It cuz yer close to a large body of water! Duh.
I lived in the Try-Valley (Ptown/Livermore) and commuted to to Santa Clara for over 15
yrs. It was always 10 degrees hotter, "over the hill" (Fremont Grade), than in the
The "marine layer" comes in, at night, and cools everything.
UNLESS! ....there's a "high pressure" center over the SFBA. Then, the
prevailing winds all move from onshore to offshore, giving us those
dreaded "hot spells".
I usta have a link to a SFBA wind map, but it appears that has been
shut down. OTOH, I no longer suffer from these problems cuz I moved
to the CO Rockies. :)
It depends on _which_ hills you're up on, and on the current
marine layer height. If you're up off quimby or mt hamilton
road, it's likely warmer in the summer than downtown. On
the coast range side, it varies, but consider that Los Gatos
is frequently 5 to 10 degrees warmer than downtown SJC.

If you can explain why it's cooler in the summer (even though I get about 4
more hours of sunlight than does San Jose, from about 6am to about 10am)
and warmer in the winter (my BMW dings when I get down to the bottom and I
can see frost on the grass on the bottom - where it's ten degrees colder).
Part of it must be due to having no shadow whatsoever (sun I have plenty
of), but some of it must be due to the height and to the wind factors.
As for the geology of the soil, I don't want to pinpoint my exact location
on the Internet (who knows what cuckoos lurk herein), but, suffice to say
that anyone who knows the local geology can pinpoint me just as well as
they pinpointed Osama Bin Laden from the Tora Bora background pictures.
Here's a picture I snapped today of the roadcut on my land:
Notice that the "soil" is Franciscan "ribbon chert" for a thousand or more
That's what I'm dealing with.
could be pollination or temperature or a
mutation/hybrid which isn't very self-fertile.
some days when it's really hot i'll water the
whole plant to make sure the flowers get dinged

All numbers. Very dry stuff.
But, I did take elective classes in college, one of which was a geology 101
But, in geology, they cover plate tectonics and volcanoes and earthquake
Not the NPK, pH, and humus of soil samples.

The way it works, technically, is that Rock is the big stuff that weathers

Once you displace that soil, then it becomes dirt.
So, dirt is merely soil that is not in situ anymore.
There's an entire concurrent thread on this distinction over here:
The thread it titled:
Dirt is now soil; rock is not stone
Sort of. The size - NOT composition - of the weathered rock determines its
Colloquially, the last three would be "mud". I would characterize what you
have as coarse soil.
The fact that composition does not enter into it means that "sand" can be
ANY mineral, not just quartz.
If you want to get a better idea of the size ratio in what you have, put
some of it in a glass jar, add 4-5 times as much water, stit it up and let
it settle for a couple of days. The "rocks" and sand will be fairly
obvious. If you want to get an idea of the silt - top layer - use a pipette
or turkey baster to suck up a bit from the top layer and see how it feels
between your teeth. Pretty gritty=coarse silt, gritty but not all that
much=medium silt, barely gritty=fine silt.
That's a great description. I don't disagree that it's "course soil".
At this point, since it's displaced, it's "course dirt".
I look at sand all the time under the microsope just for fun. The quartz is
the light white stuff but there's darker reddish stuff and black stuff too.
Nice test! Stokes law.
I already have a Costco peaches jar ready to settle the issue once and for
Interestingly, there was a cloud of dust that the picture doesn't capture,

Different meanings for different sciences. It pays also to consider
that word usage is sort of like dictionary definitions. Both describe
how words are being used and not necessarily how they *should* be used.
I would say that you would start with minerals and when several
minerals are mixed together into a solid chunk it is rock no matter the
size. Stone can be removed from a rock quarry and seems to imply that
stone is serving some useful purpose as building material for instance.
River rocks are often used in decorative building material, but it
doesn't mean that they cease being rock just because they are used like
I had heard that there is a progression from sands (clay, silt, sand)
when dead boilogical material is added it is termed 'dirt' and when
living biological material is added it becomes termed as 'soil', but
then again different sciences may make different distinctions.
I was more referring to inorganic, organic(dead), organic(living), but
yes there is a rock cycle of sorts. Even including minerals used by
organisms falling to the ocean floor when they die and eventually
becoming limestone. Nothing exists in a vacuum.
