Trees, such as those in the deciduous forest, are very important to the environment. If the number of trees on earth continues to decrease significantly, what might be the result? (Site 1)
Answer:
more carbon dioxide would build up without the tress to recycle it and many animals would lose their habitats
Answer:
Animals will begin to migrate towards residential areas if the number of trees on the planet continues to decline, as their natural habitat would be destroyed. There are numerous plant species that can be used as a source of medicine for disease prevention and treatment. Trees provide a significant amount of oxygen to the environment. Some deciduous forest trees grow near rivers, preventing soil erosion by attaching dirt to the plant's roots. Cottonwood, mountain ash, and fruit trees are commercially important trees. If there is a considerable reduction in the quantity of trees, all of the above benefits of trees will be lost.

Hi, so i was wondering How long does Mars have to travel around Earth to make it's complete rotation?
Answer:
24 hours and 37 minutes
Explanation:
At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.
Answer:
The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
