The main U.S. goal in the Southeast Asia War was to protect South Vietnam -- initially from a local communist insurgency and later from conquest by communist North Vietnam. The U.S. also hoped to prevent the spread of communism to other nearby countries. ... The U.S. gave France military assistance in fighting insurgents
Answer:
D. Mars takes a longer time to orbit the Sun than Mercury
Explanation:
Mercury is closer to the Sun than Mars, therefore it has a smaller orbit. One year on Mercury is 88 Earth days and One year on Mars is 687 Earth days.
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Landslides into bays and lakes can generate huge tsunami of local extent. The tsunamis associated with bays and lakes are so large because of their constricted topography.
Bay is a water body which is partially surrounded by land and is usually smaller and less enclosed than a gulf. However, the mouth of the bay is wider than gulf. The wave height increases as it comes near the shore, and it depends almost entirely upon the submarine topography offshore. Steeper shorelines tend to produce higher tsunami waves. Tsunamis can also occur in lacustrine environments. In lakes, the huge tsunamis are mainly generated because of the drastic mass-movement processes which displaces large volumes of water and triggered by seismic or aseismic phenomenon.

Answer:
High sea surface temperature and High rainfall
Explanation:
<em>El Niño</em> is a pattern of climate that causes the unusual warming of surface waters in the eastern part of the tropical Pacific Ocean. It affects the temperature of the ocean and changes the strength and speed of its currents, coastal fisheries' health, and local weather from South America to Australia and beyond.
It begins when warm water in the western part of the tropical Pacific Ocean moves toward the eastern part of the tropical Pacific Ocean along the equator. Usually, warm water pools near Indonesia and the Philippines, but during <em>El Niño</em>, the warmest water of the Pacific Ocean assembles at the eastern part of the tropical pacific ocean.
Moreover, trade winds weaken in the central and western part of the tropical Pacific Ocean that weaken the upwelling of nutrient-full cold water to cool warm surface water at the eastern tropical Pacific Ocean. This warm surface water of eastern part of tropical Pacific Ocean warms the atmosphere that empowers moisture-rich air to develop into thunderstorms.
In this way <em>El Niño - Southern Oscillation Event </em>causes the rise in temperature of sea surface and high rainfall at eastern part of the tropical Pacific Ocean.
