What are the blotches on the Sun's surface that appear darker than surrounding regions?
The blotches on the Sun's surface that appear darker than surrounding regions are called sunspots. They are temporary phenomena caused by intense magnetic activity, which inhibits convection and reduces surface temperature. Sunspots are often associated with solar flares and coronal mass ejections.
Which star has the highest surface temperature?
The star with the highest surface temperature is the blue star called O-type stars. These stars can have surface temperatures exceeding 50,000 degrees Celsius.
What is an area on the sun cooler than any other area on the sun called?
A cool, dark area on the sun's surface is called a sunspot. Sunspots are areas of reduced temperature that appear dark against the brighter background of the surrounding solar surface because they are regions of concentrated magnetic field flux inhibiting convective flow.
Dark marks on the sun?
Dark marks on the sun are known as sunspots. They are areas of cooler temperature on the sun's surface caused by strong magnetic activity. Sunspots can vary in size and shape and play a role in the sun's 11-year solar cycle.
What is the small sunspot called?
A small sunspot is called a plage. Plages are regions on the Sun's surface that appear brighter than their surroundings due to intense magnetic activity.
What is the ocean surface temperature called?
temperature
What are melting regions in the mantle called?
Melting regions in the mantle are called melting anomalies or melting zones. These are areas where the temperature and pressure conditions are conducive for the partial melting of mantle rocks, leading to the formation of magma that can eventually erupt at the surface as lava.
When regions of earth's surface sinks down what is it called?
Subsidence.

When earths regions of earths surface sinks down what is it called?
Subsidence.
What are physically homogeneous regions called?
Physically homogeneous regions are called isotropic regions. This means that the physical properties, such as temperature or density, are uniform in all directions within the region.
What are flat regions of dry lava on the surface of the moon called?
Flat regions of dry lava on the surface of the moon are called maria. They are large dark basins formed by ancient volcanic activity and are visible from Earth as dark areas on the lunar surface.
What is is a large section of the lower troposphere with uniform temperature and humidity is called what?
A large section of the lower troposphere with uniform temperature and humidity is called an air mass. Air masses are large bodies of air with relatively homogeneous properties that form over specific regions of the Earth's surface.
What is a representation usually on a plane surface showing region of the earth?
A representation on a plane surface showing regions of the Earth is called a 'projection'. Or it might simply be called a map.
Regions on the equator where surface winds are very calm are called what?
This area is called the Doldrums. Horse Latitudes are farther north.
An unnatural temperature increase in the atmosphere near Earth's surface is called .?
Global warming
What is moving surface water called?
Moving surface water is called a current. This movement is often driven by factors such as wind, temperature, and the Earth's rotation.
