weather is per day and climate is over 30 years
Earth’s atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. This makes the existence of life possible on Earth. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide. The amount of carbon dioxide on these planets can range from 95% to 97%. This may be the reason no life exists on these planets.
The atmosphere of Venus is about 96 per cent carbon dioxide, with surface temperatures around 737 K (464 °C, or 867 °F).
Venus itself rotates only once every 243 Earth days.
Mars, in contrast, has a thin atmosphere composed of about 95 per cent carbon dioxide, with the remainder being mostly diatomic nitrogen.
Answer:
The Earth is constantly changing its position with the sun as the Earth tilts in relation to the sun. This creates the differences in the seasons and the annual warming and cooling cycles of the Earth’s Northern and Southern Hemispheres.
Explanation:
- When the North Pole tilts most toward the sun, the Northern Hemisphere experiences summer.
- Spring and Autumn) occur midway on the Earth’s journey from winter to summer and from summer to winter.
- On March 20 or 21 of each year, the Earth reaches the vernal equinox, which marks the arrival of Spring in the north and Autumn in the south. The autumnal equinox occurs on September 22-23 and marks the arrival of Fall in the north and Spring in the south.
- When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, and this has nothing to do with how close or far the Earth gets to or away from the Sun in its orbit. It’s all because the Earth is tilted on its axis.
The answer to the question is true
Answer:
Explanation:
Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. ... Mantle convection causes tectonic plates to move around the Earth's surface.
