Coral reefs are a very important component of the ocean’s ecosystem because they support sea life, such as crabs and sea turtles. in fact, over four thousand species depend on the survival of the reefs, which are being destroyed by bleaching. more must be done immediately to save the reefs.
development along the coastal regions has significant negative effects on coral reefs. the reefs are an essential part of the ocean’s ecosystem, and when people build structures on top of them, they are easily damaged because they are so fragile.
Roughly 7! 7 x 48 is 336 which is two short so maybe just say 8 to be safe.
During Hadean time, the solar system was forming within a cloud of dust and gas known as the solar nebula, which eventually spawned asteroids, comets, moons and planets. Astrogeophysicists theorize that about 4.52 billion years ago the proto-Earth collided with a Mars-size planetoid named Theia.
i hope this helps you
from google:
"The Earth gets hotter as one travels towards the core, known as the geothermal gradient. Geothermal gradient is the amount the Earth's temperature increases with depth, indicating heat flowing from the Earth's warm interior to its surface. On average, the temperature increases by about 25°C for every kilometer of depth"
