**Gravity **and **heat **is thought to be an important cause of plate tectonic motion.

What is a plate tectonic?
The core heat of the **Earth supplies **the fuel necessary for plate tectonics, whereas the "ridge push" and "slab pull" **gravitational forces **are what really move the plates.
According to the widely recognized scientific hypothesis known as tectonic activity, the **Earth's **oceanic **crust **is made up of several huge plate boundaries which have been steadily shifting .
Because of the high heat so at Earth's core, which leads the hot magma in the underlying mantle to move, **bands **at the crust shift .

Plate tectonic motion is primarily caused by gravitational forces such as slab pull and ridge push, combined with heat from the Earth's interior that drives mantle convection. These forces interact to move tectonic plates over time. Understanding these mechanisms is essential for studying geological activity like earthquakes and volcanic eruptions.

Bangun ruang yang memiliki 2 rusuk lengkung, alas dan tutup berbentuk lingkaran dan tidak memiliki titik sudut adalah tabung (silinder).PembahasanTabung memiliki ciri-ciri sebagai berikut :Memiliki 3 sisi, yaitu 2 sisi berbentuk lingkaran (alas dan tutup) dan satu sisi lengkung (selimut tabung)Tidak memiliki titik sudutMemiliki 2 rusukMemiliki jari-jari dan diameterSelimut tabung akan membentuk persegi panjang jika selimut dibuka dan direbahkanSisi alas dan tutup tabung sejajar dan kongruen (bentuk dan ukurannya sama)Rumus luas permukaan tabung yaitu :L = 2πr² + 2πrtatau dapat disederhanakan menjadi :L = 2πr(r + t)Di mana :L = luas permukaan tabungπ = 3,14 atau [tex]\frac{22}{7}[/tex]r = jari-jari lingkaran tabungt = tinggi tabungContoh soal :Seorang perajin kayu ingin membuat meja dari batang pohon yang berbentuk tabung dengan panjang diameter 28 cm dan tinggi 50 cm. Berapakah luas permukaan dari batang kayu tersebut?PembahasanDiketahui:d= 28 cm --> r = [tex]\frac{1}{2}[/tex] × d = 14 cmt= 50 cmDitanya: berapa luas permukaan kayu?Jawab:L = 2πr(r + t)L = 2 × [tex]\frac{22}{7}[/tex] × 14 (14 + 50)L = 88 cm × 64 cmL = 5.632 cm2Semoga membantu
