Shapes on Our Earth
Earth has many different shapes of land. We call these shapes landforms .
A mountain is the tallest landform. It is steep and rocky. Some tall mountains even have cold snow on their tops!
A hill is high too, but it is smaller and rounder than a mountain.
A valley is the low land between mountains or hills. Water often runs through a valley.
A plain is flat and wide. It has plenty of open space for grass and farms.

Teacher Notes • First-Grade Instructional Tips
Sight Words & Decodables: Point out high-frequency words before reading: shapes, land, water, between, smaller . Model blending the compound word land + form .
Common Misconception: Students often mistake valleys for rivers. Emphasize that a valley is the land , and water simply flows across it because it is lower than the surrounding hills.

Life in the Valley
A valley is a low piece of land. It sits down low between hills or tall mountains.
Many valleys have a fresh river or stream flowing right through the middle. Water brings life to the valley!
Plants, trees, and wildflowers love to grow here because the soil is rich and dark. Many farmers build farms in valleys to grow yummy food.
Some valleys are deep and shaped like the letter V . Flowing river water carved them out over a very long time!

Architects of the Earth
Forces That Shape Our Surface
Earth’s surface is constantly being shaped into natural physical features called landforms . Mountains are the highest landforms, towering thousands of feet with steep, rocky slopes and sharp peaks. Many mountains form when giant slabs of crust, called tectonic plates, collide slowly over millions of years. Nearby, smaller rounded elevations with gentler slopes are known as hills .
Between mountains or hills lie valleys —low-lying depressions carved over millennia by rushing rivers or moving glaciers. Further out, vast expanses of flat or gently rolling ground form plains . Ancient rivers deposited rich sediment across these areas, producing fertile soil perfect for prairies and farms. Continuous forces like weathering, erosion, and tectonic uplift keep Earth’s surface ever-changing.
1. According to the text, how do many mountain ranges form?
A) Fast ocean tides washing sand ashore
B) Tectonic plates colliding over time
C) Strong winds blowing dirt into flat piles
D) Rivers drying up completely
2. What key difference between hills and mountains is mentioned in the text?
A) Hills are smaller with gentler slopes
B) Hills are always covered with glaciers
C) Mountains are flat and ideal for corn
D) Hills only form beneath deep oceans
3. Which natural forces carve valleys between mountains and hills?
A) Underground plant roots
B) Rushing rivers and moving glaciers
C) Volcanic lava cooling on beaches
D) Large herds of grazing wild animals
4. Why do plains often support thriving agriculture and farming?
A) Steep cliffs protect crops from sunlight
B) The land contains glaciers year-round
C) Deposited sediment creates fertile soil
D) Sharp peaks block all rainstorms

The Science of Valleys
V-Shapes and U-Shapes
A valley is an elongated lowland between hills, mountains, or plateaus. While they appear calm today, valleys are evidence of relentless natural erosion. Fast-flowing mountain streams carry gravel and sediment that scrape against rocky ground like coarse sandpaper. Over countless centuries, this river erosion carves out steep, narrow walls, creating a classic V-shaped valley . When a river cuts exceptionally deep with nearly vertical walls, it forms a dramatic canyon .
Not all valleys are carved by liquid water. During past ice ages, enormous moving rivers of ice called glaciers crept slowly through mountain passes. The sheer weight and friction of these frozen giants scraped away rocky slopes, widening the bottom and straightening the sides into a broad U-shaped valley . Because valleys collect nutrient-rich runoff, valley floors have historically provided humans with fertile land, freshwater, and natural transportation routes.
1. What process causes a rushing river to carve a V-shaped valley?
A) Fast-cooling volcanic lava filling craters
B) Carried sediment scraping rock like sandpaper
C) Powerful tornadoes lifting topsoil away
D) Tree branches growing into cracked stone
2. How do glaciers produce U-shaped valleys instead of V-shaped valleys?
A) Their massive width and weight widen the base
B) They melt into boiling volcanic hot springs
C) They deposit sand dunes along windy coastlines
D) They push tall mountain peaks deep underground
3. What is a canyon, according to the text?
A) A shallow pond located on an open prairie
B) A deep valley with exceptionally steep walls
C) A frozen river that never flows or melts
D) A high mountain peak with eternal snow
4. Why have humans historically settled in valley bottoms?

