Answer:
On their mode of formation
Explanation:
The classification of rocks into three major categories is strictly based on their mode of formation.
Rocks are naturally formed aggregates of minerals. Based on mode of formation, they can be classified into;
- Igneous rocks: these rocks are formed by the cooling and solidification of molten magma.
- Sedimentary rocks are formed by the compaction and lithification of sediment.
- Metamorphic rocks: these are changed rocks that have been formed by subjecting rocks to pressure and temperature conditions which causes an alteration of their minerology.
Answer:
B Winds blow in a straight line parallel to contour lines on a weather map
Explanation:
Geostrophic Wind -
It is the pattern of the wind , when the flow of wind is exactly parallel to the contour lines of the weather map .
It is a theoretical wind which results from the balance between the pressure gradient force and the Coriolis force .
Hence , the correct description for the Geostrophic Wind is option ( b ) .
The 90-degree angle would be hotter since this is receiving the most direct sunlight concentrated in a smaller area. In areas at the equator, the angle of incoming rays from the Sun is perpendicular (90 degrees) to the Earth's surface during all days of the year. Such areas experience warm climates throughout the year
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.
