NGSS Earth Science

Earth formed in a swirling disk of matter surrounding the sun. As particles in the disk collided and stuck together, they grew larger and some eventually became planets. What force was responsible for the collisions between these particles?

• gravity

• solar radiation

• seismic waves

• radioactive decay

• A. use of cameras and telescopes DURING the formation of the solar system

• B. sending teams of astronauts to each planet to gather samples from the planet

• C. sending astronauts to visit the sun and gather samples and record measurements

• D. observations of other stars and supernovas experiencing collisions and other movements

• A. This stage shows the contracting and cooling of a cloud.

• B. This stage shows a large collapsing cloud of gas and dust.

• C. This stage shows the collision and fusion of particles forming several large clumps.

• D. This stage shows the spinning and flattening of a nebula that throws off gaseous material.

How long did it take for the solar system to form?

• 5 million years

• 50 million years

• 500 million years

How was our moon formed?

• the Earth's gravity grabbed the moon as it was passing by

• the Earth and moon formed at the same time

• Theia a planet smashed into our Earth causing debris to fly out which formed the moon

• A. How large is the planet?

• B. How long does it take the planet to orbit the sun?

• C. How much does the planet tilt on its axis of rotation?

• D. How long does it take the planet to rotate on its axis?
