Matter & Energy in the Earth System

The main effect of negative feedback is...

• It speeds up or enhances a process
• It causes a process to stop entirely
• It causes a process to slow down or reverse
• It has no effect on the process

The hydrosphere includes...

• All living organisms
• Only water in the oceans
• All Earth's water, including water in the atmosphere
• Only glaciers and ice caps

A system is:

• A group of individual parts that work separately
• A group of parts that work together
• A single, isolated part
• A random collection of objects

The system of Earth involves flows that...

• Only energy through different components
• Only matter through different components
• Only gases through the atmosphere
• Matter and energy through different components

What is the water cycle?

• Water evaporates from bodies of water, then rains and flows back to bodies of water
• Water remains in one place, continuously cycling between the ocean and atmosphere
• Water only evaporates and never rains
• Water flows only from land to ocean without evaporation

This is the energy that is required so water evaporation may happen, which is it?

• Electrical energy
• Mechanical energy
• Heat energy from the Sun or Earth's interior
• Chemical energy

Which describes the subsystem "atmosphere"?

• It is a thin envelope of gases, including air and dust particles
• It is the Earth's solid inner core
• It is composed entirely of water
• It contains only the Earth's ice and snow

Which subsystem includes all the rock and metal?

• Atmosphere
• Hydrosphere
• Biosphere
• Geosphere

The Cryosphere consist of...

• All of Earth's water
• Only the Earth's atmosphere
• The frozen part of the hydrosphere, including all ice and snow
• All the living organisms on Earth

The biosphere has...

• Only the solid rock of Earth
• All living organisms on Earth
• Only Earth's water
• Only gases in Earth's atmosphere
