100+ Free MTTC Earth/Space Science (020) Practice Questions

Foundations of Scientific Inquiry (Subarea I)

Principles and procedures for conducting scientific research, including experimental design, variables, and data analysis; the materials, methods, and equipment used in earth/space science; laboratory and field safety; the nature and history of scientific thought; connections between earth/space science and contemporary societal issues; and interrelationships among the life, physical, and earth/space sciences.

Physical and Historical Geology (Subarea II)

Earth's structure and interior; minerals and their properties; the rock cycle that produces igneous, metamorphic, and sedimentary rocks; plate tectonics; the causes and consequences of volcanism and earthquakes; weathering, erosion, and deposition; the geologic time scale and relative and absolute dating methods; and the formation and use of geologic resources and human impacts.

Oceanography and Freshwater Systems (Subarea III)

Physical components and processes of marine systems, including ocean zones (littoral, pelagic, benthic), currents, tides, waves, and salinity; the distribution of fresh water and the processes of the hydrologic cycle; groundwater, the water table, and aquifer types; the characteristics and processes of freshwater systems and watersheds; and relationships between the hydrosphere and human activity.

Meteorology (Subarea IV)

Atmospheric structure and composition; weather and climate processes; the formation of clouds, precipitation, and condensation; humidity, air pressure, and wind; air masses, fronts, and severe weather such as hurricanes and thunderstorms; Earth's climate systems and the factors that influence them; and connections between the atmosphere and human activity.

Astronomy (Subarea V)

Characteristics of the Sun-Earth-Moon system, including moon phases, eclipses, tides, and seasons; the components of the solar system and the physical laws (such as Kepler's laws and gravitation) that govern motion; stellar evolution, the Hertzsprung-Russell diagram, galaxies, and the formation of the universe; and the history of astronomy and space exploration.
