The time it takes for Earth to around the sun is 1 year. (rotate or revolve) 4. Which of the following distances is roughly the distance between the sun and the Earth? a. 1 AU b.
The chromosphere is the layer above the visible photosphere. 2. Solar energy passes through this region on its way out from the centre of the Sun. The temperature of this layer ranges between 6 000 ̊C and 20 000 ̊C. 3.
(1) The orbit of each planet is an ellipse with the Sun at one focus. (2) As a planet moves around its orbit, it sweeps out equal areas in equal times. (3) More distant planets orbit the Sun at slower average speeds, obeying the mathematical relationship p2 = a3. h. How does the Earth rotate and how does that relate to day and night or the seasons? The Earth rotates on its axis and orbits the Sun.
(a) Comparing the January map with the July map, describe one region of the world that exhibits a large annual temperature range (the difference between the January and July average temperatures): Siberia. (b) What explains this large annual temperature range? Siberia is located near the eastern end of the world’s largest land mass (Asia) and blocked by mountain ranges from moderating oceanic influences. (c) Describe one region of the world that exhibits a small annual temperature range. The areas between the Tropic of Capricorn and Tropic of Cancer or equatorial belt.

So the radian is the measure of how close a degree is to a complete circle. * How do special right triangles directly relate to the unit circle? There are two types of special right triangle, 90, 60, 30 and 45, 45, 90. With both triangles, the angles of degrees are directly related to the x and y values on the unit circle. With the case of 90, 60, 30 and 90, 45, 45, the angles are relative to the sin of its value on the unit circle.
bfly_recent.gifFrom the research, sunspots do not appear at random over the surface of the sun but are concentrated in two latitude bands on either side of the equator. The sunspots are greatly related to our climate. While the solar cycle has been nearly regular during the last 300 years, there was a period of 70 years during the 17th and 18th centuries when very few sunspots were seen (even though telescopes were widely used). This drop in sunspot number coincided with the timing of the little ice age in Europe, implying a Sun- to-climate connection. limb_flare_sm.jpg (5710 bytes)Solar flares are tremendous explosions on the surface of the Sun.

Cooks first journey was in 1768 and his objective was to observe the plant Venus as it passed between the earth and the sun – this observation would help astronomers to calculate the distance of the sun from earth, he also hoped to find the southern continent. He visited Tahiti where he made observations of Venus, the Society Islands and New Zealand. He mapped most of the two main islands of New Zealand. His second expidition was to either discover the southern hemisphere or prove that it didnt exist. He went below 70 deg latitude that was the farthest any European had ever
Physical size = angular size x 2 x distance / 360 • Understand that constellations are groups of stars as seen from the Earth – the stars may not be close to each other at all • Our view of the celestial sphere is determined by where we stand on the Earth o Study the diagrams that show the path of stars as they rise and set and how those paths appear to differ depending on your location on the Earth • Know what causes the seasons (tilt of the Earth’s axis to it’s orbital plane) o Depend on how Earth’s axis affects the directness of sunlight o Sun’s altitude is also higher in Summer and Lower in Winter Summer solstice – highest path Winter solstice – lowest path Equinoxes – sun rises at exactly due east and sets exactly due west • Review the Moon’s phases • New Moon • Waxing (Right side of moon visible) o Waxing
