A comprehensive geography study of the physical landscapes, major river systems, and diverse climate regions of the United States and Canada. Features both a standard interactive reading guide and an Emergent Bilingual adapted version with visual and linguistic scaffolds.
Very cold winters, short cool summers. Frozen ground.
Pacific Coast
Mild temperatures, lots of rain from ocean winds.
Great Plains
Continental climate: cold winters and hot summers. Good farming.
Northeast Region
Four clear seasons: snow in winter, warm humid summers.
Southern US
Humid subtropical: mild winters, hot and humid summers.
Hawaii & S. Florida
Tropical: warm temperatures and high humidity all year.
Visual Guide: The Rain Shadow Effect (Sombra de Lluvia)
Visual Scaffold
Step 1: Ocean Air
Moist air travels from the Pacific Ocean.
Step 2: West Side
Air rises over mountains, cools & drops rain.
Step 3: High Peak
Clouds lose moisture at mountain crest.
Step 4: East Side
Dry air sinks. Deserts form (Rain Shadow).
Q5 Why do deserts form east of Pacific mountain ranges? Word Bank: blocks • rain • dry • desert
Deserts form east of the Pacific mountain ranges because the mountains moist ocean air. The clouds drop all their on the west side. By the time air reaches the east side, it is , which creates a .

Core Geography Concept
Four-Step Scientific Explanation:
Ocean Winds: Prevailing westerly winds carry moisture-laden clouds from the Pacific Ocean over coastal land.
Orographic Lift: Mountain barriers (Sierra Nevada, Cascades) force the air upward. As air rises, it expands and cools, precipitating rain and snow on the western (windward) slopes.
Moisture Loss: Clouds shed nearly all moisture by the time they reach the mountain crests.
Rain Shadow Desert: Dry air sinks down the eastern (leeward) slopes, compressing and warming, which inhibits cloud formation and creates arid deserts (e.g., Great Basin, Mojave).
Q6 Climate & Human Settlement / Agricultural Patterns
Model Response
Great Plains: A continental climate with warm summers and moderate rainfall combined with rich prairie soils makes this region the agricultural "breadbasket" for commercial wheat, corn, and livestock farming, supporting dense rural communities and transport hubs. Northern Canada & Alaska: Extreme subarctic/tundra conditions, permafrost (permanently frozen subsoil), and short growing seasons prevent large-scale commercial farming, resulting in sparse human settlement concentrated in mining, administrative, or indigenous fishing communities.
Differentiated Scaffolding for Emergent Bilinguals (WIDA Levels 1-4)
WIDA Levels 1-2 (Entering / Emerging)
Direct students to use the Spanish cognate bank (tributario, escudo, llanura).
Have students point to and trace arrows on the visual Rain Shadow diagram.
Accept single-word or short-phrase answers using the provided word banks.
WIDA Levels 3-4 (Developing / Expanding)
Require complete sentences using the provided sentence frames and stems.
Encourage the use of transitional phrases: "As a result," "Because of this," "In contrast."
Ask students to explain *why* the Great Plains can feed millions while northern Canada cannot.
