Rocky Home, Roots and Cycle
What is rock?
A collection of minerals
What are types of weathering?
Physical, Biological and Chemical
If you see a full grown tree, what type of soil layer can it reach?
Subsoil
Which is the shortest month?
February
Magma, granite, and basalt are all what type of rock?
Igneous!
Why is rain slightly acidic?
It dissolves carbon dioxide from the air
What animal has been called: Nature's Plow?
Worms, by Darwin
How tall is Mr. Ruby? In cm or feet/inches
195.8 cm
6 feet 5 inches
How does Sedimentary rock form, and what are three examples of it?
When particles of minerals which were eroded from rock in one place get stuck together again in another place, to form new rock.
Mudstone, Sandstone and Limestone are examples.
Where would rock weather the fastest? What type of climate?
Somewhere which changes from hot to cold, with a lot of rain.
After crops are harvested, soil can be low in nutrients. What can farmers do to solve this problem?
Leave, or add fertilizers
How many Tuesdays, Wednesdays and Thursdays will we have this month?
5 each, so 15!
Why are the Earth's plates constantly moving?
Super hot currents of melted rock slowly drag plates around under the surface of the Earth
What is an example of Biological weathering?
Biological weathering is the weakening and subsequent disintegration of rock by plants, animals and microbes. Growing plant roots can exert stress or pressure on rock.
As limestone dissolves, it often leaves gaps. What are the gaps called?
Grykes
Explain what the King of Thailand did this week
Dumped his consort because she was acting like a Queen... meaning he didn't want another Queen, but he named her his consort two months after marrying his 4th Queen... so why didn't he just make her his 5th Queen??
The sculpture David is made of marble, which is metamorphic rock. Explain the process by which sea shells eventually became David's marble.
In short:
weathering, then erosion, then sediments are compacted to become sedimentary rock which are forced underground where heat/pressure change them to metamorphic rock, then more burying, it melts into magma, which cools into Igneous rock, and as it is gradually raised upwards, we eventually find it.
What is the key difference between chemical and physical weathering?
In physical the rocks do not change.
In chemical, the rocks change
Out of Granite, Limestone and Mudstone:
Which type of stone is best for farming (not of sheep) and why are the other two bad for non-sheep farming?
Mudstone is best for farming because it's full of nutrients that plants need.
Granite and Limestone are good for sheep farming
What environmental disaster is happening to the beautiful island chain in the Indian Ocean called the Maldives?
Sea levels are rising, pushing salt water into the ground water, destroying crops, flooding the land/homes and generally making life miserable/impossible.
