This is the Moho discontinuity; the boundary between the Earthโs crust & mantle. Usually many km below the ocean floor, this is just 1 of 2 locations on Earth where itโs visible at the surface.
This map predicts the inflation rate all around the world for this year.
โAfter the invasion of by in February, the organization revised their inflation projections upwards โ by 1.8% for developed countries and 2.8% for developing nations.
Countries experiencing conflict, upheaval or major economic problems in 2022 are expected to see inflation rates far above the global average of 7.4%.
More than three-quarters of all agricultural land, and perhaps 30 percent of all land, is used for livestock (including the cultivation of animal feed). Here's a look at livestock production around the world....
The Jing River meanders through a valley, surrounded by farmland and small villages in Chunhua County, China.
Nice figure showing meandering rivers in barren and vegetated landscapes.
Gravitational map of the Earth ๐
NASA's GRACE satellite has generated a geoid map of the earth based on the magnitude and shape of the globe and shows us an interesting image.
In the picture, we can see several warped dots and various color shades, which represent the magnitude of gravity at that specific point. From what we see, the distribution of matter on earth is not perfectly uniform and therefore neither is gravity.
According to this distribution, the lesser-serious area would be near the Indian Ocean, while in the central part of Europe and the north of the Atlantic Ocean there is the highest index of gravity.
Happy day to all friends.

Morphological parameters of a dune (simulated): total length L, height H and width W.
This diagram depicts rivers feeding into a lake. Where the river enters the water body, the water's flow decelerates, sediments drop out, and a delta forms, depositing a prism of sediment that tapers out toward the lake's interior. Progressive build-out of the delta through time leads to the formation of sediments that are inclined in the direction toward the lake body.

Brian Gooteeโs illustrated history, โGeologic Timeline of Grand Canyonโ, unwinds the paleogeography, sea level change, rocks, tectonism, magmatism and prominent life forms into a savory dish.
Image: Cross section of Grand Canyon that accompanies the 'Timeline'.
The Grand Canyon in northern Arizona is Americaโs greatest geologic wonder. Shaped by erosion of the Colorado River and its tributaries, the Canyon offers a landscape of grand-in-themselves side canyons, buttes, mesas and plateaus, with an unprecedented window into 2 billion years of Earth history.

Natural and urban Water cycle
When precipitation falls, how does it move into and through the ground? (When precipitation falls on the ground, it can run down the surface (runoff) or it can move into the ground. Water moves through the ground because sediments are permeable.
If the sediments are very permeable, the water can pe*****te deep into the ground, but if they are less permeable, the water will not be able to flow very deep into the ground.)........
What effects have humans had on the natural movement of water? (Humans have made a lot of the surface impermeable with buildings and pavement. The water cannot easily enter the ground through paved surfaces because they are impermeable
