Answer: a) chunks of the core of a larger asteroid that was shattered by a collision.
Explanation:
The processes meteorites are the large celestial objects that are formed by the collision of large planatery bodies or asteriods. These consists of crust, mantle and core similar to that of the terrestrial planets. These can be define as the fragments of asteroids who have melted interiors in which the heavier metals sank inside the center and the lighter rocks raise to the outer surface. This process of formation of processed meteorites is called as differentiation.
Answer:
<em>The air particles in the thermosphere absorb high-energy radiation from the Sun.</em>
Explanation:
The thermosphere lies above the mesosphere but below the exosphere in the Earth's atmosphere. The thermosphere can be considered to be part of space because of how close to space it lies, and ionization of particles by ultraviolet rays occurs a lot here; this been that some part of the thermosphere is overlapped by the ionosphere. Due to its proximity to space, particles in the thermosphere are exposed to a high level of solar energy radiation, which causes their temperature to be very high, sometimes as high as 1700 °C or more.
