Explanation:
The Earth is a planet which is a tern used to describe large bodies that revolves around a star.
The star around which the Earth revolves or travels around is the Sun, and the path of the Earth's motion is known as the Earth's orbit. The time it takes the Earth to travel round the Sun is 365 1/4 (365.25) days
The Moon is a natural satellite of the Earth, therefore, the Moon travels or revolves round the Earth. The Moon is about 27% the size of the Earth and it takes the Moon about 27.3 days to travel around the Earth.
Answer:
F means oxygen from plant goes into the atmosphere.
Explanation:
2. matter is conserved in this process because plants take carbon dioxide from the atmosphere for photosynthesis then produces oxygen into the atmosphere, animals then feed on plants and later the animal's faecal matter is released into the soil and even when animals die, microorganisms in the soil break I down into absorbable form for plants use. which makes matter conserved.
3. mater is in a circular state from atmosphere to plants to animals to soil then absorbed by plants to restart the process again.
Answer:
According to the picture, during a solar eclipse the moon must be in position A, interposed between the sun and the earth.
Explanation:
A solar eclipse is due to the interposition of the moon between the sun and the earth, which produces that the solar rays do not reach certain points of the planet.
The lunar phase that is shown during a solar eclipse is the new moon phase, because the satellite does not show the side illuminated by the sun. At this point, the moon must be close to the solar orbital plane for the phenomenon to occur.
