Because most cigar and pipe smokers do not ______, as a group they have a lower risk of cancer than cigarette smokers.
Artyom0805 [142]

Because most cigar and pipe smokers do not<u> </u><u>inhale the smoke</u> , as a group they have a lower risk of cancer than cigarette smokers.

The cigarettes, cigars, and pipe tobacco are made out of dried tobacco leaves. The other substances are usually added for flavor and to make smoking more gratifying. The smoke from these products is a complex mixture of chemicals produced by flaring tobacco and its additives.

There are at least 70 known chemicals to cause cancer. These cancer-causing chemicals are referred to as carcinogens.

It is so because cigars and pipes are usually believed to be less harmful way than to smoke tobacco. It was once a trend to use cigars in the 1990s, luring/dragging the young and the old.

Most of the people think cigars are less harmful to their health, but they actually pose the same risk for oral cancer as cigarettes do. Many cigar smokers don't inhale the smoke, but still the risk for oral, throat, and esophageal cancer is alike as for cigarette smokers.

Tectonic plates are pieces of the ________ that float on the more fluid ________ below. A. mantle; crust B. asthenosphere; litho
Soloha48 [4]

Answer:

The answer is E.) Lithosphere, Asthenosphere.

Explanation:

Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.

From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:

i) the crust

ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)

iii) the outer core

iv) the inner core.

The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers

( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
