock may undergo metamorphism due to heat.

Which diagram shows an oceanic-oceanic convergent boundary? describe what occurs at this type of plate boundary
Oceanic-oceanic convergence is shown in Diagram B. These plates generate a deep marine trench. In the ocean, parallel to the trench, volcanoes can potentially develop.
What are the convergent boundaries?
Different plates on our planet interact with one another, move past one another, and pull apart from one another. There are several diverse plate borders, breathtaking scenery, and perilous perils as a result of these motions between the plates. In general, there are three different types of plate contact. Convergent borders are the first of them, which we shall examine below.
Two or more tectonic plates can move toward one another at convergence borders. The two tectonic plates are squeezed or pushed together during the convergence process by compressional stress. Mountain chains are most frequently recognised to be formed by convergent boundaries. Earth has seen periods of supercontinent creation, during which the continents as we know them now were once combined into one landmass, as a result of tectonic plate collisions. Supercontinents used to exist more than 250 million years ago, and one well-known example is the ancient continent of Pangaea.

State a probable period of revolution of the planet
Thelma using proper units.
The period of revolution of the planet Thelma using proper units is 365 Days.
The planets' rotation is not induced by any external force. The conservation of angular momentum is primarily responsible for rotation. L=m*w*r2 is the formula for angular momentum, where m stands for mass, w for angular velocity in radians per second, and r for the circumference of the circular motion.
As the planet gets farther from the sun, the period of revolution lengthens. Neptune therefore has the longest revolution period. Seasons, aphelion, and perihelion are all effects of the revolution on earth. The apogee is the distance between the earth and the sun. The earth is closest to the sun at perihelion.

True ,seawalls are constructed perpendicular to the shore to prevent wave erosion.
What is wave erosion ?
Waves may erode beaches on a variety of geographical and temporal dimensions. A scour zone moves up the beach or down the beach with every rise and fall in the tide. At the tide level, there is a turbulence zone where suspension of sediment is common. It is also the zone where the backwash meets the oncoming surge.
The erosion occurs between three percent and forty percent of the breaker height and deeper. As the tides vary, the breaker zone likewise moves down the beach. Sediment migration in the foreshore-inshore region is highest within the breaking zone. In actuality, the breaker zone is where nearly 50% of the sediment flow occurs.

when levels of certain aerosols increase or ash from large volcanic eruptions stays in the atmosphere for extended periods of time, some solar energy can be blocked from reaching earth's surface and can cause average global temperatures to decrease. this is a process called global cooling.
What is global cooling?
An imminent cooling of the Earth that would result in a period of severe glaciation due to the cooling effects of aerosols or orbital forcing was hypothesized, particularly during the 1970s. The scientific literature of the 1970s was largely more concerned with warming from an increasing greenhouse effect, but some journalistic reporting in that decade speculated about continued cooling.
The few temperature series that were available in the middle of the 1970s indicated that the temperature had been dropping for several decades prior to that point. It became evident that the average global temperature had significantly increased as longer time series of higher quality became available.
Scientists began to realise, by the 1970s, that estimates of world temperatures indicated cooling since 1945 as well as the potential for significant warming brought on by greenhouse gas emissions. Less than 10% of the scholarly articles that examined 21st-century climate trends tended to forecast future warming, while the majority expected future cooling. A 25% rise in atmospheric carbon dioxide over the 150 years from 1850 to 2000, together with a corresponding warming trend, was predicted by Science News in May 1959, despite the fact that the general public was mostly unaware of the effects of carbon dioxide on the climate. The actual growth during this time was 29%. Paul R. Ehrlich noted in 1968 that the cooling impact of aerosols was being countered by global warming from greenhouse gases.

what surface feature which helps cycle moisture in arizona during the north american monsoon and occurs in late summer once temperatures across the desert southwest become very hot?
A surface feature called a thermal low-pressure forms in the deserts of North America ( southeastern California )and southwest Arizona
What is thermal low pressure?
Thermal lows, also known as heat lows, are non-frontal low-pressure regions that develop over the subtropical continents in the summer season as a result of extreme warmth relative to their surrounding environments. [1] Thermal lows can be found close to the Sonoran Desert, on the Mexican plateau, in the Great Central Valley of California, over the Sahara, in north-western Argentina, in north-western Australia, over the Kimberley region of the Iberian Peninsula, and over the Tibetan plateau.
Through reradiated energy in the infrared spectrum, intense, rapid solar heating of the earth's surface heats the lowest layers of the atmosphere on land. A low-pressure area is created when hotter air rises because it is less dense than the cooler air around it. Because they warm up more quickly than the atmosphere around them at the same altitude, elevated places can strengthen the thermal low. When the air covering the land is colder than the warmer water body, instability lows develop over water during the winter.

is this statement true or false? the hydrosphere includes all liquid and frozen surface waters, groundwater held in soil and rock, and atmospheric water vapor.
This statement is TRUE.
The hydrosphere does consist of all liquid and frozen surface waters, groundwater contained in soil and rock, and air water vapor.
ABOUT THE HYDROSPHERE
The hydrosphere consists of surface water, subsurface water, and atmospheric water. The hydrosphere of a planet can consist of liquid, vapor, or ice. On Earth's surface, liquid water exists in the form of seas, lakes, and rivers. Additionally, it exists as groundwater in wells and aquifers.
The hydrosphere consists of oceans, freshwater, surface water, groundwater, glacial water, and water vapor in the atmosphere. Certain Hydrosphere facts are there are approximately 332.5 million cubic miles or 1,386 million cubic kilometers of water on Earth (km3). The Earth is considered a water planet due to the dependence of life on the hydrosphere's water. Permanent snow contains roughly 68.7 percent of all freshwater.
FURTHER INFORMATION
Once the planet's surface had sufficiently chilled, water held in the minerals of the accreted material and released at depth could escape to the surface, cool, and condense to form the original hydrosphere.
Nobody discovered the hydrosphere, as humans have always been enveloped by water. Still, Austrian geologist Edward Suess developed the term (along with numerous other spheres) in 1875 as he attempted to apply a systems approach to the various sciences of Earth's natural environment.

One distinction is how quickly terrestrial areas are warming compared to ocean places. But the Arctic is likely the biggest outlier, warming more than twice as quickly as the world average.
This process, called "Arctic amplification," is linked to extreme weather events in the northern hemisphere's mid-latitudes and is creating significant changes for Arctic communities.
The loss of snow and sea ice in the Arctic, which results in less incoming sunlight being reflected back out to space, is often cited as the reason of this rapid warming.
