Earth Systems

earth's magnetic field extends beyond the atmosphere and affects a region of space called the:

• Magnetosphere

• Mesosphere

• Lithosphere

• Atmosphere

The source of Earth's magnet is believed to be created by liquid ___________.

• Iron

• Nickel

• Carbon

• Aluminum

Recent research indicates that instead of iron, the earth’s magnet could also be generated by ____A____ and ____B____.

• lithosphere, mesosphere

• sun, moon

• inner core, outer core

• atmosphere, hydrosphere

Studying the earth's interior is tricky because scientists are not able to take samples in most of the interior. They have developed models using which of the following technologies to help them create their models?

• Gravitational magnets

• Richter scales

• Seismic waves

• There currently isn't a reliable method for this application

The geosphere is

• the mostly solid, rocky part of the Earth

• all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds

• the regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.

• the mixture of gases that surrounds the earth

Define Plasticity as it relates to the earth's asthenosphere.

• The ability to flow

• Instability in the crust

• Stability even if an earthquake occurs

Select the analogy that best resembles the reason why clouds are a part of the hydrosphere and not the atmosphere? Select all that apply

• Water in lakes and oceans are not part of the mesosphere even though they are located on the face of the earth.

• Rocks in gorges, craters and mountains erode over time causing a change in the geosphere even though they are a part of the lithosphere.

• Fish, plants, and plankton in the ocean are part of the biosphere even though they are located in the hydrosphere.

The biosphere includes plants, animals, and other organisms that live

• on land

• on land and in the water

• on land, in water, and in the air

• in water

True or false. Traveling to the moon will cause your mass to decrease.

• TRUE

• FALSE

Which of the follow ZONES OF THE EARTH creates Earth's magnetic field?

• Asthenosphere

• Mantel

• Crust

• Inner Core

• Outer Core
