Ríos Marcianos ¡¿AL REVÉS?!

The video explores how light and shadow can affect our perception of landscapes, using a photo of Mars as an example. It discusses the debate over whether certain features are valleys or ridges, introducing the concept of inverted reliefs. These occur when geological processes make riverbeds more resistant to erosion than surrounding rock, causing them to protrude over time. The video also suggests studying similar phenomena on Earth to better understand these processes.

What can cause confusion in distinguishing features in a landscape image?

• The color of the landscape

• The symmetry of light and shadow

• The size of the features

• The type of camera used

What does the presence of a winding pattern on Mars suggest?

• There were strong winds

• There was liquid water

• There was vegetation

• There was volcanic activity

How can riverbeds become more resistant to erosion over time?

• By being frozen

• Through the accumulation of cement-like minerals

• Through volcanic activity

• By being covered in vegetation

What natural phenomenon is used as an analogy to explain inverted reliefs?

• Sand dunes in the desert

• Footprints in the snow

• Cloud formations in the sky

• Waves on a beach

What tool can be used to find examples of inverted reliefs on Earth?

• Google Earth

• Google Maps

• NASA's website

• Weather forecasting tools
