Answer:
a. cross-beds
Explanation:
Lithified sand dunes are formed when marine, or in this case, aeolian sand dunes become compacted or hardened. Deposition of minerals on these hardened surfaces creates layers on inclined surfaces. These layers get stacked over time, which creates interesting patterns and, as this stacking occurs on tilted surfaces, they form cross patterns. This entire process is called cross-bedding.
Ripple marks are almost uniform patterns usually forming in one direction and plane, which cannot form cross-patterns.
Mud cracks form when a muddy sediment dries up, leaving almost hexagonal cracks behind, a very different type of pattern.
Graded beds are the systematic change in grain size, usually arranging with coarses sediments at the base, and progressively finer grains at the surface. This also cannot form cross patterns.
Lines of latitude measure north-south position between the poles the equator is defined as 0° the pool is the 90° north and the south pool is 90° south lines of latitude are all parallel to each other does they are often referred to as parallels
Answer:
B. 5% ; 1/4 or one-fourth
Explanation:
North America's population is 5% or less than 5% of the whole worlds population. Americans make or have more than 20% of the whole worlds income so it would be around one-fourth of the whole world's.
