Landforms
Loose sand piled by steady wind forms what hill-like feature?
Sand dune
Breaking rocks into smaller pieces is called what?
Weathering
How are SAND DUNES formed?
Wind blows loose sand and drops it where the wind slows. making sand dunes.
What do we call the conditions like temperature and rain for just one day?
Weather
Today it is sunny and 75°F — is this describing weather or climate?
Weather
A deep valley carved by flowing water over time is caused by what process?
Erosion by a river
Moving rocks and soil from one place to another is called what?
Erosion
how does a GLACIER changes a valley’s shape ("U" should know).
A glacier scrapes the land and makes the valley wider and U-shaped.
What do we call the usual kind of weather a place has over many years?
Climate
This place usually has snowy winters each year — is this weather or climate?
Climate
Sediment that builds up where a river slows down and meets the ocean forms what?
Delta
When carried sediment is dropped and builds up, that is called what?
Deposition
Give one simple difference between weathering and erosion.
Weathering breaks rock in place; erosion moves the broken pieces.
Give one short example of a weather event and one example of a climate fact.
Weather: "A thunderstorm today." Climate: "This place has hot summers."
Which would be an example of a short-term warning: "Bring an umbrella today" or "Winters are getting less cold over decades"?
"Bring an umbrella today"
A U-shaped valley was most likely formed by which icy mover?
Glacier
Give me 2 examples of DEPOSITION.
Sand dunes and Deltas
How do DELTAS form?
Rivers slow down and drop sediments at the mouth of the river where the river meets the ocean. Sediments build up making a DELTA.
Which tells more about long-term patterns: one rainy day or many rainy seasons over years?
Many rainy seasons over years
Give a short sentence someone might say about today, and another they might say about the place’s usual seasons.
"It is windy today." Usual seasons: "Spring is often rainy here."
Name two natural agents that can make rock arches.
Wind and water
Put these in order for what happens to rock: it breaks down, is carried away, then settles.
Weathering → Erosion → Deposition
What happens to rocks as a river carries them from the mountains toward the sea?
They get smaller and smoother
Give one way people might use climate information (one short reason).
To plan farming, buildings, or what clothes/activities are usual
Name one change people might notice if a location’s climate becomes drier over many years.
Plants that need lots of water may die or be replaced by dry-tolerant plants
