Environmental Science chapter 3 test study guide
Terms in this set (52)
The solid part of the Earth that consists of all rock, as well as the soils and loose rocks on Earth's surface.
Earth's thin outer layer
Layer beneath the crust
Earth's innermost layer
Earth's outer layer
Layer beneath the lithosphere
Divided the lithosphere into pieces. These pieces glide across the underlying asthenosphere.
The removal and transport of surface material
Earth is surrounded by a mixture of gases
Atmospheric layer nearest Earth's surface
Above the stratosphere.
Absorbs the sun's ultraviolet energy and warms the air. Ozone is a molecule made of three oxygen atoms
transfer of energy across space and in the atmosphere
the flow of heat from a warmer object to a cooler object
the transfer of heat by air currents
the process when gases trap heat near the Earth. Without the greenhouse effect, the Earth would be too cold to function.
the continuous movement of water into air, onto land, and then back to water sources
the process by which liquid water is heated by the sun and rises into the atmosphere as water vapor.
Water vapor forms water droplets
Larger droplets fall from the clouds as rain
salt content in water
A little more than 3 percent of the Earth is ______
A layer othe the Earth's atmoshpere where life can exists.
How does convection ovens work?
They help bake or roast your food faster by using a fan to get the heat circulated more quickly and evenly.
where is the ozone located?
In the stratosphere
The Main cause of Earth quakes
Tectonic plates moving
The effects that a large- scale volcanic eruption can have on the global climate
A drop in the average global surface temperature
The wind and water alter the Earth's surface by
process of erosion
The surface of the Earth would be different if it were not divided into tectonic plates
1. Earth's surface being smooth (But still affected by erosion, glaciers, etc. )
2. Less diversity in Plants and Animals
The Physical features of a young mountain range and an old mountain range
young mountain range-sharp peeks, steep slopes, deep valleys, swift- running rivers
old mountain range- Rounded peaks, less steep slopes, broader valleys , slower running rivers
Physical layers of the Earth
Asthenosphere-made of rocks that flow very slowly
Mesosphere- Middle Sphere
Outer Core- Liquid nickel and iron
Inner core- Solid nickel and iron
Compositional Layers of the Earth
Crust-We live on it
Core-Very Hot and Very high pressured
All water have salt contents except distilled? T/F
The Earth's atmosphere is composed mainly of _____ nitrogen and _____ oxygen and _____ small quantities of other gases
78%, 21%, 1%
Characteristic of the atmospheres
Thermosphere: northern lights
The three mechanisms of heat transfers
Radiation, Conduction, and convection
Role of greenhouse gasses
To absorb energy and radiate much of it back towards the surface to heat up the earth
Earths atmosphere becomes less dense w/ increasing altitude above Earth
gravity pulls most of the atmosphere's gas molecules closer the Earth's surface.
Human- activity change some greenhouse gas levels
By humans burning fossil fuels which releases CO2 into the air and that adds the greenhouses gases.
The thin layer at the Earth's surface where life exists is called_____
The thin layer of the Earth upon which tectonic plates move around is called the
Seventy-eight percent of the Earth's atmosphere is made up of ____
The ozone layer is located in the _______
Convection is defined as the _____
transfer of heat by currents
Which of the following gases is a green-house gas>
water vapor, methane, carbon dioxide
Liquid water turns into gaseous water vapor in a process called______
Currents at the surface of the ocean are moved mostly by_____
Which of the following statements about the biosphere is not true?
Matter is constantly added to the biosphere
How do seismic waves give scientists information about the Earth's interior?
Deflection of the seismic waves
Explain the effect of gravity on Earth's atmosphere
Gravity pulls gasses down
Explain how convection currents transport heat in the atmosphere
Hot air rises and cool air goes down
Why does land that is near the ocean change temperature less rapidly that land that is located farther inland?
Harder to heat and cool down water, water absorbs heat slower than land.
