Answer:
Ordovician extinction
.
Explanation:
The Ordovician extinction was an event that occurred around 450 million years ago and caused the <u>disappearance of 60% of marine species.</u>
This event was caused by global cooling which resulted in the <u>drop of the sea level</u>. This change mostly affected the species that developed life in the deep, depriving them of their natural habitat.
Equatorial regions are the regions located on or near the equator. Equatorial regions have hot and wet climate. The Amazon Basin (South America), the Congo Basin (Africa) and some regions of Asia are located in equatorial regions.
Answer:
Answer is option C (protoplanets).
Explanation:
During the formation of the solar system, a giant cloud of molecular dust collapsed to form stars, which were surrounded by a cloud of gas. The dust and other particles inside the cloud collide and merge together into larger mass through the gravitational and other forces. They continue to grow and become large enough to gravitationally attract other small celestial objects to form protoplanets. Some of the protoplanets continue their growth through the process called accretion and form planets.
Planetesimals - The small celestial objects formed during the early stages of the creation of the solar system.
Protoplanets - The objects formed when planetesimals became large enough to attract their neighboring celestial bodies through the force of gravity and grow by the process known as accretion, where they collide and merge together into larger bodies.
Extrasolar planets - The planets found outside our solar system (orbit another star, not the Sun).
Erosion over time. They would fit roughly together, But not perfectly due to the Years and Years of Erosion.
