<span>The orbital period will be 5.196 earth years.
The period of an orbit is proportional to the square root of the cube of the semi-major axis. The semi-major axis of earth is 1 AU (actually 1.000001018 AU, but for this problem 1 is close enough). The hypothetical planet will have a semi-major axis of 3 AU. So making the ratios with earth's year being 1, earth's semi-major axis being 1, the planet's year being y, and the planet's semi-major axis being 3, we get the following ratio.
1 / 1^(3/2) = y / 3^(3/2)
Raise the denominators to the 3/2 powers.
1/1 = y/5.196
Multiply both sides by 5.196
5.196 = y
So the orbit period will be 5.196 earth years.</span>
Answer:
<u>Yes , They are architectural structures that shape the geology of earth.</u>
Explanation:
- These geologic structures influence the shape and size of landscape development and determine the degrees to landscape hazards. Folds and faults and other geologic structures accommodate large forces/stress on earth's tectonic plates.
- Foldes are of two types such as Syncline and Anticline. Formed due to the crustal bending and wrapping of the geo sediments or rocks. The youngest at the top and the oldest at the bottom. As antiforms contain comparatively younger folded rock strata.
- Faults are a planar surface within the earth, where the rocks have slid or broken a fault may be caused due to the elastic strains on the rocks, the rocks on either side are shifted in opposite direction and the faults get induced.
- There are many types of faults and folds in the history of the earth's surface, many of these have led to the formation or shaping of mountain ranges and various mountain chains.
- Another example can be of Mount Everest which is a young folded mountain formed from the colloid of the Tethys sea when India was once a part of the Australian continent.
- Plate tectonics is thus directly related to the formation and motion of the plates which mover the entire planet and shape its orogeny
Answer:
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
Explanation:
Sea drilling cores are one way to get samples that can be used for analysis whereby some information such as type of sediment on the seafloor and type of rock on the seafloor can be known. Surface samplers can be collected from sediment at very top layers or inside deep of the ocean floor. These samples could have animals hidden, , water and some particles that can be analysed in the muddy deep, devices such as Coring devices can be used in collection of cores. The information that can be determined directly by analyzing seafloor drill cores are;
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
D. single- and simple multi-celled organisms
Although more complex animals like invertebrates and multi-celled organisms began to appear, it was very late compared to the original, simpler organisms for which the Precambrian time is characterized by.
People should learn about the currents, waves, and tides just in case of an emergency or the tides are too high. The people should know if their worried about their structure of their home, or worried about their safety.
