Слайд 2 THE DISCIPLINE OF GEOGRAPHY
Geography is concerned with the

THE DISCIPLINE OF GEOGRAPHY	Geography is concerned with the physical and human

physical and human processes that differentiate places on Earth

and make them unique.

In this way, geography provides a fundamental understanding of the spatial connections among human activities as they relate to the Earth’s physical landscape.

Слайд 3 THE DISCIPLINE OF GEOGRAPHY
Systematic geography is often divided

THE DISCIPLINE OF GEOGRAPHY	Systematic geography is often divided into two broad

into two broad areas – human and physical geography.



Human geography deals with social, economic, and behavioral processes that differentiate places.

Physical geography covers the atmosphere, terrestrial and maritime environments on local, regional, and global scales.

Слайд 5 THE DISCIPLINE OF GEOGRAPHY
Meteorology deals primarily with the

THE DISCIPLINE OF GEOGRAPHY	Meteorology deals primarily with the processes that cause

processes that cause short-term fluctuations in those properties of

the atmosphere that form the basis of daily weather reports (Chapters 3 to 7).

Climatology describes the results of these processes in terms of their variability in space and time (Chapters 8 to 10).

Geomorphology is the science of Earth surface processes and landforms (Chapters 11 to 18).


Слайд 6 THE DISCIPLINE OF GEOGRAPHY
Geography of soils includes the

THE DISCIPLINE OF GEOGRAPHY	Geography of soils includes the study of the

study of the distribution of soil types and properties

and the processes of soil formation (Chapter 19).

Biogeography is the study of the distribution of organisms and the processes that produce these spatial patterns (Chapters 20 and 21).

Слайд 7 THE DISCIPLINE OF GEOGRAPHY
Water resources encompasses the basic

THE DISCIPLINE OF GEOGRAPHY	Water resources encompasses the basic study of location,

study of location, distribution and movement of water (Chapters

15 and 16).


Слайд 8 THE DISCIPLINE OF GEOGRAPHY
An understanding of physical processes,

THE DISCIPLINE OF GEOGRAPHY	An understanding of physical processes, such as floods,

such as floods, earthquakes, and landslides, provides the background

for assessing the impact of natural hazards.

Слайд 10 Tools in Geography
Geographic Information Systems (GIS) are spatial

Tools in Geography	Geographic Information Systems (GIS) are spatial databases that rely

databases that rely on computer analysis and manipulation to

display up-to-date spatial information (Chapter 2).




Слайд 11 Tools in Geography
A map is used to display

Tools in Geography	A map is used to display spatial information.	The art

spatial information.

The art and science of map-making is called

cartography (Chapter 2).



Слайд 12 Tools in Geography
Another important technique for acquiring spatial

Tools in Geography	Another important technique for acquiring spatial information is remote

information is remote sensing, in which aircraft or spacecraft

provide images of the Earth’s surface (Chapter 3).



Слайд 13 Tools in Geography
Using mathematics and computers to model

Tools in Geography	Using mathematics and computers to model geographic processes is

geographic processes is a powerful approach to understanding both

natural and human phenomena.

Statistics provide methods to analyze data to assess differences, trends, and patterns.



Слайд 15 PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGE

PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGEGlobal Climate Change 	Over

Climate Change

Over the past decade, many scientists have

come to the opinion that human activity has begun to change the Earth’s climate.

Слайд 17 PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGE
Biodiversity

PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGEBiodiversity 	The diversity of



The diversity of Earth’s plants and animals which is

an immensely valuable resource (Chapters 21 and 22).

Слайд 18 PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGE
Pollution

PHYSICAL GEOGRAPHY, THE ENVIRONMENT, AND GLOBAL CLIMATE CHANGEPollution 	Unchecked human activity



Unchecked human activity can cause environmental pollution in the

context of air and water (Chapters 4 and 15).

events

Floods, fires, hurricanes, and earthquakes, have great and

long-lasting impacts on human and natural systems.

Слайд 21 ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY
Recurring principals and ideas

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY	Recurring principals and ideas in physical geography

in physical geography are used to organize our accumulated

knowledge into realms which encompass the major components of the planet.

Lithosphere

systems approach emphasizes how and where matter and energy

flow in natural systems.

Слайд 28 ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY
Flow systems describe how

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY	Flow systems describe how matter and energy

matter and energy move from one location to another

over time.

Flow systems have a structure of interconnected pathways and require a power source (energy: kinetic, mechanical, heat, radiant, potential, stored, chemical).

Слайд 29 ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY
Open and Closed Flow

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHYOpen and Closed Flow Systems	Flow systems have

Systems

Flow systems have inputs and outputs.

Some flow systems are

open since they have inputs and outputs of energy and matter.

Some flow systems are closed in which materials move endlessly in a series of interconnected paths or loops (hydrologic cycle).

Слайд 30 ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY
The hydrologic cycle, in

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY	The hydrologic cycle, in which water circulates

which water circulates between the biosphere, atmosphere, lithosphere, and

hydrosphere, is and example of a closed system in physical geography.

Слайд 32 ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHY
Feedback and Equilibrium in

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHYFeedback and Equilibrium in Flow Systems	Flow system

Flow Systems

Flow system feedback occurs when the flow in

one pathway acts either to reduce or increase the flow in another pathway.

Flow system equilibrium refers to a steady condition in which the flow rates in a system’s various pathways do not change significantly.

ORGANIZING INFORMATION IN PHYSICAL GEOGRAPHYTime Cycles	Any system, whether open or closed,

open or closed, can undergo a change in flow

rate (time cycle) of energy or matter within its pathways.
