Geography Chapter 2 Terms

The hydrosphere is:

• The hydrosphere is the atmosphere surrounding Earth.
• The hydrosphere is the solid part of Earth.
• The hydrosphere is the water areas of the Earth.

• The hydrosphere is the layer of gases around Earth.

Answer explanation

This includes oceans, lakes, rivers, and other bodies of water.

The lithosphere is:

• The uppermost layer of the Earth, including the crust.

• The molten layer of the Earth beneath the crust.
• The gaseous layer surrounding the Earth.
• The liquid outer core of the Earth.

Answer explanation

This layer contains the Earth's land, which includes the crust, continents, and ocean basins(the land beneath the oceans).

The atmosphere is:

• The thin layer of gases surrounding the Earth.

• A type of weather phenomenon.
• A solid layer beneath the Earth's surface.
• A collection of stars in the universe.

Answer explanation

Our atmosphere is 78% nitrogen, 21% oxygen, and the rest is argon and other gasses.

The biosphere is:

• The biosphere is the part of the Earth where life exists.

• The biosphere is a layer of the atmosphere.
• The biosphere is the study of plant life.
• The biosphere is a type of geological formation.

Answer explanation

All people, animals, and plants live on or close to the Earth's surface or the atmosphere.

Within geography, a sphere is:

• A flat surface with no curvature.
• A two-dimensional shape with varying distances from a center point.
• A polygon with equal-length sides.
• A three-dimensional round shape where all points on the surface are equidistant from the center.

Answer explanation

There are 8 planets in the solar system that we know about. (sorry Pluto! You are now classified as a dwarf planet)

There are 4 known planets in our solar system with rocky crusts. Another name for them is:

• Gas giants
• Ice giants
• Dwarf planets
• Terrestrial planets

There are 4 known planets in our solar system composed of something other than a rocky crust. They are called:

• Earth, Mars, Venus, Mercury
• Gas Giants

• Terrestrial Planets

• Jupiter, Saturn, Uranus, Neptune

Answer explanation

Jupiter, Saturn, Neptune, and Uranus are gas giants, less dense and MUCH larger in diameter than the terrestrial planets in our solar system.

A scientific theory can be defined as:

• A random guess about the universe.
• A personal belief without evidence.
• A plausible general principle offered to explain observed facts.

• A hypothesis that has not been tested.

The 4 parts of the atmosphere are:

• troposphere, stratosphere, mesosphere, thermosphere
• stratosphere, thermosphere, atmosphere, exosphere
• troposphere, stratosphere, hydrosphere, lithosphere
• exosphere, ionosphere, magnetosphere, biosphere

Within geography, the coastal plain is:

• A flat, low-lying area adjacent to a coastline.
• A tropical rainforest located inland.
• A desert area with no water bodies.
• A mountainous region far from the coast.
