The scientific study of the stars and outer space.
A glowing ball of gases; the sun is our closest _________.
A huge star system held together by gravity that covers many light-years of space; we are in a spiral _____ = Milky Way.
The complete turn of a planet on its axis (known as an earth day).
This is the angle at which a planet rotates around it's axis as compared to an imaginary line perfectly perpendicular to the Sun--23.5 degrees for Earth -- determines the seasons.
Each complete orbit that a planet makes around the sun (an earth year).
The hemisphere tilted toward the sun receives the most direct sunlight in this season.
The hemisphere tilted away from the sun does not receive as much direct sunlight during this season.
This attraction of the one mass on another mass: this attraction of the sun keeps the planets in orbit.
The four small, dense, relatively close together planets, rocky and earth-like in composition (mercury, venus, earth, mars).
The 3rd planet from the sun; only planet on which man survives in his natural state; water exists in a liquid state; gravity holds atmosphere in place; one natural satellite, gift from God.
The planets that are made of hot or frozen gases (also called Jovian planets--Jupiter, Saturn, Uranus, and Neptune).
Five small planets that orbit the sun, are roughly spherical, but have not cleared their orbital neighborhood and may orbit with other objects; Pluto, Haumea, Makemake, Eris, and Ceres.
phases of the moon
This cycle is caused as the moon revolves around Earth and different areas of the moon are lighted by the sun; waxing means growing in lit areas and waning means shrinking in lit areas.
The unofficial race between the USSR/Russia and the United States to gain control of space.
The system responsible for taking in oxygen and releasing carbon dioxide waste; nostril, pharynx, larynx, bronchi, bronchioles, alveoli (in lungs).
(aka cardiovascular system) This system consists of the heart, blood, and blood vessels and transports substances such as oxygen, carbon dioxide, and nutrients in the body.
Body system that breaks down food into simpler forms through both chemical or mechanical digestion and absorption of nutrients.
central nervous system (CNS)
Composed of the brain and the spinal cord. This is the part of the nervous system that does most of the information processing.
peripheral nervous system (PNS)
Contains all the neurons involved in receiving information and sending it on to the spinal cord and brain. Includes the autonomic and somatic nervous systems.
The body's "slow" chemical communication system; a set of glands that put hormones into the bloodstream to go to target cells and respond (controls growth, reproductive hormones, etc.).
Describes the fact that God made humans to reflect in a limited way certain aspects of His own being, such as intelligence, emotions, and will.
A disease that can be spread from one person or species to another; spreads through a vector, contact, air, water, or food (ex. flu, cold, malaria)
Microbes that cause communicable diseases (bacteria, viruses, fungi, or protists)
a disease that is not transmitted by another person, a vector, or the environment--may be genetic or a result of health habits (ex. cancer, heart disease)
The cells and tissues that recognize and attack foreign substances in the body.
