Module 2 - The Nature of Physical Geography
A remote sensing system that uses only natural energy (from the environment) is called:
passive
Positive Feedback is:
A response to a change in a system that reinforces and amplifies more of the same type of change.

Geographers use direction and distance to define relative location, that is, the position of one place with reference to another.
Complete the paragraph below by dragging the correct word or phrase to fill in the blank.
Humanly created representations of Earth's surface are known as maps. Features such as roads, rivers, and buildings are represented by symbols.

On a globe or map, precise positioning of places is determined by a universally accepted grid system. This system consists of lines of latitude, represented by parallels, and lines of longitude, represented by meridians.
Sort the following statements as either qualitative or quantitative.
Qualitative - the population of the world has been steadily growing, most of the worlds highest mountains are located in the Himalayan mountain range, in 2005 the atlantic ocean had its most active hurricane season in history Quantitative - according to the united states geological survey mt st helens ejected more than 2.79km2 of material into the atmosphere during it eruption in 1980, the north atlantic ocean is widening at a rate of 25 mm/yr
Complete the sentences below by dragging and dropping the correct word or phrase.
The height of a feature above sea level is its elevation. The vertical distance below sea level is depth. The difference in elevation of one feature relative to another is relief. Cliffs and slopes that drop sharply in elevation are steep slopes, whereas topography that is less steep is a gentle slope. Gradient refers to how much vertical distance changes over some horizontal distance.

The mathematical relationship between actual distance on the ground and its representation on a map is known as scale.
Complete the paragraph below by dragging the correct word or phrase to fill in the blank.
The starting point on this grid system for determining latitudinal location is the Equator, while the starting point for determining longitudinal location is the Prime Meridian.
Earth consists of four overlapping spheres — the atmosphere, biosphere, hydrosphere, and lithosphere — each of which interacts with the other three spheres. Drag each of the following descriptions of these different spheres to the correct location.
atmosphere - extends mostly to 100 km biosphere - can extend to 10 km up hydrosphere - glaciers lithosphere - upper part of mantle
