Geography
True
A Geographic Information System (GIS) can display and combine thematic map layers digitally, which helps researchers find and analyze spatial and temporal changes and patterns on Earth's surface.
True
A broader knowledge of physical geography can help us understand how to live sustainably and to negatively impact the natural world as little as possible.
True
A map projection is a representation of a spherical grid onto a flat surface, such as a piece of paper.
False
A map scale is an expression of the relationship between the amount of travel time between two points on a map and the actual time in decimal minutes.
True
All of the three major perspectives in physical geography use the scientific method to guide learning about the processes and features on Earth.
True
Compared to oceanic crust, continental crust is thicker and less dense.
False
Continental crust is a thick, dense layer made of basalt rock.
False
Density and temperature decrease as depth in Earth increases.
True
Digital mapping, GPS, GIS, and remote sensing have revolutionized the field of geography, but the basic principles of cartography are still applicable today.
False
Earth's outer core is solid rock.
True
Extrusive igneous rocks are formed from cooling lava, while intrusive igneous rocks are formed from cooling magma.
True
Geography is commonly considered the spatial discipline because it is concerned with phenomena on Earth's surface.
False
Global positioning systems are absolutely essential for knowing where you are on the Earth so that you can create a map.
False
In general, extrusive igneous rocks are composed of mineral grains visible to the unaided eye, whereas mineral grains in intrusive igneous rocks are too small to be seen without magnification.
False
In the winter, the reason Earth surface temperatures are colder in the Northern Hemisphere is because the planet is twice as far from the Sun as it is during the summer.
False
Metamorphic rocks form when pre-existing rocks melt and cool.
False
Minerals are composed of rocks.
True
One requirement for a substance to be classified as a mineral is for it to be inorganic, but it is possible for rocks to contain some organic matter.
False
Only one of the major structural zones inside Earth is liquid, and that zone is the mantle.
True
Seismic waves reveal Earth's inner core is a solid, dense layer of iron and nickel.
False
The Earth's rotation has very little to do with how much solar energy is received by the Earth at any given place on the planet.
True
The Sun is the center and the unifying body of our solar system.
True
The Tropic of Cancer and the Tropic of Capricorn are imaginary lines marking the northern-most and southern-most, respectively, latitude at which the Sun's rays can ever be directly overhead.
True
The asthenosphere is part of the upper mantle on which pieces of the lithosphere move.
False
The crust is about as thick as the mantle
True
The energy emitted by the Sun comes from fusion (thermonuclear) reactions taking place in its core.
False
The horizontal layering in sedimentary rocks is called foliation.
True
The rock cycle illustrates the processes that generate, alter, transport, and deposit mineral materials to produce different types of rocks.
True
Topographic contour lines are isolines connecting points on a map that are at the same elevation above or below mean sea level.
TRUE
Understanding physical geography can help us make more informed decisions about, for example, where to build large commercial centers so that they are in danger from as few natural hazards as possible.
area identified by certain characteristics it contains that makes it distinctive and separates it from surrounding areas.
