Most types of pneumonia cause fever, cough with sputum (coughed-up mucus), shortness of breath and fatigue. In older patients, fatigue or confusion can be the only or most noticeable symptom. In viral pneumonia, a dry cough without sputum is more common. Your doctor first will ask about your symptoms.

Igneous Rocks. Of the three principal rock types (igneous, sedimentary, and metamorphic), igneous rocks can be thought of as primary rocks because they crystallize from a liquid. Sedimentary and metamorphic rocks, which we will study later, may be thought of as derivative rocks. Igneous rocks are rocks formed from the crystallization of a liquid (molten rock). Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth's surface.
