Answer:
B. As new rocks are formed along mid-ocean ridges, older rocks are pushed down deep into the Earth into ocean trenches.
<h2>
Why is the Earth not getting larger if the sea floor is slowly spreading?</h2>
Mainly due to the Atlantic experiencing seabed expansion. The sea bottom is subducting, or moving underground, in the Pacific. This is how the Earth's tectonic plates and geological activities function. The top side of the mantle travels to the bottom at one end and to the top at the other, similar to a conveyor belt. This explains why there are volcanoes, why continents drift, and why our planet's surface is continually changing over the span of millions of years.
Therefore, the planet is not getting bigger because its surface is constantly recycling itself.
Answer: Forests are a stabilizing force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth.

Answer:
The correct option is: c.prevent food from entering the lungs
Explanation:
Trachea is a cylindrical cartilaginous hollow pipe that branches into the two primary bronchi of the lungs.<u> It is the passage of air that connects the larynx to the lungs and thus it is also known as the windpipe</u>.
The trachea is lined with a mucous-membrane which moistens and protect the airway.<u> It also traps and prevents the dust and other contaminating particles from reaching the lungs.</u>
Convection cell
Air Pressure and Winds
Warm air rises, creating an upward-flowing limb of a convection cell (Figure 15.19). Upward flowing air lowers the air pressure of the area, forming a low pressure zone. The rising air sucks in air from the surrounding area, creating wind.
