4. The word ” accordingly” in the passage is closet in meaning to
5. Which of the following can be inferred from paragraph 3 about meteorites?
- Their composition can help determine the part of the larger body from which they broke off.
- They are difficult to distinguish from rocks in Earth’s mantle.
- Their collisions with Earth have become more frequent than in the past.
- They are older than the rest of the solar system.
Some meteorites consist of rocky material and, accordingly, are called stony meteorites. Others are metallic and have been designated iron meteorites even though they contain lesser amounts of elements other than iron. Still others consist of mixtures of rocky and metallic material and thus are called stony-iron meteorites. Meteors come in all sizes, from small particles to the small planets known as asteroids; no asteroid, however, has struck Earth during recorded human history. Many meteorites appear to be fragments of larger bodies that have undergone collisions and broken into pieces. Iron meteorites are fragments of the interiors of these bodies, comparable to Earth’s core, and stony meteorites are from outer portions of these bodies, comparable to Earth’s mantle (the layer between the core and outer crust).
