Matter is defined as everything that has a place in space. All matter has two general properties - mass and volume. Mass is the quantity of matter and can be measured with a scale or balance in kilograms. Volume is the space a body occupies and can be measured with a graduated container in litres. Specific properties of matter include flexibility, fragility, resistance, rigidity, and whether something conducts or does not conduct heat.
The document summarizes key concepts in geology including the tectonic and hydrologic systems that shape the Earth's surface. It describes plate tectonics and mantle convection that drive the tectonic system, and the water and atmospheric processes that drive the hydrologic system through weathering and erosion. It also compares the geological features and evolution of the terrestrial planets and moons based on differences in size, composition and distance from the Sun.
This document provides an overview of plate tectonic theory and the evidence that supports it. It discusses early ideas including continental drift theory and how the development of seafloor spreading theory addressed continental drift's lack of a driving mechanism. It then summarizes key evidence for seafloor spreading including the global system of mid-ocean ridges, patterns of magnetic reversals in ocean crust, and the age progression of ocean floors. This led to the modern theory of plate tectonics unifying continental drift and seafloor spreading.
This document provides an introduction to natural disasters. It defines natural disasters as naturally occurring hazards including geophysical, hydrological, climatological, meteorological and biological events. Examples are given of each type.

The Earth is divided into four main layers - the crust, mantle, outer core, and inner core. The crust is the thin outer skin of the Earth, making up only 1% of its volume. Below the crust lies the mantle, which is the largest layer and divided into upper and lower sections. Within the Earth is the core, with the outer core being liquid iron and the inner core being incredibly hot solid metals.
The document summarizes the four main layers of the Earth - the crust, mantle, outer core, and inner core. The crust is very thin compared to the other layers and makes up only 1% of the Earth. The mantle is the largest layer and is divided into upper and lower sections. The outer core is liquid and made of iron, while the inner core is a solid ball of extremely hot metals.

The document discusses the structure of the Earth and compares it to a hard boiled egg. It explains that the Earth has four main layers - the crust, mantle, outer core, and inner core. The crust is the solid outer layer made of rocky plates, the mantle is below the crust and made of molten rock, the outer core is very hot molten metal, and the inner core is solid metal. Cutting open a hard boiled egg reveals similarities to the Earth's layered structure.
The document discusses the three main layers that make up the Earth - the crust, mantle, and core. The crust is the topmost layer and is broken into tectonic plates that move along the mantle, sometimes getting stuck and causing earthquakes. The mantle is the largest layer and is made of hot, dense rock that flows and causes plate movement. At the center is the core, which is composed of a solid inner core surrounded by a liquid outer core made of hot metals.
This document provides information about investigating soil, including standards, objectives, materials, and procedures for a lesson on soil layers. The lesson teaches students about the different components and layers of soil through hands-on exploration. Students bring in soil samples from their yards and observe the samples separate into distinct layers over time when mixed with water. This illustrates how soil forms horizontally layered horizons from the organic-rich upper layers to the underlying rocky layers. Students learn to identify and label the four major soil layers - humus, topsoil, subsoil, and bedrock.
The Earth is divided into four main layers - the crust, mantle, outer core, and inner core. The crust is the outermost layer and makes up only 1% of the Earth. Below the crust lies the mantle, which is the largest layer and consists of the upper and lower mantle. At the center are the inner and outer core, with the outer core being liquid iron that generates the Earth's magnetic field and the inner core being solid iron.

The crust is the thin solid outer layer that life exists on. Below is the mantle, which is hot and flows over geological timescales. At the center are the outer core, made of liquid nickel and iron, and inner solid core, where temperatures and pressures are extreme.
Social networking sites allow people with common interests to interact and share information through features like messaging and video chatting. While information is typically public, privacy settings allow profiles to be hidden. Some of the earliest popular social media sites were Classmates.com in 1995 and SixDegrees.com in 1997. Today the largest sites are Facebook, with 85% of US college students as members, MySpace with over 80 million profiles, and Friendster, one of the first to gain popularity.
Photodiodes are semiconductor devices that convert light into an electrical current. They operate using the photoelectric effect where photons are absorbed, generating electron-hole pairs that result in a photocurrent. There are different types of photodiodes including PIN, PN, avalanche, and Schottky structures. Photodiode technology has evolved from developments in PN junction diodes in the 1940s and 1950s, with the PIN photodiode developed in 1959. Materials used include silicon and germanium.
The 802.11 standard defines specifications for wireless connectivity in local areas. Its goal is to develop MAC and PHY specifications for fixed, portable, and mobile wireless connections. It has had several amendments that specify standards for different PHY layers, frequencies, security protocols, and QoS capabilities. Devices using the 802.11 standard do not require a license to operate in the 2.4GHz and 5GHz public frequency bands defined by the standard.

2. Earth Layers
• The Earth is divided into four main
layers.
*Inner Core
*Outer Core
*Mantle
*Crust
3. The Crust
* The Earth’s crust is like
the skin of an apple. It
is very thin compared to
the other three layers.
*The crust makes up 1% of
the Earth.
* The crust of the Earth
is broken into many
pieces called plates.
4. The Mantle
• The mantle is the
layer below the
crust.
• The mantle is the
largest layer of the
Earth.
• The mantle is
divided into two
regions: the upper
and lower sections.
5. Outer Core
* The core of the
Earth is like a ball
of very hot metals.
* The outer core is
liquid.
* The outer core is
made up of iron and
is very dense.
6. Inner Core
* The inner core of
the Earth has
temperatures and
pressures so great
that the metals are
squeezed together
and are not able to
move.
* The inner core is a
solid.
7. The Earth Bowl
• First, everyone will divide up into groups!
• The groups need to pick two people to be the
materials specialists. Those people will need to get:
A plastic baggie which contains
graham crackers and sugar.
A container of raspberry Jell-O
A container of black cherry Jell-O
A container of lemon Jell-O
A spoon
A bowl
DO NOT TOUCH ANY OF THE MATERIALS AFTER
YOU HAVE RECEIVED THEM. WAIT UNTIL I
EXPLAIN WHAT TO DO.
8. The Steps to Making the Layers!
1) First you will need the plastic baggie containing
graham crackers and sugar. Break the graham
crackers up with the sugar in the bag.
DO NOT POUND TOO HARD! YOU DON’T WANT
THE BAG TO BREAK!
2) After the graham crackers are broken up into
crumbs, I will bring you butter to mix in the
baggie.
3) Now, take the graham crackers out and press
the mixture on the sides of the bowl to form the
crust.
9. 4) Now take the black cherry Jell-O and
spoon it into the bowl that you have put
the crust in. Form it so there is a pocket in
the middle left open.
5) Take the lemon Jell-O and put it in the
bowl where you left the pocket, but make
sure you leave a hole in the middle for
your raspberry Jell-O.
6) Finally, put your raspberry Jell-O in the
center.
10. You have now made the
Layers of the Earth.
*The Crust (graham crackers)
*The Mantle (black cherry)
* The Outer Core (lemon)
* The Inner Core (raspberry)
11. Review
1) What are the four layers of the Earth?
2) The Earth’s crust is very ______?
3) The mantle is the largest layer of the