How Mountains Rise and Survive
Tectonic Collisions & Alpine Climates
Mountains are landforms that rise dramatically above their surroundings, typically featuring steep slopes and a pointed summit or peak . Most of the world’s major mountain ranges formed through collisions between enormous tectonic plates. When continental plates slam together, the immense pressure forces rock layers to buckle, bend, and crumple upward into gigantic fold mountains , such as the Himalayas and the Rocky Mountains.
As altitude increases up a mountain, environmental conditions change drastically. Temperatures drop rapidly, winds intensify, and the atmosphere holds less oxygen. Past a certain elevation known as the tree line , conditions become too cold and windy for trees to grow. Above this boundary lies the harsh alpine zone, where specialized animals like snow leopards and mountain goats survive. During spring, melting alpine snowpacks provide vital freshwater that feeds rivers downstream.
1. What happens when continental tectonic plates crash into each other?
A) Flat plains sink into ocean trenches
B) Rock layers buckle upward into fold mountains
C) Entire continents dissolve into liquid water
D) Rivers reverse direction and freeze solid
2. How does the climate change as you climb higher up a mountain slope?
A) Temperatures drop and winds intensify
B) The air becomes humid, calm, and hot
C) Soil becomes deeper and swampy
D) Sunlight disappears completely
3. What is the “tree line” described in the reading passage?
A) A stone fence built to keep wildlife safe
B) The elevation where it is too cold for trees
C) A row of apple orchards planted in valleys
D) The deepest underground layer of tree roots
4. Why are alpine snowpacks crucial for valleys and communities downstream?
A) They reflect heat to cause volcanic eruptions
B) Melting snow feeds rivers with freshwater
C) They prevent rocks from rolling down cliffs
D) They push clouds into outer space

Read the passage about Earth's great plains and prairies, then complete the questions below. Lexile: 640L
Grasslands and Flat Horizons
Coastal and Interior Plains
A plain is a broad expanse of flat or gently undulating land with very little change in elevation. Geologists classify plains into two primary categories. Coastal plains stretch along ocean shorelines, where waves and tides deposit sand and marine silt. In contrast, interior plains lie deep inland, formed across ancient sea floors and river basins where rivers deposited thick layers of nutrient-rich sediment over millions of years.
In North America, the vast interior plain is known as the Great Plains. This region was once covered in wild prairie grasses that sustained millions of bison. Today, these flat terrains serve as productive agricultural “breadbaskets,” yielding immense harvests of wheat, corn, and soybeans. Because plains lack mountains to block gusty weather, winds can sweep across the open horizon, making soil conservation and prairie grass preservation essential.
1. How do interior plains differ from coastal plains?
A) Interior plains lie inland on ancient sea floors
B) Coastal plains are surrounded by high volcanic peaks
C) Interior plains never have any soil or grass
D) Coastal plains are always frozen solid by ice
2. What makes the soil on plains so exceptionally productive for farming?
A) Hard volcanic granite that never erodes
B) Thick layers of deposited nutrient-rich sediment
C) Salt crystals left behind by drying oceans
D) Steep rocky slopes that drain rain rapidly
3. Why are North America’s Great Plains nicknamed “breadbaskets”?
A) Bakers built stone ovens across the grasslands
B) They produce immense harvests of wheat and grain
C) The terrain is shaped like a giant loaf of bread
D) Wild animals store bread underground for winter
4. Why is soil conservation critical on open plains?
A) Without mountains, strong winds can blow dry soil away
B) Ocean tides flood the Great Plains each night
C) Bison herds dig huge underground caverns
D) Falling snow turns the topsoil into bedrock
