Dynamic Earth

How are global winds created?

Unequal heating of Earth's surface over large areas

Why is the Ozone layer important to Earth?

protects us from the UV radiation from the sun

What process absorbs energy from the sun and hold heat close to Earth?

greenhouse effect

In which layer of the atmosphere does the weather happen?

troposphere

In which layer of the atmosphere do the meteors burn up?

mesosphere

In what layer of the atmosphere would you find the Ozone? 

stratosphere

 In what layer of the atmosphere would you see the Aurora Borealis?

thermosphere

What are the two types of crust?

continental and oceanic

Mountains form from ...

collision of plates

The place where two plates come together is known as a

convergent boundrary

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as

subduction

What is the correct order (starting from the surface) of Earth’s layers?

crust, mantle, outer core, inner core

One of the most important functions of the world ocean is to

help regulate earths temperature

The layer of the ocean that has a sharp decline in temperature as you increase in depth

thermocline

The layer of the ocean that receives the most direct sunlight

surface zone

The layer of the ocean that receives no direct sunlight

deep zone

The measure of the amount of dissolved salts in a given amount of liquid

salinity

All the water on earth can be found i

hydrosphere

Streams that flow into other streams increasing the size of the stream that it is joining 

tributaries

a winding curve or bend in a river

meander

The height and number of waterfalls along a stream or river depends upon the type of 

rock

What section of the river do we see an increase in lateral erosion and meanders and Oxbow lake formation? 

middle

The channel of a river is usually widest and deepest at what point? 

lower section

Does the middle course of the river have more water or less water than the upper course? 

more

As a river gets closer to the sea its height

decreases

What is an area of land drained by a river and its tributaries? 

river basin

The continuous transfer of water between the sea, the land, and the atmosphere is known as the 

the water cycle

Without the greenhouse effect, the Earth would be too cold for life to exist.

True

Ozone is composed of three 

oxygen atmos

The layer of the atmosphere where the ozone layer exist

stratosphere

The level of the atmosphere where weather conditions exist 

troposphere

As you increase in altitude in the troposphere the temperature

decreases

As you increase in altitude in the stratosphere the temperature

increases

As you increase in altitude in the mesosphere the temperatur

decreases

As you increase in altitude in the thermosphere the temperature

increase

As you get closer to earth the air pressure 

increases

The solid, plastic like layer of the mantle

asthenosphere

The lithosphere is divided into huge pieces called

tectonic plates

the solid outer layer of the earth

lithosphere

The lower part of the mantle

mesophere

Mostly made of solid iron and nickel

inner core

the core that is a dense liquid layer

outer core

How do scientists learn about the earth's interior? 

seismic waves

Both Earth's water and atmosphere depends on what to exist? 

Earth's magnetic field

The core of the Earth is mostly made of?

Nickel and Iron

What drives the movement of the tectonic plates? 

flow of the rock in the mantel

Earth's magnetic field is produced by 

the liquid iron convecting in the outer core

Earth's magnetic field protects us from 

the Sun's solar winds

Which gas makes up approximately 78% of the Earths Atmosphere?

Nitrogen
