Level 3 Questions:
Do you think weathering is important to our world?
Do any other planets have weathering too?
When Earth was created were there any weathering around?
What were some differences between weathering and erosion?
What were some types of rocks that are caused by weathering?
Why do you think water considered to be the most important cause of weathering?
What are some impact of weathering that can affect peoples (health)?
How does chemical weathering makes it so easy for a rock to be mechanically weathered?
What is weathering?
The process that breaks down rock and other substances at the Earth's surface.
What are the three different types of weathering?
~ Mechanical Weathering
~ Chemical Weathering
~ Biological Weathering
Chemical weathering takes place in almost all types of rocks. It happens when water and oxygen react with minerals in the rocks to produce new minerals. The minerals can be softer and can crumble easily. Chemical weathering can change the molecules that's in the rock. Water and acid (rain can be little acidic, so watch out) can do this thing.
Biological Weathering is a wearing away of rocks by living things. Any growing things can be powerful destructive forces for rocks.
How is weathering different from erosion?
Weathering:
Erosion:
Why do you think water is considered to be the most important cause of weathering?
What are some positive/negative impact of weathering that can affect people?
Positive Impact:
Weathered rocks are used by people to build houses or constructions bridges. Weathered rocks are really useful. Weathering can also create a new land forms which attracts tourists to come and see it.
Weathering is important because without the weathering we would have no soil. If we won't have soil the earth would be just full of rocks and water. And you can't farm any more vegetables which is the only food that we need everyday. Vegetables contain other nutrients such as minerals, water, and fiber. So thanks for the weathering we have soil today.
Do you think weathering is important to our world?
Do any other planets have weathering too?
Probably yes, because some planets like Venus it usually rain acids there, which is dangerous because if the acid touched you skin, your skin would burn like cooking your burned food. Anyway, acid rain can really burn your skin even if you have something to protect your body, because the acid rain can get through your clothing and burn your skin.
The acid rain in Venus never reaches the ground, however the high temperatures evaporate the acid drops, causing them to rise up again into the clouds again.
Negative Impact:
- Mildly acidic rainwater can damage buildings especially building construction that are made out of limestone which they often used.
- Strong winds that carry weathered rock materials and sand to deposit them on farm land.
How does a freezing temperature causes rock weathering?
Ice causes abrasion of rocks which grooves and cracks. The water enters the grooves or the cracks and freezes which can cause the rocks to break open like breaking an egg.
What some types of rocks that are caused by weathering?
What are some causes of weathering?
~ Plants
~ Animals Life
~ Atmosphere
~ Water
~ Snowing
~ Rainy
~ Storming
Mechanical weathering can takes place when rocks are broken apart by a physical forces, like water or wind. Mechanical weathering breaks down rocks into small pieces, but its still the same rock that have been broken down
~Weathering is a process that breaks down rock and other substances at the Earth's surface. There are three types of weathering:
Mechanical
,
Chemical
, and
Biological
. Some external causes of weathering are atmospheric conditions like air, pressure, etc.
~ In the garden/field-- Wind, rain, water from garden hoses, freezing temperature, etc
The process of eroding or being eroded by wind, water, or other natural agents. There are five types of Erosion:
Water
,
Ice
,
Wind
,
Gravity
, and
Thermal
. Some external causes of erosion are wind, water, ice, humans, etc
~In the garden/field weathering breakdown of the top soil which causes the change in the health and growth of plants.
Sedimentary rocks are formed by weathering. Most commons sedimentary rocks are talc, shale, limestone, and a sandstone. Other such as conglomerates and breccia.
Chemical weathering softens the rock which makes it so easy for the mechanical weathering to break it.
I think water is the most important cause of weathering because in addition to abrasion and ice wedging, water is the most necessary of all types of the chemical weathering.
When Earth was created were there any weathering around?
Probably yes, because in very beginning of earth, there were probably weathering around like when it rains acids, or a water went in to crack then freezes there until the rock are broken into big chunks, or a rock that had been broken down by a physical forces like wind or water. Some people didn't know anything about weathering not until someone had discovered it and shared to other people.
