Sunday

I love sunday!
coz it's the only day
that i can say yeah!
and it makes me happy.

thank god it's sunday
God, this is your day
the day of love
and peace shown by a dove

it's a sunny day
and it's warm due to sun's ray
the sky is blue
good for me and you

i hear the birds' tweets
and it sound so sweet
i feel the wind's whisper
on my two little ears

the trees are swaying
it seems that they are dancing
the flowers bloom
as i saw it from my room

this why i love sunday
coz i can say hurray!
i am so happy
for it is sunday

ROCKS

Rock is an aggregate of minerals
It may contain metals and non-metals
there are many types of it
So prepare your identification kit

Let us begin with igneous
It forms when magma cools
Basalt is volcanic and mafic
While Granite is plutonic and felsic.

Rhyolite is also volcanic but felsic
While Gabbro is plutonic but mafic
Andesite is intermediate but volcanic
While Diorite is intermediate but plutonic

Another type is sedimentary
Which is important in paleontology
For they contain fossils
buried for many years

Shales and Sanstones are clastic,
While Limestones and Dolostones are non-clastic
they form after rock's erosion
and then deposition,compaction, and cementation

What happens when rock is subjected to pressure?
Or maybe on great temperature?
Is it changed and minerals became elongated?
Oh it becomes metamorphic!

Have you heard about gneiss?
Yes it is really nice!
How about slate, phyllite, schist, and marble?
they are all adorable!

Geology rocks!
Because they study rocks!
