A.
Sound absorption depends more on the thickness of a material than its color.
Answer:
i guess option b is correct.
Answer:
PRECISSION
Explanation:
The movement of the Earth's axis is called precession.
This movement is caused by the gravitational attraction of the Sun and the Moon on Earth.
Near the year 130 B.C. Hipparchus was the first to estimate the precision of this axis, whose period is about 26,000 years.
Answer:
Yes. Due to the magma in the mantle, the tectonic plates in the upper crust of the earth move because of a process called *convection. The heat from the magma causes the tectonic plates to move at a very very slow rate
*An example of this is when you're cooking food in a pan. The food is getting hotter because the heat rising from the stove heats the pan.
In simpler terms: Stove ~~ Pan --> hot food
*There is no direct contact between the stove and the pan which is a defining feature of convection.
Answer: The availability of sufficient nutrients and water, as well as sunlight for photosynthetic forms, is, however, the only major factor restraining successful and heavy protist colonization of practically any habitat on Earth.
Explanation: In recent years, a contribution of geographic distance and dispersal barriers to distribution patterns of protists and bacteria has been demonstrated. Organismic interactions such as competition, predation and mutualism further modify community structure and maintenance of distinct taxa.
