Berlin, Germany - September 24th, 2009

Berlin, right, is the capital city of Germany and the country’s largest city, with a population of 3.4 million within its city limits. It is the second most populous city and the eighth most populous urban area in the European Union.

Berlin is located in eastern Germany, about 70 kilometers (44 miles) west of the border with Poland in an area with marshy terrain. Around one third of the city’s territory is composed of forests, parks, gardens, rivers and lakes. Substantial parts of the city extend onto the low plateaus on both sides of the Spree Valley.

Geographically embedded in the European Plains, Berlin is influenced by a temperate seasonal climate. Summers are warm with average high temperatures of 22–25°C (mid 70s F) and lows of 12–14°C (mid 50s F). Winters are cold with average high temperatures of 4°C (upper 30s F) and lows of −2 to 0°C (upper 20s and low 30s F).

Sediments in the Gulf of Venezuela (top center) leave thick light brown sediments by the Paraguaná Peninsula on the east side of the gulf, and greenish sediments on the west side by the Guajira Peninsula.

The Gulf, also known as the Gulf of Coquivacoa, by the Venezuelan states of Zulia and Falcón and the Colombian department (state) of Guajira.

It is connected to Lake Maracaibo, in Venezuela to the south, by the 54 km Tablazo Strait. The lake, appearing silvery here due to sun glint, is large and brackish. It is fed by numerous rivers, the largest being the Catatumbo.

The navy blue waters of Lake Nasser, a vast reservoir in southern Egypt and northern Sudan, contrast against the surrounding arid desert. It was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1970.

This image focuses on the upper reaches of the lake in Egypt, and the dam itself is in fact located near the top. Lake Nasser is some 550 km long and 35 km across at its widest point, also visible here. It covers a total surface area of 5,250 km² and has a storage capacity of some 157 km³ of water.

Iturup Island, belonging to the southern Kuril Islands, but disputed by Russia and Japan, runs diagonally across this  orthorectified image between the Sea of Okhotsk (left) and the North Atlantic Ocean (right). A chain of volcanic massifs stretches northeast to southwest along the length of the island.

Here, from bottom to top,  are the Berutarube stratovocano (at the tip of the island), the submerged caldera rim of the Lvinaya Past volcano, the Atsonupuri stratovolcano (west coast), the Bogatyr Ridge stratovolcano (center), the Grozny Group complex volcano (just northeast of the bay on the east coast), and the Baransky stratovolcano (near the east coast, just northeast of the previous).
