Unit 1

Chapter 1: Geography and History

-People have been around for over 2 million years.

-The land has greatly influenced people’s lives.

 

Section 1: Five Themes of Geography

-Geography-is the study of the Earth and of the ways people live and work

 on it.

 

Location

-Where is it?

-Absolute location - exact place on Earth (only one spot).

-Relative location – position relative to other things (ex. near the store).

 

Place

-Physical and human characteristics of an area.

-Includes land, climate, elevation, cities

 

Human/Environmental Interaction

-How humans adjust to an environment.

-How humans modify their environment to meet their need.

 

Movement

-How ideas (communication) materials (export/import) and people

emigrant/immigrant) move around to different places.

 

Regions

-Areas that share a characteristic.

 

 

Section 2: Land, Water and Climate

-Lots of differences.

 

Landforms

-4 main landforms: mountains, hills, plateaus, and plains.

-elevation – height above sea level.

-relief – changes in height.

-mountains-highest high relief, medium-lower moderate relief, plains-low

low relief, and plateau-medium low relief.

 

Surface Changes From Inside the Earth

-Some of the ways the land changes are because of forces inside the Earth.

-Earth made up of following parts.

          -Core - center- solid and molten rock.

          -Mantle - mostly, hot solid rock, outer part liquid.

          -Crust - thin layer of rock floating on mantle.

-Crust made up of different tectonic plates  (TP) that move separately.

-Movement of TP called continental drift (CD).

-Movement of plates cause pressure which leads to volcanoes and

earthquakes.

 

Surface Changes From Outside the Earth

-Erosion is the process by which ice, wind, and water reshape the land.

-Examples: glaciers from the Ice Ages, dust storms, and river canyons.

 

Landforms in History

-Landforms have helped to determine where people live and how they

communicate and relate to each other.

 

Waterways

-70% of Earth covered by water.

-Oceans, seas, rivers, and lakes all are waterways

-River system – a river and all of the streams (tributaries) that flow into it.

 

Waterways in History

-People generally have lived near water for travel, drinking, and food.

 

Climate and the Sun

-Climate – the pattern of weather over a long period of time.

-The sun has a huge effect on climate as the earth orbits sun.

-N. and S. Poles get little direct sunlight so are colder, equator gets a lot so

warmer, this is due to tilt in Earth’s axis.

 

Climate Zones

-Latitude – distance from the Equator.

-Tropical zone – between Tropics and Equator, hot all year.

-Temperate zone – between Tropics and Arctic/Antarctic Circles (A/AC),

warm in summer and cool in winter.

-Polar zone – Above/Below A/AC, cold all year round.

 

Climate, Water, and Wind

-Water can affect climate through ocean currents (streams of water in ocean).

-Wind can affect climate

          -Prevailing winds - Winds that go same way all the time.

          -Monsoons – Winds that shift directions.

 

Climate and Altitude

-Higher the altitude the cooler the temperature

-Precipitation - falling of moisture such as snow and rain.

-Mountains can effect precipitation or lack of it.

 

Climate in History

-Climate helps to determine where people live.

 

Section 3: Natural Resources

-Natural Resources (NR) are materials found in nature.

 

Kinds of Natural Resources

-Air, water, soil, and sunlight are essential natural resources.

-Minerals – nonliving substances living beneath the earth’s surface.

-Minerals become valuable when are needed and rare.

-Renewable resources can be replaced.

-Nonrenewable resources can not be replaced.

-Fossil fuels (fuels made from dead plants and animals) and minerals are

nonrenewable.

 

Natural Resources in History

-Location of natural resources can also determine where people live.

 

Section 4: Legends

-Legends are stories passed down through generations in most cultures.

-Archaeologists – Scientists who study the remains of past human life

-Anthropologists – Scientists who study the origin and developments of

humans.

 

Section 5: Archaeology

- Archaeology is the study of the remains of past human life and cultures.

- People student artifacts (things made by humans).

- Scientists can learn a lot by looking at artifacts.

Dating Archaeological Remains

- Scientists divided human history naming them by the materials they used

          (Stone, Bronze, and Iron).

- Able to date things by tree rings and Carbon-14 dating process.
