What is weathering?
The temperature of the air.
The act of sharing the weather forecast.
The changing of the Earth's surface through chemical or physical processes.
What is physical weathering?
The breaking down of rocks by physical and chemical processes.
When weather causes physical changes to the Earth's surface, such as in the example of breaking larger rocks into smaller ones.
When weather, temperature, pressure, plant and animal actions, and wind, water and gravity cause chages to the Earth's surface.
When reactions to oxygen, acid precipitation, and acids in groundwater or in living things break down the Earth's surface.
What is chemical weathering?
When reactions to oxygen or acids cause changes to the Earth's surface.
When weather causes larger landforms to breakdown into smaller ones, such as when when a larger rock is broken down into a smaller one.
When the wind, rain and gravity causes changes to the Earth's surface.
This is showing an example of______________________.
physical weathering
chemical weathering
acid precipitation
erosion
Oxidation is_____________________________.
an example of chemical weathering
when oxygen reacts with compounds in rocks, causing a reaction
when the oxygen in the air mixes with precipitation
What causes acid precipitation?
When acids in the air combine with water in the air, and the combined chemicals fall as rain or snow.
When the oxigen in the air combines with the water in the air, and then falls to the ground as rain or snow.
When the acid in groundwater evaporates into the air, and falls to the ground as rain or snow.
The following are agents of physical weathering:
acid precipitation and acid in ground water
oxidation
animal action and plant action
wind, water and gravity
temperature and pressure changes
How do animals cause changes to the Earth's surface?
They dig in the ground, moving soil and small rocks.
They move dirt on their feet as they walk around.
They expose rock when they dig.
They cause abrasions and erosion on the rocks they dig up.
A rise and fall in temperature over and over causes __________________ in rocks.
a chemical change
erosion
abrasion
deposition
a physical change
How do plants cause physical changes to the Earth's surface?
The roots cause pressure on exposed rock, breaking it apart.
The weight of the plant, such as a big tree, puts pressure on the rocks.
The water from the plants has chemicals in them, causing the rock to erode.
How does wind, water and gravity change the Earth's surface?
The wind blows rocks around.
Water causes rocks to move.
Gravity moves rocks.
They cause abrasion to occur, breaking rock down.
___________in the Earth causes rocks to become exposed.
Water
Wind
Pressure
Gravity
What happened to the land in the after picture?
Abrasion occurred
Weathering occured
Erosion occured
Oxidation occurred
Abrasion is________________.
how sediment and other objects move from one place to another.
the process of sediment or other objects being dropped after it is moved.
when somethingrough and hard brushes over another object causing it to break down.
Erosion is________________________.
when one hard object rubs against another, causing it to break down.
when objects are moved from one place or another.
when objects that are moved by erosion are dropped in a new place.
What weathering process plays a role in the creation of streams?
Abrasion
Erosion
Deposition
How are canyons and valleys formed?
Abrasion
Erosion
Deposition
Floodplains are formed_______________.
when streams flood.
when streams flood and create valleys.
when streams flood and the sediment is moved and divided.
by erosion and deposition.
How did this occur?
Abrasion
Erosion
Deposition
The following lyrics are from a song sung by_______
I'm jealous of the rain
That falls upon your skin
It's closer than my hands have been
I'm jealous of the rain
I'm jealous of the wind
That ripples through your clothes
It's closer than your shadow
Oh, I'm jealous of the wind
