It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Answer: Silt, Sand and Gravel
Explanation:
When rock wears out due to process of weathering, it breaks down into pieces or sediments that ranges from microscopic grains to very large grains. Now,
Sediment smaller than 0.0625 mm in diameter cannot be seen unaided and is called Silt
Sediment between 0.0625 and 2 mm in diameter generally is known as Sand which refers to collection of fine, medium, and coarse sand.
Grains larger than 2 mm are called Gravel and range from 2 mm up to 64 mm.
Answer:
Knowing that the temperature at sea level (0 m) is 20 ° C, we will calculate the air temperature at. The altitude of 3500m.
According to the vertical thermal gradient, the air temperature decreases by 6 ° C at 1000m alt.
1000 m .... 14 ° C (20-6 = 14)
2000 m .... 8 ° C (14-6 = 8)
3000 m ... 2 ° C (8-6 = 2)
3500 m .... - 1 ° C (2-3 = -1
