Answer:
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.
Explanation:
The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.
Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.
Answer:
B it reflects light from the sun.
Explanation:
the moon doesnt give off its own light, it reflects the light of the sun that hits it.
please mark brainliest im trying to level up :)
Answer:
Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.
Composite volcanoes are tall, steep cones that produce explosive eruptions.
Shield volcanoes form very large, gently sloped mounds from effusive eruptions.
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.
Explanation:
Answer:
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.

Archaeopteryx had "teeth, three claws on each wing" similar to dinosaurs. So, most appropriate answer would be Teeth & Wings
Hope this helps!
