About This Presentation

How the moon was formed


Slide Content

Unit 6 Sound And Space

Starter activity Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.

6.3 Formation Of the moon Learning objective: Describe evidence of the collision theory for the formation of the moon.

T he Collision theory  is another theory of  how the Moon was formed. There is more evidence that supports the collision theory than any other current theory. The collision theory refers to a collision that happened relatively soon after the formation of the Solar System. A newly formed planet, about the same size as Mars, collided with the newly formed Earth. How was the moon formed​

SCIENTISITS HAVE CALLED THE COLLIDING PLANT THEIA. THE PICTURE- DRAWN BY AN ARTIST- SHOWS WHAT THE COLLISION BETWEEN EARTH AND THEIA MAY HAVE LOOKED LIKE

Stages on  how the moon was formed

Evidence that supports the collision theory The Moon is less dense than the Earth samples of rock from the Moon show that its surface was once molten. The Moon has a small iron core, like the Earth. There is evidence outside the Solar System of similar collisions causing rings of rock and dust. The collision theory fits with the theory of how the Solar System was formed. The composition of rocks on the Earth and the Moon are the same. Evidence that contradicts the collision theory The surface of the earth does not appear to ever have been molten. A collision that formed the Moon would have caused the surface of the Earth to melt. The surface would have later Solidified. Venus has no moon. Collisions in the early years of the Solar System would and been common and scientists would have expected Venus to have moon formed in the same way. The composition of rocks on the moon would be expected be more like rocks on Theia than rocks on Earth.

Question. Does the Moon have a gravitational pull ? Yes, it has a gravitational pull of about 1.62 m/s². ​

Moon facts and space facts The Moon has quakes too. There is water on the Moon. SPACE IS COMPLETELY SILENT. ONE MILLION EARTHS CAN FIT INSIDE THE SUN.

  Quiz time  q1 The collision theory suggests that an object called Theia collided with Earth. Which of these planets is closest in size to Theia? Write one letter. A) Mars B) Earth C) Neptune D) Jupiter Q2 Which of these statements could explain why the composition of rocks on the Earth and on the Moon is very similar? Write one letter. A ) The Moon is mostly formed from Theia's rocks and the Earth only has a small quantity of Theia's rocks. B) The Earth is mostly formed from Theia's rocks and the Moon only has a small quantity of Theia's rocks. C) Rocks from Theia and Earth were completely mixed during the collision.
