A large naturally occurring community of flora and fauna occupying a major habitat is:
a food chain |
|
a community |
|
a biome |
|
a population |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
The envelope of gases surrounding the planet is called the:
lithosphere |
|
geosphere |
|
atmosphere |
|
hydrosphere |
The biosphere is the global ecological system integrating all living beings and their relationships. This includes their interactions with the lithosphere (the rigid outer part of the earth, consisting of the crust and upper mantle), hydrosphere (all surface water), and atmosphere (the envelope of gases surrounding the planet).
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s2 to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 m/s to a mass of 1 kg |
|
1 mph to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
In the water cycle, infiltration is most closely related to:
oceans |
|
water table |
|
rivers |
|
runoff |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
visible light → ultraviolet light → radio waves |
|
infrared waves → microwaves → ultraviolet light |
|
microwaves → radio waves → visible light |
|
radio waves → visible light → gamma rays |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
