B. Kuiper belt
the gravitational collapse of a cloud of cosmic dust and gases
Which process is happening at places where the plates that form the sea floor border each other?(1 point) Responses The plates spread, bringing up new material from deep in Earth. The plates spread, bringing up new material from deep in Earth. One plate will go under the other, causing a slow rise of the top plate. One plate will go under the other, causing a slow rise of the top plate. The plates collide, sending matter from both plates deep into Earth. The plates collide, sending matter from both plates deep into Earth. One plate will go under the other, causing a slow horizontal shift as the top plate moves.
One plate will go under the other, causing a slow rise of the top plate.
Which statements are true of meteorites? Select the two correct answers.(1 point) Responses Inclusions in meteorites are the oldest material ever dated. Inclusions in meteorites are the oldest material ever dated. The composition of meteorites reflects the composition of the cosmic material from which planets formed. The composition of meteorites reflects the composition of the cosmic material from which planets formed. The impact craters from meteorites help determine the ages of the gaseous planets. The impact craters from meteorites help determine the ages of the gaseous planets. Planets were formed by the accretion of meteorites.
Inclusions in meteorites are the oldest material ever dated.
The composition of meteorites reflects the composition of the cosmic material from which planets formed.
Which statements are true of radiometric dating of rocks? Select the two correct answers.(1 point) Responses This technique has led scientists to rely on fossils to determine the age of Earth. This technique has led scientists to rely on fossils to determine the age of Earth. Radiometric dating of meteorites has led scientists to believe that the solar system formed about 4.5 billion years ago. Radiometric dating of meteorites has led scientists to believe that the solar system formed about 4.5 billion years ago. This technique suggests that most of Earth's crust is not as old as material from meteorites. This technique suggests that most of Earth's crust is not as old as material from meteorites. Radiometric dating of rock suggests that Earth is older than the other rocky planets.
