Earthquakes
Earthquakes can happen along any type
of plate boundary. They also occur along faults which are large cracks
in the earth’s crust. Most faults are associated with large plate
boundaries where violent earthquakes usually occur.
Causes of Earthquakes
- Earthquakes are caused when the tension is released from inside the crust.
- This happens because plates do not move smoothly - sometimes they get stuck.
- When this happens a great deal of pressure builds up.
- Eventually this pressure is released and an earthquake tends to occur.
An earthquake starts deep below the earth’s surface at the focus.
The focus is the point inside the Earth's crust where the pressure is released.
The epicentre of an earthquake is the position on the earth’s surface directly above its focus.
The jerking movement caused by plates sticking then moving releases built-up pressure inside the Earth's crust, in the form of seismic waves. The waves spread out from the focus.
The strongest waves are found near the centre of the earthquake. This
means that the most severe damage caused by an earthquake will happen
close to the epicentre.
It is almost impossible to predict when they will occur. The effect
of an earthquake depends on the depth of an earthquake as well as its magnitude.
Dear 4th and 5th Grade Families,
The Green Team is about to
start up again for this school year. Our Green Team last year was
responsible for completing the Sustainability Challenge in partnership
with Clean Memphis last year! They started a recycling
campaign and conducted energy audits. After the energy audits, students
gave the teachers ideas on ways to conserve energy, and we were able to
save money and energy with these efforts.
This year, we are aiming to
go for gold with the Sustainability Challenge! This entails the Green
Team students being active participants and advocates in making Campus
School as eco-friendly as possible. Our focus
this year will continue to be recycling and energy conservation.
However, we are also going to focus on water and air quality. There is
no cost to participate in Green Team.
Our club will meet on Mondays
this year in Ms. Caldwell's room (Room #103) from 3:00-4:00 or 4:15. We
will NOT meet every Monday. We will meet as events/projects are coming
up. (Communication for meetings will be via
email and always located on Ms. Caldwell's blog.) We realized other
after school activities meet on Mondays; however, this was the only
day that the teacher organizers could meet due to other school-related
obligations.
Our first Green Team meeting
will be Monday, November 30 in Ms. Caldwell's room. We will meet after
school until 4:15. All pick up will be at half circle drive.
If your child is interested, please fill out all of the information on this Google Form by Tuesday, November 17:
If your child is interested,
but cannot attend this first meeting, please still sign up on the Google
Form above to stay informed of future meetings.
If you have any questions, please email Ms. Caldwell. lprvette@memphis.edu
Thank you,
L. Caldwell, L. Faulkner, G. Hillhouse, J. Hughes, and L. Virden
