【People's Education Press】Junior High School Geography, Grade 7, Semester 2: Exploring the Eastern Hemisphere – Understanding Regional Differences Through Geographic Coordinates

Welcome to your journey through the Eastern Hemisphere! We're not just looking at maps—we're decoding Earth's 'secret language.' Geographic coordinates—latitude and longitude—determine a region's sunlight exposure, precipitation patterns, and even its fate. In the Eastern Hemisphere, these differences are especially pronounced.

Core Regional Characteristics

Western Europe: Located inthe western part of Europe, bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. The terrain here islow-lying, making it themost concentrated region of developed nations worldwide.
Sub-Saharan Africa: Spanning the equator with widespread tropical climates; according toFigure 8.30, this region is rich incoffee,bauxiteand abundantbiological resources.
The Middle East and Australia: Geographic coordinates determine the distribution ofwater resourcesdistribution disparities, thereby influencing each region's 'pillar of national economy', such as oil production in the Middle East and mining and sheep farming in Australia.

A Modern Perspective on Geographic Determinism

Geographic location is more than just coordinates—it means Western Europe enjoys a temperate oceanic climate extending deep inland, while Australia has preserved unique ancient species due to its long geological isolation (see Figure 8.35).

QUESTION 1

Based on Figures 8.28 and 8.29, discuss the relationship between local housing and climate.

Local homes are mostly flat-roofed, reflecting the region’s low rainfall and dry climate.

Local homes are often stilt houses, reflecting the region’s consistently hot and rainy conditions year-round.

Local homes have steeply pitched roofs, reflecting the region’s heavy winter snowfall.

QUESTION 2

Oil from the Middle East is exported mainly via tankers from ports along the Persian Gulf coast. Based on the three main shipping routes, identify which region Route C primarily reaches?

East Asia (Japan, China, etc.)

Western Europe and North America

Sub-Saharan Africa

QUESTION 3

Which of the following descriptions about Western Europe is incorrect?

is the most concentrated region of developed nations worldwide

has highlands as its dominant terrain and extremely high average elevation

borders the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south

QUESTION 4

In international trade, what products does Sub-Saharan Africa primarily export? (Refer to Figure 8.30)

high-tech electronic products

primary mineral products and tropical cash crops (e.g., bauxite, coffee)

luxury cars and heavy machinery

QUESTION 5

Why is Australia called the 'lonely continent'? What is the relationship with its geographic location?

Because it lies in the Northern Hemisphere and is isolated from other continents

Because it is isolated in the oceans of the Southern Hemisphere, with a simple natural environment and slow biological evolution

Because it is connected to Antarctica by land
