Which four major spheres are commonly used to describe the Earth
system?
A. Lithosphere, hydrosphere, atmosphere, and biosphere
B. Crust, mantle, core, and atmosphere
C. Troposphere, stratosphere, mesosphere, and thermosphere
D. Ocean, continent, mountain, and plain
Answer: A. Lithosphere, hydrosphere, atmosphere, and biosphere
Rationale: The lithosphere represents Earth's solid outer portion, the
hydrosphere includes Earth's water, the atmosphere consists of gases
surrounding Earth, and the biosphere encompasses living organisms.
These spheres interact continuously, making Earth an interconnected
physical system.
Which sphere includes Earth's rivers, lakes, groundwater, glaciers, and
oceans?
A. Biosphere
B. Hydrosphere
C. Lithosphere
D. Atmosphere
,Answer: B. Hydrosphere
Rationale: The hydrosphere includes Earth's water in liquid, solid, and
gaseous forms. Oceans contain most of Earth's water, while freshwater
occurs in glaciers, groundwater, lakes, rivers, soil moisture, and the
atmosphere.
Which branch of physical geography focuses primarily on Earth's
landforms and the processes that create and modify them?
A. Climatology
B. Biogeography
C. Geomorphology
D. Hydrology
Answer: C. Geomorphology
Rationale: Geomorphology examines landforms and the processes
responsible for their development and modification. These processes
include weathering, erosion, mass movement, tectonic activity, and
deposition.
What is the primary distinction between weathering and erosion?
A. Weathering transports material, whereas erosion breaks it apart
B. Weathering breaks down material in place, whereas erosion involves
its removal or transport
C. Weathering occurs only in deserts, whereas erosion occurs only near
oceans
,D. Weathering affects rocks, whereas erosion affects only soil
Answer: B. Weathering breaks down material in place, whereas
erosion involves its removal or transport
Rationale: Weathering is the breakdown or alteration of Earth
materials at or near the surface without requiring transportation.
Erosion involves the removal and movement of weathered material by
agents such as water, wind, ice, or gravity.
Which process is an example of physical weathering?
A. Oxidation
B. Hydrolysis
C. Frost wedging
D. Carbonation
Answer: C. Frost wedging
Rationale: Frost wedging occurs when water enters cracks, freezes,
expands, and places pressure on the surrounding rock. Repeated
freezing and thawing can progressively widen cracks and fragment the
rock without changing its chemical composition.
Which chemical weathering process is primarily responsible for the
formation of rust on iron-bearing minerals?
A. Oxidation
B. Frost action
, C. Abrasion
D. Exfoliation
Answer: A. Oxidation
Rationale: Oxidation occurs when minerals react chemically with
oxygen. Iron-bearing minerals can oxidize and produce iron oxides,
commonly recognized as rust-colored materials.
Which combination represents major controls on weathering?
A. Rock characteristics, climate, hydrology, topography, and vegetation
B. Latitude, longitude, tides, ocean currents, and earthquakes
C. Population, industry, transportation, trade, and migration
D. Pressure, salinity, tides, ocean depth, and wave height
Answer: A. Rock characteristics, climate, hydrology, topography, and
vegetation
Rationale: Weathering intensity depends on the characteristics of the
material being weathered and environmental conditions. Climate,
water availability, landscape position, and vegetation can strongly
influence how rapidly physical and chemical weathering occur.
What is abrasion?
A. Chemical alteration caused by oxygen
B. Mechanical wearing away caused by transported particles
C. Freezing of groundwater
