Answer:
C. It produces a magnetic field around the Earth.
Explanation:
Core is the innermost part of the earth that contains mainly iron and nickel in molten form (under very high temperature and pressure). The density of core is higher than mantle. Because of presence of iron and nickel, it produces a magnetic field around the earth.
This magnetic field forms the magnetosphere of the Atmosphere and this protects the Earth from the Sun flares and the Solar winds from the Sun. Had this magnetosphere been absent the Earth could have been burnt.

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.

<span>The four main systems of the
Earth are the rocks, water, air and life. Mountains, volcanoes, hills, plateaus,
sand, pebbles represent the rocks. These are where most of the plants and vegetation
takes place. Also, these are where most of the organisms that lives on land take
place. Oceans, rivers, ponds, lakes, waterfalls represent the water. These are
where most of the organisms that lives on water is located. It is said that earth
consists of 70% of water and the rest are land. Air is the reason why all of
the microorganisms living on earth are alive because of its composition, 21%
oxygen and 79% nitrogen. And life, the organisms that dwells on earth.</span>
