Landforms: Review
What is a physical feature on Earth's surface called?
Landform
All landforms are created and changed by some type of ______.
a. force
b. tsunami
c. wind
d. water
a. force
Why don’t very many people choose to live in the desert?
It’s hot and extremely dry; these factors make the soil infertile for growing food!
What is the main difference between mountains and plateaus?
Mountains typically have pointed tops, whereas plateaus have flat tops.
What is formed at the mouth of a river?
Delta
Tectonic Plates
Explain why many people choose to live in the plains. Hint: What do the plains have that could make life easier for people?
The flat land makes it very easy for us to farm as well as travel.
Which landform might you find between two mountains or hills? Hint: Erosion contributes to the creation of this landform!
Valleys
We live in the plains! This landform is generally a large area of flat land that does not change very much in elevation.
As lava and ash continues to erupt out of a volcano, the volcano will get __________ over time. Why is this?
a. shorter and shorter
b. flatter and flatter
c. taller and taller
c. taller and taller
Many people either live in or travel to which type of landform for rock climbing and hiking?
Mountains
The features on Earth’s surface usually change very slowly over a long period of time, but some features can change in a very quickly short period of time. What would be an example of how a landform can change in a short amount of time?
Volcanic eruptions, landslides, earthquakes
This is a special type of mountain that has an opening a the top where lava and ash comes bursting out.
Volcano
When weathering breaks down rocks and soils in landforms and erosion picks up and carries away these broken down particles, what happens next?
The broken rock and soil particles get dropped off in a completely new location, sometimes making a new landform! This is called deposition.
How can people contribute to, or help cause erosion?
When we build new roads, houses, business, etc., we dig into the earth. This causes the land to move around and can end up causing erosion, which can result in landslides, falling rocks, and many other dangerous effects!
The features on Earth’s surface are known to change very slowly over a long period of time. What would be an example of how a landform can change in a long period of time?
Wind, water, changing temperatures, living things (aka weathering)
Plains and plateaus are both known to be flat landforms. Can you explain the difference between these two landforms?
Plateaus are flat areas of land that are more elevated, or higher up, than plains are.
Many landforms are created through the process of erosion, or the carrying away of weathered rocks. Name two natural factors that could possibly carry away weathered rocks through erosion.
Rivers or any sort of moving water, wind, gravity, and even activities that people do
What can people do to help slow down erosion and the changing of landforms?
We can take care of our planet! We can start by being more cautious of how we make use of the land around us. Cutting down a lot of trees exposes the healthy soil to water and wind, which are the main contributors of erosion. A very easy thing to do is plant plants as this will help keep the soil compact, healthy, and less likely to endure erosion.
What are the three tectonic plate boundaries? Which boundary would we have when mountains and hills are formed?
Convergent- this is where the plates move into one another
Divergent- this is where the plates move apart
Transform- this is where the plates move side by side
